SPRING WHEAT FIELD PLOTS

Experiments with spring wheat in 1952 included varietal field plot trials of 26 varieties and selections and nursery trials of approximately 500 strains.

VARIETAL EXPERIMENTS

Twenty-three varieties of hard red spring wheat and two varieties of amber durum wheat were seeded in the 1952 Dickinson Experiment Station varietal field plot trials. The search for high yielding rust resistant wheats possessing satisfactory milling and baking quality has led to numerous changes in this trial. New this year were five wheats, Ns. 3880, a Lee x Mida sib., Ns. 3654, from the cross Lee x Ns. 3175, Ns. 3780, from the cross Am10 x Newthatch, Ns. 4035, from the cross Mida x Vesta and Chinook, a new wheat from Canada.

Included in the top ten highest yielding hard red spring wheats in the Dickinson trials this year are: Ns. 4035, Red Thatcher, Pilot, Ns. 4036 (which is a Thatcher selection), Rival, Mida, Thatcher, N. No. 2313 (a selection from the cross N. No. 1750 x Timstein), Ns. 3780 and Chinook. All of the above listed wheats averaged 12.5 bushels or more per acre in the 1952 trial. Highest yield was 15.3 bushels per acre from Ns. 4035 and the lowest yield in the entire trial was 6.9 bushels per acre produced by N. No. 2211, from the cross 1764 x Henry.

Comparison of long term average yields shows that the varieties Mida, Pilot, Cadet and Rival have practically the same average for the past ten year period, 1943-1952. Thatcher, the only other variety in the Dickinson trials that is widely grown in this area has averaged 93 percent of the yield of Mida for the ten year period, 1943-1952. Mida has outyielded all other varieties included in the Dickinson trials for two years or more by a wide margin, with the exception of the two Thatcher selections which have averaged about the same as Mida in 1951 and 1952.

Three obsolete varieties, Haynes Bluestem, Red Fife and Marquis, still being carried in these trials for purposes of comparison, have been completely outclassed by the newer strains. Over the past ten years these old varieties have produced only a little more than three fourths as much as the top yielders in this trial.

Data from the 1952 variety trials with wheat are presented in table 30.

Comparative yields for wheat varieties in the trials at the Dickinson Experiment Station since 1930 are summarized in table 31

Milling, baking, and analytical data from Dickinson samples are summarized in table 32.
