摘要
The objective was to study the genetic basis of lipid content in pea seeds and the extent to which the inheritance of lipid content can be attributed to major genes determining seed shape. The genetic analysis consisted of two full 5 × 5 diallel crosses; one diallel between genotypes differing for genes affecting seed shape (r, rb, di and mifo loci) and the other between genotypes known to differ for lipid content. The results indicated that there was significant additive genetic and dominance variation for percent lipid. Recessive alleles at the r and rb loci have a positive effect on lipid content, while alleles at the di and mifo loci appear to have no effect on lipid content. Copyright © 1990, Wiley Blackwell.
