摘要

Seed from F3 generation plants of two reciprocal crosses were evaluated for bruchid resistance, over 28 nF, families of four plants each plus an additional five plants each in 10-11 families. The variables, npercentage adult emergence for a specified period and mean time to emergence, agreed with respect to ndescribing segregation in the resistant, intermediate and susceptible categories. Resistance was expressed nas a recessive character. No differences between families from reciprocal crosses were detected. nThere was evidence for digenic control of resistance in one cross and for monogenic control in the nother, in conjunction with one, or more, modifier or minor gene loci. There was general agreement nbetween the results for the F, generation study and a previous study on the F, generation.
