宁麦 9号是江苏省农科院以扬 86-1 7为母本、西风为父本 ,采用集团选择法选育而成的高产、稳产小麦新品种。该方法早期 ( F2 、F3、F4)以产量为主要选择指标 ,以组合为单位进行初步测产 ,有利于提高群体中高产基因型的筛选频率 ;F3、F4进行异地多点产量鉴定 ,有利于选出广适性品种 ;早期 ( F2～ 4)就按大田生产密度种植 ,有利于个体性状的真实表达 ,并可提高育种效率 ;后期对高代材料进行多点产量和抗病 (逆 )性鉴定 ,同时对品质进行综合分析 ,从而保证了所选品种具有良好的综合性状
Ningmai 9 is a new high-yielding and stable-yielding wheat variety which is selected from the group selection method by Jiangsu Academy of Agricultural Sciences with 86-1 7 as the female parent and west wind as the male parent. In the early stage (F2, F3, F4), the yield was the main selection index, and the pre-test production was carried out in combination, which was helpful to improve the screening frequency of high-yielding genotypes in the population. F3 and F4 were more effective in identification of multi- Select the most suitable varieties; early (F2 ~ 4) according to the density of field planting, is conducive to the true expression of individual traits, and can improve the breeding efficiency; late generation of high yield material and disease resistance Identification, at the same time a comprehensive analysis of quality, thus ensuring the selected varieties have a good comprehensive trait
