摘要:

采用经过初次测产、一次测产表现优良的20份杂交大豆品种作为试验材料,研究大豆杂交种杂种优势,结果表明大豆杂交种具有明显的杂种优势,参试的20份杂交大豆组合中比高产对照黑农38号增产的组合19个,增产幅度为2.39-61.33%,其中增产15%以上的组合11个,占参试组合的55%;增产2.39-14.76%的组合8个,占参试组合的40%;减产组合一个(-11.4%),占参试组合的5%。产量性状分析表明,不同性状变异程度不同。杂交种产量优势主要来自于三粒荚数、四粒荚数、单株荚数、单株粒数、单株产量、分枝数等产量性状。

Abstract:

The study used twenty hybrid soybean varieties which through the initial and first yield testing as test material, in order to study soybean hybrid heterosis. The results show that the hybrid soybean variety have significant advantages in yield, the yield of 19 combinations increased than the high-yield control heinong 38, the range of 2.39-61.33%. Yield-related traits analysis showed that different traits have the different variation degrees. Soybean Hybrid yield advantage mainly come from three pods, four pods, pods number, seed number per plant, yield per plant, number of branches and other production traits.
