本研究以10个有限型和10个无限型(或亚有限型)栽培大豆品种为材料,采用逐步回归方法分析了大豆产量的构成因素。试验设计为随机区组,4次重复。结果表明:单株荚数一个因素即可分别解释有限型、中间型、无限型大豆产量变异的72.80％、79.93％和80.80％。单株荚数、生育期、主茎上始花到终花的日数和株高在三种类型的品种中都是重要的产量构成因素。
In this study, 10 finite and 10 infinitive (or sub-limited) cultivars of soybean were used as materials to analyze the components of soybean yield by stepwise regression. The trial was designed as a randomized block with 4 replicates. The results showed that one factor per pod could explain 72.80%, 79.93% and 80.80% of the variation of the yield of the limited type, intermediate type and infinity type, respectively. The number of pods per plant, the period of growth, the number of days from initiation to final flower on the main stem, and plant height are important yield components in all three types of cultivars.
