摘　　要：采用高稳系数法,分析了参加2004～2005年河南省区域试验的小麦新品种(系)的产量及其构成因素的高稳系数,结果表明:产量的高产稳产性有赖于产量构成因素的协调发展;在成穗数相同的条件下,在影响品种产量的高产稳产性方面穗粒数大于千粒重;参试品种中,周99343、郑农17、许农5号、04中36、鄢陵22的高产稳产性最好。The method of the high and stability coefficient was used to evaluate the yield and its component of new wheat varieties from the regional experiment of 2004-2005 in Henan Province.The results showed that high-stability of the yield relied on its components coordinative development. The grain number per spike had bigger effect on high-stability of the yield than the thousand-grain-weight under same spike number per hm^2 of wheat varieties.The highest and stablest rarity was Zhou 99343, Zhengnongl 7, Xunong 5, 04zhong36 and Yanling22, respectively.
