对引进的15个鹰嘴豆品种(系)的籽粒产量及其构成因素进行了比较,并应用相关、偏相关及通径分析研究了产量构成因素和相互关系。筛选出两个高产品种(系)ICCV 96853和 ICCV 96852,相关分析中各性状与产量的相关性为：单株粒数>荚粒数>百粒质量。在所有品种(系)中,单株粒数、荚粒数和百粒质量与产量呈极显著偏相关,各性状对产量影响的重要程度为：单株粒数>百粒质量>荚粒数。通径分析发现单株粒数和百粒质量是影响产量的2个主要因素,可作为快速筛选高产鹰嘴豆种质的主要参考性状。

The yield and yield components of 15 chickpea genotypes introduced were compared for screening high yield genotype.Simple correlation,partial correlation and path analysis were applied for studying the rela-tionships between yield components and yield,aimed at providing theoretical basis for fast breeding of chickpea in the northwest arid region.Two high-yield genotypes ICCV 96853 and ICCV 96852 were screened in the ex-periment.The correlation coefficient of yield and yield traits were ranked as grain number per plant>seeds per pod>hundred-grain weight.In all genotypes,grain number per plant,seeds per pod and hundred-grain weight exhibited extremely significant partial correlation and the importance of the effect on the yield for each index was grain number per plant>hundred-grain weight>seeds per pod.Path analysis indicated that grain number per plant and hundred-grain weight were two major factors to influence the yield and could be as main reference indicators to quickly screen high-yield chickpea germplasm.
