对入选的27株早实核桃优良单株进行产量及其影响因子的相关分析和逐步回归分析。得到了包括平均每果枝坐果数、冠幅、坐果枝率和单果重在内的最优多元线性回归方程;再对入选的4个主要性状进行通径分析,明确了在育种过程的杂种选择中,应选择平均每果枝坐果数、坐果枝率、单果重较高的单株作为丰产性的指标。 Correlation analysis and stepwise regression analysis were conducted on the yield and its influencing factors of the 27 excellent pre-harvest walnuts. The optimal multivariate linear regression equations including the average number of fruit per plant, crown width, fruit setting rate and fruit weight were obtained. The path analysis of the four main traits was carried out, and it was found that in the hybrid selection of breeding process , Should choose the average number of fruit per fruit, fruit yield rate, fruit weight per plant as a high yield indicators.
