Abstract: 71 landraces were selected for the analysis of genetic variability of quantitative characters of adzuki bean variety source of Tangshan, such as means , heritability , genotypic coeffcient of variation ( GCV) ,and genetic advance (ΔG’) , etc. The results showed that the adzuki bean variety source of Tangshan were poor in the maturity types. They had flourishing vegetative plant , good yield traits , and relatively big grain. The selection of these traits with higher genotypic coeffcient of variation ( GCV) and genetic advance (ΔG′) , such as branch number of main stem , pods perplant , grain weight per plant , yield per plant, days before flowering , 100-seed weight and grain per pod were available. The heritabilities of growing trait , branch number of main stem and 100-seed weight were high. The selection for these traits could be conducted in the early generations. The yield per plot with moderate heritibility could be selected in a little higher generation. The selection for plant height , pods per plant, grains per pod and grain weight per plant should be carried out in higher generation in which the genetic base tends to be pure and stabile.
