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.
Ningchun 4 is a wheat variety approved in 1981. It is still used as the main push variety in northwestern spring wheat area.Through querying historical archives and collecting regional trial data of Ningxia in recent years, the statistical analysis is conducted.The results show that: Ningchun No.4 showed high yield, and the output was continuously refreshed with the passage of time, both of which were higher than the environmental index of the cultivars in the same period, with small coefficient of variation and regression coefficient and stable yield. Good sex, strong buffering capacity of individual and group, grain with 1, 17 + 18, 5 + 10 high quality subunit combinations, high molecular weight glutenin subunit total quality of 10. Therefore, Ningchun 4 with good stability, adaptability Wide, excellent grain quality characteristics.
