摘要
用秩次分析法 ,对 6个年度参加河北省冬麦区中北部区域试验中的冬小麦新品系产量性状的稳定性进行评价。通过对各品种表现秩次值H2 ,环境区分指数YM ,秩次均方值S2 等统计数的计算 ,进行品种间产量的高低及稳定性比较。对 2
It was by the rank analysis method that yield stabilities of winter wheat varieties attending the regional trials of north-middle part of Hebei province in the past six years have been evaluated so for. After ranking value of different varieties (H 2), mean square value (S 2), as well as environmental index (Y M) were calculated, the stabilities and yield have been compared. Therefore, 22 new varieties were evaluated objected.
