【 摘 要 】

In natural soybean populations, there is no gene resource with high oleic acid content. Induced mutations for this trait are needed to acquire a new gene in mutation breeding. By X-ray irradiation of the seeds, seven high oleic acid mutant lines of soybean var. Bay, M23, T2427, J38, KK21, M11, KK8 and N1095 having multiple alleles of ol at Ol gene locus were produced. The seed yield in M23, T2427, J38 and KK21 lines were compared with that of the original var. Bay in 2007 and 2008, and KK21 line was selected as a novel genetic resource having a high oleic acid content and high seed yield.
