Description
Summary
(1) Practically, it would be helpful in wheat breeding to know whether one could depend on picking out the relatively longest (and accordingly finest appearing) heads, as a method for securing the highest yielding strains. Page 140.
(2) The results of the present experiment indicate that relatively long heads did yield slightly higher than similar heads on other plants, in the first generation after the selection of mother heads. Table 1, page 142.
(3) Whatever may have caused the slight increased yield in the first generation, it failed to persist in following generations; which were produced from seed tracing back to the original mother heads, but without additional selection. Tables 2-5.
(4) At any rate so far as one may generalize at all, the plant may be used as a unit of selection, and the length of central spike, cannot be considered as an indicator of the fitness of a given plant to serve as the mother plant of a line of progeny. Page 149.
