以凤豆14号、苏03021、启豆2号等12个秋播蚕豆品种为参试材料,考察了生育期、株高、荚长、单株夹数、单株粒数、百粒重和单株产量等7个主要性状之间的相关关系,并通过通径分析建立了单株产量(Y)的线性回归方程。结果表明,7个农艺性状间存在复杂的相关关系,其中单株荚数与单株产量之间表现出极显著的正相关性,而生育期与单株产量之间表现出显著的负相关性;各性状对单株产量的直接贡献率由高到低依次为单株荚数>荚长>株高>生育期>百粒重>单株粒数;单株产量(Y)的线性回归方程为:Y=-8.423+1.281X4+1.757X3;单株荚数(X4)、荚长(X3)被保留在最优方程中。
Twelve broadleaf broad bean varieties, Fudou No. 14, Su03021 and Qidou No.2, were used as tested materials to study the effects of growth stage, plant height, pod length, number of single plant, number of single plant, Yield per plant and other seven major traits, and established a linear regression equation of yield per plant (Y) through the path analysis. The results showed that there were complex correlations among the seven agronomic traits, among which there was a significant positive correlation between pods per plant and the yield per plant, while there was a significant negative correlation between plant growth and single plant yield ; The direct contribution rate of each trait to single plant yield from high to low was pod number per plant> pod length> plant height> growth period> 100-grain weight> grain number per plant; linear regression equation of single plant yield (Y) As follows: Y = -8.423 + 1.281X4 + 1.757X3; pod number per plant (X4) and pod length (X3) were retained in the optimal equation.
