摘要： 本文研究了30个基因型的6个性状与单株籽粒产量间及6个性状优势强度与单株产量优势强度间的相关性,并进行了通径分析。6个性状与单株产量间的相关系数均为正值。两组通径分析表明,穗粒数对单株产量的直接效应最大,其次是千粒重。穗长优势对单株产量优势的影响无论是直接还是间接的效应均较小。生育期和株高优势对单株产量优势

Abstract: Relationships between 6 characters and grain yield/plant of the 30genotypes from a incomplete diallel cross in sorghum were studied by sim-ple correlation and path-coefficient analysis.The results are as follows:1.The grain yield/plant was positively correlated with all the 6 characters,but signific
