芝麻主要性状与籽粒产量之间的相关及通径分析

ANALYSES OF CORRELATION AND PATH BETWEEN MAIN CHARACTERS AND SEED YIELD IN SESAME

本文对30个品种(系)的主要性状与籽粒产量间进行了相关通径分析。结果表明单株蒴果数和千粒重对单株产量的直接效应值较大。因此,在培育高产品种时,应以株高适中、单株结蒴多、结蒴密、千粒重高的类型作为主要选择目标。

In this paper,correlations and path analysis have been done between main characters and seed yield in 30 varieties(lines).The result showed that the number of capsules per plant and the 1000-seed weight have a higher direct-effect on yield per plant.So,for selecting high-yielding varieties,aim would be to select the types with middle plant height,more number of capsules per plant,dense capsules,and high 1000-seed weight.
