摘　　要：本研究选用矮秆、半矮秆大豆品系,在"窄行密植"栽培模式下种植,分析了产量性状的相关性。结果表明,窄行密植大豆的株高和结荚位、株高和节数、株高和百粒重、节数和结荚位、节数和瘪荚数间的正向相关系数达到显著水平,结荚位和荚数间呈极显著负相关,荚数对产量的通径系数最大,其次为百粒重,其他性状对产量的直接通径系数较小。In this paper short and semi-short soybean lines were used to analyze correlation of yield traits under narrow-row dense cultivation modes. The result showed that plant height and height of podding, plant height and number of nods in main stem, plant height and 100 seed weight, number of node in main stem and height of podding, number of node in main stem and number of unfilled pod of soybean planted under narrow-row dense cultivation were positive correlation respectively, and correlation coefficient of which were significant at 0.01 level, height of podding and number of pod per plant was negatitaive correlation. Path coefficient of number of pod per plant to yield was the largest, and that of 100 seed weight to yield is second, while amount of other path coefficient is little.
