不同鹰嘴豆品种（系）籽粒产量及其构成因素分析

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）ICCV96853和ICCV96852，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。

Analysis of the grain yield and yield components on different chickpea genotypes

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 g per pl rain number per plant） hundred-grain weight） seeds ant and hundred-grain weight were two major factors indicators to quickly screen high-yield chickpea germplasm. per pod. Path analysis indicated that grain number to influence the yield and could be as main reference
