蓖麻子实产量是受多基因控制的数量性状，并且与其它数量性状有一定的连带关系。在育种中，杂交F2代是分离世代，明确这些性状的选择指标，对提高育种效率至关重要。本文试图通过遗传力分析和通径分析，计算蓖麻各性状的遗传力大小和对子实产量所起的直接和间接作用的相对重要性，为确定育种早代性状选择目标提供依据。
The yield of castor bean is a quantitative trait controlled by multiple genes, and it has a certain relationship with other quantitative traits. F2 breeding in breeding is the generation of offspring, a clear selection of these traits indicators, to improve the efficiency of breeding is essential. In this paper, we attempt to calculate the relative importance of the heritability of each trait and the direct and indirect effects on seed yield through heritability analysis and path analysis, so as to provide basis for determining the target of early traits selection in breeding.
