The measurement and characterization of genotypic variance in segregating single cross populations of corn (Zea mays L.)
Abstract
Breeding procedures for yield have generally followed the successful course of overcoming the limiting factors, rather than by direct combination of productivity genes. However, the latter may have accompanied the former. The advent of hybrid corn is an exceptional example but after the initial advance further progress has usually resulted from selection of inbred lines against some inherent weakness. The question has been raised whether once the selection against these limiting factors has reached its limit, further advance is possible and practicable. The answer for any character depends on the existence of genetic variations and their magnitude relative to the variations caused by environmental influences.
