蚕豆特矮秆突变体的遗传研究 Studies on the Inheritance of a Dwarf Mutant in Vicia faba L.

Dwarf Enong 82, which was derived from the unique dwarf mutant discovered in China, was crosscd with the commercial broad bean cultivar Qidou 1. From the crossing six basic generations were generated for studing the genetical behaviors of plant height and two related charactCrs i.e. node length and number of nodes. The resu1ts showed that the three characters were governed by nuc1ear genes. The difference in plant height between two parents was related to a loci, which was designated Df-df Genera tion mcan analyses revealed that the additive-dominance model was adequate to interpreting the inherit ance of thc three characters. The estimates of number of genes controlling these characterswere the same astheresults with Mendlian methods.
