| 摘 要： | 用秩次分析法,对6个年度河北省夏大豆区域试验中的大豆新品种(系)产量性状及稳定性进行评价。通过对各品种产量表现秩次值H2,环境区分指数YM,秩次均方值S2等统计数的计算,剔除了对品种产量差异区分能力弱的试验点次(试验环境),及试验点次过少的品种(系),进行品种间产量的高低及稳定性比较。对6年滚动试验中36个可评价参试品种给予客观、公正的评价。证明了用秩次分析法对农作物区域试验产量性状进行评价是可行的。

| Abstract: | It was by the rank analysis method that yield and stabilities of summer soybean varieties attending the regional trials of south-middle part of Hebei province in the past six years were appraised. By the calculation of the ranking value of different varieties(H2), environmental index(YM), and mean square value(S2), the testing spots(environments)which barely distinguishing the yield levels and the varieties with lack of valuable spots were rejected .After that, yield and stabilities were compared. 36 of the new varieties in six years were appraised objectively and justly. The result shows the method is feasible. |
