摘要
运用相关、通径分析的方法分析了四川省小麦主推品种绵阳 2 6号的产量及其构成因素之间的关系。结果表明 ,绵阳 2 6号小麦品种千粒重的变异不大 ,穗粒数是产量构成的最重要因素 ,合理的有效穗是高产的前提。
The relatons between yield and yield components of “Mianyang 26”,a popular wheat variety at present in Sichuan, were analysed through correlation and path coefficient analysis ways.The result showed that 1000-grain weight of the variety varied little,the reasonable spike number per area was a prerequisite for high yield,and the number of kernels per spike was the most important component of yield.
