    Abstract:

    In this study, 61 parts the system breeding offspring from cultivar “Daminglv” in eastern Inner Mongolia were test material, through the diversity and path analysis of agronomic traits, to clear the high yield population genetic types and characters of offspring. The result showed that the differences were significant in offspring strains traits among these lines and cultivar in “Daminglv”. The numbers of pods per plant has largest variation coefficient was 31.61%, followed by the grain weight per plant was 28.05%; The genetic diversity of mung bean was rich, the diversity index of pod number was 2.02, number of seeds per pod was 2.01, hundred-grain weight was1.89, the grain weight per plant was 1.96. There were six main types of offspring strains, The order of affect to the characters on the the grain weight per plant was: pod number per plant> seeds per pod> hundred-grain weight> stem section number> plant height. The main characteristics of high-yielding strains indexes was more than 15 g in grain weight per plant, pod number over 30 pods, per pod 8-10 seeds, height 48-60 cm, 9-10 sessions, hundred-grain weight can set standards according to different needs.
