摘要
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 。
By the correlation and path-coefficient analysis of characters in Hedysalun Laeve Min.,the results is that these were significantly positive correlations between seed yield and its studyed agronomic characters escept the number of plant per slump.The direct path-coefficients of 7 characters above on seed yield per plant were 0 258,0 252,0 225,0 204,0 194,0 025and-0 124seperately.
