| 摘 要： | 以干辣椒地方品种为材料，对其主要数量性状与单株产量的相关遗传力进行了相关及通径分析，结果表明：各性状与单株产量的相关遗传力均低于单株产量的遗传力，仅利用某一性状作间接选择的效率比对单株产量作直接选择的效率低；果实的本身性状对单株产量的直接作用和间接作用都较大，而单株结果数的作用不明显；加强对果长及果重的间接选择，适当控制侧枝数和节位数，其高产选择效果最佳．

| Abstract: | In this report.the correlative heritability of quantitative characters of hot pep-per is studied by means of correlative analysis and path analysis.The conclusion so are:(1)all correlative heritability betlveen yield per plant and other main quantitative traits are lowerthan the heritability of yield per plant,and the efficiency is lower when only one quantitativecharacter is selected indirectly than that of yield per plant is selected directly.(2)The effectsto yield are obvious when properties of fruit in itself are selected directly or indirectly,butthe effects to number of fruit per plant are not obvious.(3)If the fruit length.Weight perfruit are selected indirectly and the number of branch and node of the first flower are re-strained.the effect of high yield selection is best. |
