小麦群体结构与农艺性状的相关性研究

摘要

In order to research the relationship between population structure and agronomic traits of wheat,15 new wheat varieties were analyzed. The results showed that the heading period and mature period,the maximum tiller number and effective panicles,effective panicle and yield were positively correlated,the maximum tiller number,effective panicles,heading stage and maturity stage were negatively related to 1 000 grain weight.%为研究小麦群体结构与农艺性状之间的关系，对15个小麦新品种进行分析，结果表明：抽穗时间与成熟期、最高茎蘖数与有效穗数、有效穗数与产量均呈正相关，最高茎蘖数、有效穗数、抽穗期、成熟期均与千粒重呈极显著负相关。
