| 摘 要： | 在点播条件下，对４２个早熟燕麦材料７个性状的表现及其性状间的相关性进行了研究。结果表明：单株地上生物量和单株粒数的变异程度较大，株高和千粒重两性状的变异相对较小；单株地上生物量和单株粒数与单株粒重有极显著的正相关关系。通径分析表明单株地上生物量和单株粒数对单株粒重的直接效应较大，千粒重和株高对单株粒重的直接效应相对较小。

| Abstract: | traits of 42 accessions of early oat(Avena sativa L.)were investigated and correlation analyses between grain weight per plant and other traits were conducted after dibbling.The results showed that both above ground biomass and grain number per plant of the accessions varied obviously,and they had signifficant positive correlation with grain weight per plant(GWPP).Comparatively,both plant height and 1000 grain weight varied slightly among the accessions.The path coefficent analysis revealed that above ground biomass and grain number per plant had higher direct effects on GWPP than plant height and 1000 grain weight. \ \ |
