Of the 10 highest yielding strains four are selec- tions from Sixty-Day, two from Burt, two from a hybrid of two strains of Burt, one from Welcome, and one from the hybrid Sixty- Day X Probsteier. Only three of these 10 selections have been de- rived from hybrids. Eight of the 10 highest yielding selections are early in maturing, the average date of ripening for the six years being before July 15. The highest yield obtained in the 4-year test is.

This high average is due largely to the ex- tremely high yield of this selection in 1912, 117 bushels, while other selections from the same hybrid which yielded as well in previous years ranged from 60 to 80 bushels. This selection is not yet fixed, as it still shows considerable variation in some characters. This may explain, in part at least, its high yield. It will be further selected in the future. Six closely related selections from series 8, Danish Island X Asia Minor Rustproof, ranged from 59 to 64 bushels hi average yield. The highest yield obtained from any selection from a commercial variety in this test was 58 bushels from the Welcome selection, 123-5. Of the 25 selections which averaged 54 bushels or more in yield for 40361°—14 2. Please note that these images are extracted from scan
