提高小麦品种稳产性、适应性的后代选育策略研究

西农８７２７的成功选育为稳产性、适应性品种选育提供了借鉴，本试验以西农８７２７小麦品种选育过程中稳定的５个高代选系为材料，采用不同环境条件、不同试点的试验设计，运用Ｅberhart-Rusell分析方法，推算出参试品系的稳定性参数，分析和比较它们的产量稳定性及环境适应性，并据此筛选出适合性强、稳产性好的优良品系，在此基础上，提出了高代出圃选系后代选育的探讨性见解，为今后高产、稳产、广适性小麦新品种的选育提供了一定的方法参考。

Selecting strategy at generations for improving stability, adaptability of wheat variety

The breeding of the new variety Xinong 8727 provided the reference to the breeding of new wheat variety in yield stability and general adaptability.The experiment was designed in different environment condition and site basing on the 5 lines of high generation of Xinong 8727.The stability parameters were caculated using the method of analysis of Eberhart Rusell,and the best line with the yield stability and adaptability was selected by comparing the parameters.The selecting method of Xinong 8727 can be used to breed new wheat variety with high yield,stability and general adaptability.
