Abstract
The present study was undertaken to assess the variations and association among yield and its contributing traits in interspecific derivatives of chickpea. One hundred thirty chickpea interspecific derivatives of four wide crosses were evaluated for various agro-morphological traits. The analysis of variance revealed the presence of sufficient variability among the recombinant lines for all the traits studied. Genotypic and phenotypic coefficients of variation were found to be higher for seed yield per plant, 100-seed weight, plant height and pods per plant. Likewise, moderate PCV and GCV were observed for biological yield per plant and harvest index. Selection will be effective for traits such as plant height, 100-seed weight, biological yield per plant, number of pods per plant, seed yield per plant and harvest index as they showed high heritability along with high genetic advance. Correlation and path coefficient analysis revealed that higher seed yield per plant can be obtained by selecting derivatives with high biological yield per plant, number of pods per plant, 100-seed weight and harvest index. Overall interspecific recombinant lines viz; R-31 (Cross I - PUSA 372 X ILWC 229), R-12, R-27 and R-30 (Cross II - PBG 5 X ILWC 229), R-3 (Cross III -PBG 5 X ILWC 246) and R-6 (Cross IV - BGD 72 X ILWC 246) were found superior over the best check, Him Palam Chana 1 (DKG 986).
