摘　　要：宁春4号是1981年通过审定的小麦品种,至今仍被用作西北春麦区的主推品种.通过查询历史档案资料和搜集近年宁夏区域试验资料,运用统计学方法进行分析.结果表明:宁春4号丰产性突出,产量随着时间的推移不断刷新,并且均比同时期区试品种的环境指数高,变异系数和回归系数小,稳产性能高.同时,宁春4号产量三因素间协调性好,个体和群体缓冲力强,籽粒含有1、17+18、5+10优质亚基组合,高分子量麦谷蛋白亚基品质总和为10.因此,宁春4号具备稳产性好、适应性广、籽粒品质优良的特点.Elite spring wheat variety Ningchun 4 that registered in 1981,up to date, as a major parent for wheat breeding has been widely planted in Northwest of China. By querying the historical archives and collection in Ningxia regional test data, using the method of statistical analysis to draw： Ningchun 4 has high yield, the yield with the passage of time and constantly refresh, and compared with periods of high environmental index. At the same time, the yield of good coordination between the three factors, individual and group buffer capacity, grain containing 1, 17＋18, 5＋10 subunits combinations, high molecular weight glutenin subunits and quality of the sum of 10 points, In Ningchun 4 has the characteristics of good stability, wide adaptability and good grain quality .
