Breeding for yield in crop plants
1931
Woodworth, C.M.
In presenting these ideas, the thought has been to lay particular emphasis on the importance of breeding for yield as such. Present methods appear rather haphazard and unscientific, because selections and crosses are made without a knowledge of yield attributes and their genetic relationships to yield and to each other. Strains have not been sufficiently evaluated. A cross is made between two strains in the hope of getting something that is superior in yield to either parent. Chance plays a very large part in this--too large a part. It is probably too much to hope that the element of chance can be eliminated altogether in breeding for yield, but if we can by ever so little lessen the part that chance plays something has been accomplished.
