【Abstract】 Through field tests and observation of 16 soybean cultivars on morphological, physiological and yield characters, a cultivated technology for super high yielding was made, and two elite lines were selected by their high yield-above 4 875kg/hm 2 in experimental plot. By the help of the technology, the new line Liao 21051 with the yield of 4 908kg/hm 2 in the area of 3 134m 2 was obtained, which was the highest yield in the north spring soybean area in China.更多还原
