| 摘 要： | 对新近育成的9个旱地高产春小麦新品种(系)的穗数、穗粒数、千粒重和产量4个主要数量性状进行了相关遗传力及其通径分析.结果表明:穗粒数与产量的相关遗传力最高,且对产量的直接作用最大.在旱地种植中,应以争取大穗多粒材料取得高产.

| Abstract: | Correlated heritability study and its path analysis of four major quantitative characterisics eg.Spike/hm~2,Kernels spike,1 000 grain weight and Grain gieldlant/hm~2 of nine cultivars developed recently from all parts of the country showed that correlated heritability of TKW and yield was the highest and the largest direct role to yield.It should be trying to get larger kernels to obtain much higher yield. |
