The Grey Correlation Analysis in the Selection of Stable Rice Line

摘要:

本文采用灰色系统理论对水稻稳定株系的诸多性状因子进行综合评价和定量分析。分析结果表明：①将诸多的性状因子融为一体，在理想的标准品种模式高选择压力下进行测评，避免了优良材料的丢失和淘汰。②依据灰色关联度的排序，吉96-2146名列第一，吉96-2798名列第二，吉96-2572名列第三。

Abstract:

The charaters of the stable rice line are synthelically evaluated and quantitativty anal ysed, according to the grey system theory in this paper. The result shows: ①mixing all the characters together and testing under high slecting prevsure according to the ideal standard variety moddle , can avoid the good material being lost and eliminated. ②According to the grey correlation order Ji 96-2146 is 1 st, Ji 96-2798 the 2nd, Ji 96-2572 the 3rd.
