摘要：

The genetics of seed weight was studied in crosses between thc cultivated lentil L. culinaris and the wild species L. orientalis and L. ervoides. Seed weight was found to be under polygenic control with additive dominant gene action and with partial dominance of low seed weight alleles. High heretability estimates were obtained in the analysed crosses. Nuclear-cytoplasmic interaction was found to affect seed weight in crosses involving accession No. 138 of L. orientalis. Factors affecting seed weight were linked to morphological and DNA markers distributed over several linkage groups. High seed weight in segregating generations were usually associated with alleles of marker loci originated from the cultivated parent. Factors enhancing seed weight were detected in accession No.138 of L. orientalis, indicating the potential of wild genetic resources for seed weight improvement in lentil.
