摘要
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。
To discuss yield potential of individual plant between semi-determinate soybeans, the comparison on morphological traits and yield components were conducted under different cultivation environments with 16 cultivars from Liaoning Province and Ohio,USA. The results showed that branches,pods per plant, seeds per plant and seed weight per plant of cultivars from Ohio were higher than those from Liaoning Province; while plant height,internode length and 100-seed weight of cultivars from Ohio were less than those from Liaoning Province. The correlation be- tween agronomic traits and yield per plant was different,among cultivars from Liaoning Province and Ohio. The main factors limiting yield potential of individual plant were pods per plant and seeds per plant in Liaoning Province.
