为了探讨亚有限型大豆品种的单株生产潜力,在不同栽培条件下对辽宁和俄亥俄的16个品种进行了植株形态、产量构成因素的比较。结果表明,俄亥俄品种的平均分枝数、单株英数、单株粒数和单株粒重都高于辽宁品种;而辽宁品种的平均株高、节间长度和百粒重都大于俄亥俄品种。俄亥俄品种和辽宁品种各性状与单株产量的关联序不同,单株英数、单株粒数是限制辽宁省亚有限型大豆品种单株产量的主要因素。
In order to explore the potential yield per plant of sub-limited soybean varieties, plant morphology and yield components of 16 cultivars in Liaoning and Ohio were compared under different cultivation conditions. The results showed that the average number of branches, the number of single plant per plant, the number of single plant per plant and the grain weight per plant of Ohio variety were higher than those of Liaoning variety. The average plant height, internode length and hundred kernel weight of Liaoning variety were greater than that of Ohio variety . The correlations between the traits of Ohio varieties and Liaoning varieties and the yield per plant were different. The number of plants per plant and the number of grains per plant were the main factors limiting the yield per plant of sub-limited-type soybean varieties in Liaoning Province.
