HARD SPRING WHEAT TRIALS - 1955

Trials with hard spring wheat at the Dickinson Experiment Station this year included: field plot trials of twenty two varieties and selections; the Uniform Regional Spring Wheat Nursery of twenty six entries; the Cooperative Nursery Trial, from Dr. Glenn S. Smith, which included ten entries; the Uniform Bunt Nursery which this year contained twenty nine varieties and selections; the Dickinson F-5 nursery of sixty two selections; the F-4 nursery of thirty seven selections; the F-3 nursery of fifty selections and an F-2 nursery of one hundred forty eight selections. There were fifteen separate plantings in the 1955 F-1 nursery.

WHEAT VARIETY TRIALS

Stem rust was not a serious problem in this area in 1955, and this fact plus favorable planting weather in April and ample rainfall in June combined to produce excellent wheat yields. N. D. 8 was high yielder in the variety trials with an average of 33.4 bushels per acre. N. D. 25 and N. D. 3 ranked second and third with respective yields of 30.6 and 28.9 bushels per acre. Lee, Selkirk and Mida each produced yields of approximately 28.5 bushels per acre.

The highest yielding durum variety was Sentry which yielded 29.7 bushels per acre of good quality wheat which weighed 62.0 pounds per bushel. Lowest yielder was Ld 369 which averaged 21.4 bushels per acre.

Data from this years' wheat variety trial are summarized in table 26.

Average yields for the past ten years are summarized in table 27.

NURSERY TRIALS - 1955

Highest yielding entries in the Uniform Regional Nursery planting grown at Dickinson in 1955 included: Thatcher x Kenya Farmer, C.I. 13209; Thatcher x Kenya Farmer, C.I. 13211. Yaqui 54; Chapingo 53; and R. L. 2563 x Lee, C.I. 13157. Yields from the above listed selections were all above 29.0 bushels per acre. Thatcher in this trial averaged 25.0 bushels and Selkirk produced 27.6 bushels per acre. Test weights were good this year ranging from 55.5 pounds per bushel to 61.0 pounds per bushel with most of the entries weighing in the high fifties.

Stem rust was not a major factor affecting yields this year which helps to account for the high yields from some of the old check varieties included in these trials.

In the Cooperative Cereal Nursery planting at Dickinson this year the highest yield was from Selkirk which averaged 34.1 bushels per acre, followed by N.D. I, N.D. 12, N.D. 33, Ns 3880-227 and Lee, all yielding over 30.0 bushels per acre.

In the F-5 Wheat Nursery one selection averaged 39.0 bushels per acre which was high yield in this trial. Three selections produced over 35.0 bushels per acre and twenty seven entries yielded between 30.0 and 35.0 bushels per acre. Several of these new strains appear promising and will be continued in 1956.

Data summarizing results from these nurseries are included in tables 28, 29, and 30.

In the 1955 Uniform Bunt Nursery infections ranged from zero to 100 percent with 27 of 29 entries being infected.

Data from this years Uniform Bunt Nursery are summarized in table 31.
