Correlation among agronomic traits and factors analysis on yield for Mesona chinensism
-
摘要: 对20份仙草资源的株高(X1)、茎长(X2)、茎粗(X3)、节间长(X4)、叶长(X5)、叶宽(X6)和单株产量(Y1)等7个主要农艺性状进行了相关性分析,并对单株产量因素进行通径分析,结果表明:茎长、株高、茎粗和节间长对单株产量性状有较大的效应关系;茎长、株高与单株产量呈显著正相关;与单株产量主要相关的4个性状中茎长对单株产量的直接正向效应值最大。Abstract: Correlation among main agronomic traits of 20 varieties of Mesona chinensism and the factors affecting their yield were analyzed.The results showed that the stem length,plant height,stem diameter and internodes length had significant effects on the yield per plant.Both the stem length and plant height significantly correlated to the yield,with the stem length being the greatest among all examined traits.
