| 摘 要： | 经过1996－2000年5年的研究，共配制杂种优势测定组合199个，通过第一次产量鉴定表明，大豆具有明显的杂种优势，并筛选出F1超高亲，超对照优势率均为正值，且二者平均值大于10％的较强优势组合161个，占全部组合的80．9％，F1超高亲，超对照优势率均大于20％的高优势组合69个占全部组合的34％，并通过第二次产量鉴定进一步筛选出稳定的高优势组合4个，即合9661，9672，9731，97143，此外研究结果还表明，大豆杂种优势具有较好的稳定性，在不同年度，不同地点优势率变化不大，且趋势一致。

| Abstract: | 199 crossing combinations of Soybean heterosis were stadied i n 1996～2000. The first yield test indicated that the soybean had clea r heterosis . At the same time, 161 comparative high-superiority combinatio ns selected by the test amounted to 80.9% in total. And 69 combinations are amang the high-superiority crosses in total with 34%. From the second test, four stable high-superiority crosses were selected, They are 9661, 9672, 9 731, 97143. Additionally, The results proved that the soybean heterosis ha d better stability and varied a little with different years and places. |
