Abstract

The relative magnitude of the variances in maize is important to the corn breeder because the type and amount of each variance present influences the type of breeding program and the success from that program. This investigation was designed to study the effects of thermal neutron radiation, selection and recombination on the genetic variance components of several characters of maize from the cross of two homozygous lines, N6 and N15. The results of this experiment indicate that a missing value can be computed in the case of a missing cross without serious bias when the number of missing crosses is small.
