Abstract

The 300 parts of VF germplasm materials in Sichuan and Chongqing areas were divided into 12 groups according to the population way, then by group clustering method, 5 candidates were collected (in the proportion of 30%, 25%, 20%, 15% and 10%) and their genetic diversity indexes were compared and the significance of their difference was tested. Finally 60 parts of key germ plasm were established under 20% of the sampling rate. Through testing the characteristic value coincidence of key germ plasma, the mean compliance rate, the standard deviation rate and the coefficient of variation were 98.07%, 94.12% and 95.70%, which showed that the primary key germ plasm was able to represent genetic variation of the total germplasm.
