以36个糯玉米杂交组合为试材,调查10个与糯玉米鲜穗单株生产力有关的性状,在进行简单相关、表型相关,基因型相关分析的基础上,根据性状间的相关和因果关系,建立糯玉米鲜穗单株生产力通径图,进行通径分析,结果是,每穗粒数、出籽率,一行粒数,果穗长度,果穗粗度,生育期等性状的提高对促进扫玉米鲜穗单株生产力是有利的;百粒重、单位面积株数等性状对糯玉米鲜穗单株生产力呈负向效应,对产量构成因素性状的直接效应和性状间的间接效应也做出了分析,为糯玉米育种中的自交系培育,亲本选配,提高选择效果提供科学的参考和依据。
Based on simple correlation, phenotypic correlation and genotypic correlation analysis, 10 hybrids of 36 waxy maize were used as materials to investigate the correlation between the traits The results showed that the increase of traits such as grain number per spike, seed-yield rate, grain per line, ear length, ear diameter, growth period and so on, Spinning single ear productivity of corn was beneficial; 100-grain weight, number of plant per unit area and other traits had a negative effect on the fresh ear productivity per plant of waxy corn, and the direct effect on the yield component traits and the indirect effect between the traits In order to provide a scientific reference and basis for breeding inbred lines of waxy corn breeding, selection of parents and improvement of selection effect,
