摘要：

Correlation coefficients and path coefficients of fresh pod yield and yield components of vegetable soybean were investigated in 2010. Thirty vegetable soybean genotypes were grown at the rate of 28 plants m(-2)in a randomized complete block design with three replications in field condition in Northeast China. The results showed that fresh pod yield was positively correlated with 3-seed pod per plant (0.81**), 2-seed,pod per plant (0.76**), 2-seed pod width (0.59) and 100-fresh seed weight (0.47**), and negatively correlated with plant height (-0.75) and 2-seed pod length' (-0.64). Path coefficient analysis also revealed that 3-seed pod per plant (0.58) had the greatest direct positive effect on fresh pod yield, followed by 2-seed pod per plant (0.56), 2-seed pod width (0.31), and 100 fresh seed weight (0.23), whereas plant height (-0.36) and 2-seed length (-0.35) had negative direct effect on fresh pod yield. It wasconcluded that more considerations should be given to the number of seed pod per plant, 2-seed pod width, 100-fresh seed weight, plant height, and 2-seed pod length when selecting higher fresh pod yield of vegetable soybean.
