摘　　要：根据区域试验多年资料,系统分析了大穗型、大粒型和多穗型小麦品种成产三要素的相互关系及其产量表现,认为河南省中北部小麦超高产(9000ke/hm^2以上)应当以三要素比较协调的多穗、中等穗型品种为主,目前较好的代表品种是温麦6号;提出了河南省今后小麦育种应当以逐步提高多穗型品种的穗粒数和千粒重,三要素协调发展为主攻方向。Based on the data from the regional tests of 10 years, the interrelation of 3 yield components of wheat varieties with more-grain type, heavy-grain type and more-spike type and their yield performance are analysed systematically. It is considered that in the middle north ern area of Henan Province the varieties with more-spike and middle-spike type should be mainly screened for super-high-yielding wheat (over 9000 kg/667 hm2) and Wenmai 6 is the good typi cal variety at present. It is suggested that gradually increasing spike number, grain number and grain weight of wheat variety with more-spike type should be the main objective in wheat breed ing of Henan Province in the future.
