dc.description.abstractIn the present investigation, a set of 158 interspecific derivatives, derived from Bushy Mutant x ILWC 0 (C. pinnatifidum) cross were evaluated along with their parents during 2018-19 and 2019-20. Analysis of variance revealed significant differences among the derivatives for all the traits studied. Various superior derivatives were identified for different traits. GLWP 142 was found to be promising for seed yield per plant. High to moderate heritability and genetic advance was observed for plant height, number of pods per plant, biological yield per plant and 100-seed weight. These traits also exhibited significant positive correlations with the seed yield per plant implying their importance in selection for high seed yield per plant. Path analysis revealed significant positive direct effects of number of pods per plant, 100-seed weight, number of seeds per pod and biological yield per plant towards seed yield while the indirect effects for various traits were prominent via biological yield. D2 analysis grouped 158 derivatives and their parents into 13 clusters. Only one derivative (GLWP 55) was found resistant and 45 derivatives were found moderately resistant to Ascochyta Blight. None of the resistant derivative was found for Botrytis Grey Mould while 24 derivatives gave moderately resistant reaction. The genotyping-by-sequencing (GBS) analysis identified 1409 polymorphic SNP markers. Graphical genotyping confirmed the introgressions of varying degree in derivatives from wild parent ILWC 0 (C. pinnatifidum). Single marker analysis identified seven SNP markers linked to Botrytis Grey Mould which could be further utilised for its mapping. The promising derivatives identified for yield and its component traits along with the disease resistance can be utilized in further chickpea breeding programmes for development of high yielding cultivars.en_US
