摘要
分析了３０份山西冬小麦品种的诸性状对产量的作用。结果表明，千粒重、穗粒数对产量贡献较大，每ｈｍ２穗数次之，株高的效应较小。
The relation between yield and main agronomic characters of 30 winter wheat varieties was investigated through relation and path analysis. The results showed that the number of eargrains and weight of 1000 grains had a closest relationship with yield,then the number of ears per ha and the height of plant had litlle influence on the yield.
