Abstract
Progeny derived from six crosses of barleys resistant and susceptible to kernel discoloration were evaluated for resistance in the F2 and F3 generations. Plants were grown in the field under irrigation and inoculated with Bipolaris sorokiniana. Heritability estimates of 27-43% were obtained on an individual F2 plant basis by parent-progeny correlation. Heritability estimates of 48-76% were obtained on a family basis from variance components from replaced F3 nurseries. Distributions of the F2 and F3 populations were nearly continuous and tended to follow a bell shape. Data from both generations failed to confirm a fit to simple hypothesized segregation ratios. Transgressive segregation toward susceptibility was observed in F3 populations of all crosses.This publication has 6 references indexed in Scilit:
