The analysis of variance revealed the existence of significant amount of genetic variability in the material for all the traits. All the genotypes were treated with three treatments separately (Mesorhizobium sp. strain CH1233 (S1); Mesorhizobium sp. strain CH810 (S2); Vesicular arbuscular mycorrhiza (Glomus fasiculatum) and one set was used as Control that is left uninoculated. These were grown separately following Randomized Block Design with three replications in each treatment. Comparative analysis indicated wide differences between treatments and behavior of genotypes in different environments. In general S1 and VAM showed beneficial interaction for maximum number of traits for all genotypes. The affect of VAM was the most apparent among treatments. High GCV was found for characters; number of nodules per plant (all the treatments and control), nodule weight per plant (treatment S1, S2 and VAM), shoot dry weight per plant (S2 and control), seed yield per plant (VAM and control) and 100 seed weight (S1 treatment). High heritability with high genetic advance was observed for the characters like seed yield, number of pods per plant and number of nodules per plant, while high heritability with medium genetic advance was found for nitrogen content in shoot, shoot dry weight per plant, days to 50% flowering, 100 seed weight and VAM infection. On overall basis genotypes viz. HC-3, HC-5, GL94022, HC-5, ICC5003LN, HK2, GNG663 and BG362 were observed to be better performing and responsive to bioinoculants having one or more superior traits. These genotypes performing better for specific traits can be used as parents in hybridization programme for improvement of that particular trait.enPlanting, Genotypes, Root nodulation, Chickpeas, Nitrogen, Developmental stages, Sowing, Yields, Biological phenomena, GeneticsThesis
