【Abstract】 Germplasm introduced from other countries,e.g.Williams,Clark63 and SRF,were widely used in the soybean breeding programs in Heze,Shandong Province.By using these germplasm,eight varieties including He7308,He84-1 and He84-5 were devel- oped,with the total growing area of more than 1.05 million ha.The genetic contribution rate of the introduced germplasm was estimated to be 13/32.更多还原
