Abstract

F, hybrids between 14 chickpea varieties Lagere studied for heterosis and heritability estimates in various traits. The results showed that there were significant differences between genotypes for all the characters studied. The high heterotic effects were recorded for secondary branches, biological yield. No. of pods/plant, grain yield and plant height. The hybrid of C727 and CM72 exhibited maximum heterosis for branches per plant, biological yield and pods/plant. Another hybrid. "ICC13416 X C727" showed maximum heterotic effect for grain yield. High Heritability estimates for different characters were also recorded in some crosses. The hybrid "F8750BC X. F85-114C" exhibited high heritability estimates for plant height, biological yield, pods/plants, grain yield and 100 seed weight. Another hybrid (F87-508 X F85-114C) exhibited high heritability for plant height and grain yield whereas F84-508C X ICC13301 showed high heritability for 100 seed weight. The high heritability observed in some crosses/hybrids indicated that an effective genetic improvement in chickpea could be made through the selection of single plants from segregating populations of these hybrids. Simultaneous study of heterosis and coupled with high heritability were observed in ICC13728 X CAI18608 for no. of secondary branches. be genetically based as dominant proportion of its variability was heritable. Therefore, this hybrid could be used electively for the simultaneous improvement of more than one character through selection of single plants with combination of various traits.
