对羊柴的 7个农艺性状和单株种子产量进行了相关和通径分析。结果表明 ,7个农艺性状中除了果层高度外 ,其它性状都与单株种子产量呈显著或极显著正相关。 7个农艺性状对单株种子产量的直接通径系数次序为 :每序结荚数 (X5) >每株花序数 (X3 ) >果层高 (X1) >每果种子粒数 (X6) >每序小花数 (X4) >每株丛单株数 (X2 ) >千粒重 (X7)。要提高种子产量 ,首先应提高每花序结荚数
Correlation and path analysis were conducted on seven agronomic traits and seed yield per plant. The results showed that all of the seven agronomic traits had significant or highly significant positive correlation with the seed yield per plant, except for the height of the fruit layer. The order of direct path coefficient of seven agronomic traits per plant was: X5> X3> X1> X6> Flowers per order (X4)> Number of plants per plant (X2)> 1000-grain weight (X7). To increase seed yield, first increase the number of pods per inflorescence
