| The soybean germplasm collection which includes 15 Korean imported varieties was estimated at Plant Resources Center, An Khanh, Hoai Duc, Ha Noi in summer 2012 and spring 2013. This research showed that 6 varieties produced stable yield contributing characters and high individual yield; and 10 varieties had significant higher grain yield than the control variety. The experiment determined 13 varieties with short and medium growth duration (85- 105 days); 2 remaining varieties with long growth duration (greater than 106 days) in comparison to 90 days of the control variety. 15 varieties had an average pest and disease resistant. |
