摘　　要：用秩次分析法,对两个年度参加河北省冬麦区中北部区域试验中的7个冬小麦新品系(种)进行了综合评价。通过对各品种表现的平均数分极值H_1,秩次值H_2,环境区分指数Y_M等统计数的计算,进行品种间秩次平均数的多重比较。结果表明,以京冬6号、唐7111、秦麦1号等4个品种在这轮区试中表现优良。7 Winter wheat varieties, which were introduced from the regional test of north and middle Hebei province, were evaluated by the rank analysis method. The grade numerals of average (H1) and rank numerals (H2) of variety trans , and circumstance differentiating index (YM) were calculated, and the multiple comparison were carried out with the rank average of various varieties. The results showed that the Jingdong 6, Tang 7111 and Qinmai 1 were superior to the others.
