STARK URBANA, ILLINOIS, JUNE, 1926 SUMMARY Wheat is decidedly susceptible to climatic conditions and varieties differ widely in their adaptation to environment. As Illinois extends nearly 400 miles from north to south, marked variations in climate occur, and one of the prob- lems in successful wheat production is to find those varieties that are particu- larly suited to the different sections. Tests at DeKalb, in the northern part of the state, indicate the superior winter resistance and high yielding capacity of the hard wheats of the Turkey Red type, such as Ilred (Turkey Red 10-110), Minnesota Reliable, Kanred, Red Russian, and Turkey Red (Station strain). Soft varieties that have made a sat- isfactory record are Hardy Northern and Red Cross. These tests have been con- ducted since 1907. During this time 44 varieties have been grown, 19 of which were hard, 23 soft, 1 of unknown origin, and 1 hybrid, one parent of which was a hard wheat. In central Illinois also winter resistance frequently is the deciding factor in successful wheat production. Among the 57 varieties and strains tested at Ur- bana since 1904, those of the Turkey Red type have proved superior in this char- acteristic. Minnesota Reliable, Worlds Champion, Ilred (Turkey Red 10-110), Kanred, Malakof 5-460, and Turkey Red (Station strain) comprise the hard wheats with the best records for a period of eight years or more. Other hard varieties tested for a shorter period which deserve mention are Red Russian, Malakof C. I. No. 4898, Minturki, Kanred 2401, Michikoff, and Blackhull. Soft varieties which have made good records are Indiana Swamp, Dawson Golden Chaff 9-225, Red Rock, Red Cross, Michigan Amber, and Gladden. Soft varieties seem best adapted to the southern section of the state. At Fairfield in Wayne county 41 varieties and strains of wheat were tested from 1906 to 1923. Eight of the varieties were of the Turkey Red type and one was a hybrid, one parent of which was Turkey Red; the remainder were soft varie- ties. Fulcaster, a soft variety, which was taken as the standard variety with which to compare all others, was exceeded only by Illini Chief, also a soft variety, in average yield. Other varieties which were grown for six years or more and which made favorable records on this field are Red Cross (synonym for Harvest Queen), Economy, Marvelous (synonym for Fulcaster), and Jersey Fultz. On the Alhambra field in Madison county Fulcaster has been slightly ex- ceeded by Mediterranean, as a six-year average, while Rudy, Gipsy, Illini Chief, Red Wave, Marvelous, and Jersey Fultz, all soft varieties, during five-year periods have yielded but slightly less than Fulcaster. A description of the varieties used in these tests, together with a summary of their performance on the above fields, will be found on pages 27 to 35. PRODUCTIVENESS OF VARIETIES OF WINTER WHEAT IN ILLINOIS BY ROBERT W. STARK, Associate in Crop Production From the early settlement of Illinois to the present date, wheat has been one of the most important crops grown in the state. Some conception of the magnitude of the industry and the distribution of the wheat-growing sections may be derived from the map on page 4, which shows the acreage by counties grown in 1923. In that year the total production of winter wheat in the state was 60,534,000 bushels, and this crop was harvested from 3,363,000 acres. Extensive wheat growing is confined to certain fairly well-de- fined areas. In general, the principal wheat-growing counties lie east of the Illinois river and east of the Mississippi river south of the mouth of the Illinois. The wheat sections, therefore, include practically all the region covered by the Middle Illinoisan glaciation, the western por- tion of the Lower Illinoisan glaciation, and a smaller area in the same glaciation bordering on the Wabash river. These constitute the two oldest glaciated regions in the state. Variety trials of winter wheat have been conducted at DeKalb in DeKalb county, at Urbana in Champaign county, at Fairfield in Wayne county, at Alhambra in Madison county, and at Cutler in Perry county. The results of these investigations up to and including 1916 are given in Bulletin 201, "Yields of Winter Wheat in Illinois." In the present publication the previous data from the DeKalb, Urbana, and Fairfield fields are repeated, and the further data from these fields for the years 1917 to 1925 inclusive are added. The yields from the Alhambra tests, which were begun in 1919, are also given, but the results of the tests at Cutler, which were begun in 1902 and discon- tinued in 1907, are not repeated. TESTS IN NORTHERN ILLINOIS DEKALB IN DEKALB COUNTY The character of the varieties of wheat adapted to the different sections of Illinois are influenced materially by the wide variations in climatic conditions occurring between the northern and southern boundaries of the state. DeKalb is situated in the northern part of the north-central dis- trict of the state. The average annual precipitation for this section BULLETIN No. 276 [June, is about 34 inches. 1 The average temperature for the winter months is approximately 24.7 F., while the average annual minimum tempera- ture is 16.3 F. below zero. The effect of the long continued low tem- perature is usually lessened by a snowfall of 30 to 35 inches. Winter Wneot Distribution 1923 WINTER WHEAT DISTRIBUTION IN ILLINOIS Data taken from Illinois Crop Statistics for 1923 issued by the Bureau of Agricultural Economics, U. S. Department of Agriculture. A number of soil types occur on this field, but they are all com- mon to the region and are productive. The wheat is grown in a rota- 'Meteorological data taken from Bulletin 208 of this Station, "Climate of Illinois," issued in 1918. 1926} PRODUCTIVENESS OF VARIETIES OF WINTER WHEAT 5 tion of corn, oats, wheat, and alsike clover. The soil treatment con- sists of applications of crop residues and rock phosphate and manure and rock phosphate. Each variety is represented an equal number of times on each system of soil treatment. Variety trials of wheat were begun in 1907 and have been con- tinued to date. During this period 44 different varieties and strains have been tested ; of this number, 19 are hard varieties and 23 are soft. The character of one designated as native is unknown, while another is a hybrid, one parent of which was a hard wheat. During the period of these trials inferior varieties or lesser known strains have been discontinued and other untried varieties substituted. This process of elimination has resulted in the gradual casting out of all but the highest-yielding varieties. The varieties that are now in the test, and have been for a number of years past, constitute, there- fore, with one or two exceptions, the hardiest and most prolific varie- ties tried. The annual yield of the entire list of varieties that have been grown at DeKalb is given in Table 1. Since the different varieties have been grown for irregular periods, average yields manifestly are not comparable. Turkey Red, however, is one of the best varieties tried, and it has been grown during the entire period. The percentage yield of each of the other varieties, with Turkey Red as the standard for comparison, may therefore be calculated by dividing its average yield by the average yield of Turkey Red for the same period. This percentage rating appears in the last column. A summary showing the number of years each variety was grown, together with its average yield and the average yield of the standard variety for the same per- iod, is given in Table 2. During the entire period covered by these tests, 1907 to 1925, seven varieties were tested for six years or more, each of which has a percentage rating greater than Turkey Red (Station strain 1 ). These varieties are, in order of rating, Red Russian, Ilred, 2 (Turkey Red 10-110), Kanred, Hardy Northern, Wisconsin No. 18, Minnesota Re- liable, and Worlds Champion. With the exception of Hardy North- ern, these are all strains of the Turkey Red type. In 1922 a considerable number of varieties were discontinued. Those retained were either the highest-yielding varieties or they pos- sessed characteristics which made it desirable to give them a further trial. The performances of the nine varieties which have been grown continuously during the last six-year period, 1919-1925, are directly comparable (Table 3) . *The Turkey Red designated as "Station" strain lias been grown continu- ously for many years on the University farm and is of no known special selection. 2 Turkey Red 10-110 has recently been given the name Ilred.

In 1920 (the data for which also are not included 1 ) it was again almost an entire failure. Red Rock has shown a decided tendency to be seriously injured in this section by unfavorable winter conditions. When it has survived the winter suc- cessfully, it has proved a heavy yielder. Of the varieties given in Table 3, all belong to the Turkey Red type and are hard red winter wheats, except Red Rock, Red Cross, and Hardy Northern. These latter varieties are awned except Red Cross. Sufficient data concerning the more recent entries in these tests (see yields in columns for 1923, 1924, and 1925, Table 1) have not yet been secured to warrant drawing definite conclusions as to their relative adaptation to the conditions which obtain in this section. TESTS IN CENTRAL ILLINOIS URBANA IN CHAMPAIGN COUNTY The Urbana experiment field lies in the eastern part of central Illinois. This section has an average annual precipitation of about 37 inches. The average temperature for the winter months is approxi- mately 28.8 F. At Urbana, during a 25-year period, the average an- J The data for all varieties grown in 1920 were discarded because of the un- reliability of the threshing records. PRODUCTIVENESS OF VARIETIES OF WINTER WHEAT 11 nual minimum temperature has been 13 F. below zero. This section has an average annual snowfall of 20 to 25 inches. Frequently the snow melts quickly so that it affords little protection to the wheat. The soil of the field on which the Urbana variety trials are con- ducted is Brown Silt Loam, which represents fairly well the better soils of this type thruout this section of the state. In these experiments wheat constitutes one of the crops in a rota- tion of corn, oats, wheat, and red clover. Each variety has been equally represented on plots fertilized with crop residues and rock phosphate, crop residues with rock phosphate and limestone, manure and rock phosphate, and manure with rock phosphate and limestone. Fifty-seven varieties and strains of wheat have been tested during the period 1904 to 1925. Of these varieties 18 are hard wheats, 33 are soft varieties, and 6 are hybrids, one parent of which was a hard wheat. The complete list of these varieties, together with their annual yields and percentage ratings based upon the average yield of Turkey Red (Station strain) for the same periods, is shown in Table 4. A summary showing the number of years each has been tried, and the average yield of each variety compared with the average yield of Turkey Red for the same years, is given in Table 5. If the behavior of these wheats on the Urbana field may be taken as a criterion of their probable performance thruout central Illinois, then it may be concluded that strains of Turkey Red or hybrids of that variety are dependable high-yielding varieties for that section as well as for the northern section. In Table 4 Turkey Red (Station strain) ranks nineteenth. Of the 18 varieties having a higher percent- age rating, Michigan Amber, Dawson Golden Chaff 9-225, and Glad- den are the only ones which are not either of the Turkey type or hybrids with a hard Russian wheat as one parent. A considerable number of the varieties at present competing in these trials have been grown for too short a period to permit definite -conclusions concerning their relative productiveness. Those varieties which have been grown for a period of not less than eight years, from 1918 to 1925 inclusive, are shown in Table 6. Six of the 10 varieties listed in this table are hard wheats; the other 4, Indiana Swamp, Dawson Golden Chaff 9-225, Red Rock, and Red Cross, are soft varieties. During this eight-year period, Indiana Swamp exceeded Turkey Red by 2.3 bushels an acre, tho its average yield for a period of twenty-one years was 2 bushels an acre less than Turkey Red (Table 5). Indiana Swamp has never been extensively grown. It is produced to a limited extent in Illinois, Indiana, Ohio, Kansas, and Texas, under a number of different names. Dawson Golden Chaff 9-225, which ties Minnesota Reliable in ranking second in yield, is a selection from Dawson Golden Chaff. The parent stock is a white wheat, whereas this strain, while containing 12 BULLETIN No. 276 [June, iLJea ^* t"* 00 CO *O ^O^COOO ^ C*3 00 t~f l^ l> t> 1 < O t*- !O O tO O3 H Cl O *O OS O o.S-5 - 2 "ti O N O tO 'O O iO -*f* ** C*J CM N i-< i IO OOOOO O O O O >O ** <** Tf CO *" - ^H i^ ^ Q o OOOOO OOOOO OOOOCS OS O OS O O CSOOOS _ _ _ oo to -^i TJ< oo -to co to ri cTo -in TJI ^i to 10 co co ^J< *H . 10 - oo t* ^* CM to 10 . ro ^H o co . 10 ^* * n I O I 1 * CO t*. t TJ* . t^ . to CO O CM O .

It has not been distributed. Red Rock has given an average yield practically equal to Turkey Red. It has been subject, however, to rather wide annual fluctuations in yield. Red Cross has averaged during this eight-year period only 1.9 bushels an acre less than Turkey Red. It has been rather consistently inferior to Turkey Red, however, the latter exceeding it in yield six of the eight years. Red Cross is susceptible both to the rosette disease and to flag smut, and therefore should not be grown in localities where these diseases are known to exist. Other promising varieties which have been grown from one to five years are Red Russian, Blackhull, Minturki, Kanred 2401, Michigan Amber, Malakof C.I.

Michigan Amber, Gladden, and Hardy Northern are soft wheats; the others are hard varieties. 1926} PRODUCTIVENESS OF VARIETIES OF WINTER WHEAT 17 > C H O < a a O (N IS H T-H W05 1-1 1 I 1o .

The average annual rainfall in this district is 41.5 inches. The winter months have an average annual temperature of 33.1 F., while the average annual minimum temperature is approx- imately 7 F. below zero. Over most of this section the snowfall ranges between 15 and 20 inches. At Fairfield, however, the records indicate less than 15 inches. The soil of this field is Gray Silt Loam On Tight Clay, which rep- resents large areas of relatively infertile land thruout this section. The rotation on this field consisted of two years of legumes alter- nating with one each of corn and wheat. During the last six years the order was as follows: corn, soybeans, wheat, sweet clover. One half the field was tile-drained, while the other remained untiled. The fertilization consisted of crop residues supplemented with rock phos- phate and limestone, and manure with rock phosphate and limestone. Each variety was equally represented on the tiled and untiled land, and on the plots receiving residues with mineral fertilizers, and those receiving manure with mineral fertilizers. This land is normally strongly acid and deficient in organic matter and nitrogen. Very few attempts to grow wheat are made on much of the land of this type thruout Marion, Clay, and Wayne counties. The yields obtained, particularly from 1917 to 1922, clearly indicate the possibilities of producing wheat on such land when the soil is limed and properly fertilized, such fertilization being accomplished partly by means of mineral fertilizers but more especially by the growing and turning under of legume crops. Liming, however, is first necessary in order to produce the legumes abundantly. Variety trials were conducted on this field from 1906 to 1923, at which time the field was discontinued. Altho wheat makes a less vig- orous fall growth in this section than in the more fertile regions, still there was but one year in which the crop was a complete failure. During the seventeen years that wheat was grown at Fairfield, 41 varieties and strains were tested. Fulcaster was taken as the standard variety, and is the only one continued thruout the entire period. The annual yields are given in Table 7, and the percentage rating of each variety based upon the average yield of Fulcaster for the same period is shown in the last column, A summary showing the years each vari- ety was grown, and the average yield compared with the average yield of Fulcaster for the same period, is given in Table 8. Illini Chief is the only variety which gave a percentage rating greater than Fulcaster. It will be observed from Table 8 that in many 19S61 PRODUCTIVENESS OF VARIETIES OF WINTER WHE.\T 19 EH O 2^ < - o 3 3 PS CQ a a v ~' g G 3 3 s H IN 00 COt~Ob- . -^ CO ^H *^ O O O> ClG500iO*O oppoi ossojosoj oioojoso ocsooioo oooooooooo ""*!
