应用灰色关联度分析法对昭觉县高寒粳稻新品系分析评价

Application of Grey System Relational Analysis to the Evaluation of New Lines of Alpine-japonica Rice in Zhaojue

应用灰色关联度分析法对昭觉县高寒粳稻品比试验中的20个高寒稻新品系的产量、品质和抗病性等11个主要性状进行综合分析。结果表明,应用加权关联度进行分析评价的结果优于一般关联度的评价结果,与田间综合评价情况更相符,其综合评价排序结果与产量排序基本一致,新品系中H14、H3综合性状最佳,H2、H9次之。

This paper comprehensive analyzed the 11th main characters such as grain yield , quality and resistance, etc. of 20th new lines of Alpine-japonica rice in Zhaojue by using grey system relational analysis. The results showed that the evaluation result of grey system relational analysis better than general system relational analysis. The evaluation result agreed with comprehensive analysis in field, and the sequencing result of comprehensive analysis agreed with the sequencing result of grain yield. The comprehensive characters of H14 and H3 were best, H2 and H9 were second.
