The present studies were conducted to the estimation of genetic variability and heritability for physiological traits in chickpea (Cicer arietinum L.) under Randomized Completely Block design with two replications in the field of the department of Plant Breeding and Genetics, of RAK College of Agriculture, Sehore (MP), during the crop season 2019- 2020. The high heritability were observed for LA at 45 DAS (99.22%, 99.61%, 93.87%) & 60 DAS (99.87%, 99.88%, 98.91%), LAI at 45 DAS (99.18%, 99.6%, 93.64%) & 60 DAS (99.86%, 99.89%, 98.92%), TDM at 45DAS (97.21%, 9.13%, 99.05%) & 60 DAS (99.2%, 99.59%, 99.55%), NAR (98.06%, 97.24%, 92.9%), CGR (98.62%, 99.28%, 99.18%), chlorophyll index (SPAD) (95.23%, 94.72%, 82.59%) in normal, late and very late sowing conditions as well as the collection of genotypes for these traits could be useful in the above-mentioned environments. As a result, most of the characters were highly heritable and less influenced by the environment The high Genetic advance as per mean was observed for LA at 45 DAS (73.17%, 91.15%, 60.49%) & 60 DAS (85.11%, 64.40%, 68.11%), LAI at 45 DAS (73.12%, 91.06%, 60.07 %) & 60 DAS (85.07%, 64.37%, 68.15%), TDM at 45DAS (70.40%, 74.89%, 53.54%) & 60 DAS (71.79%, 65.27%, 39.49%), NAR (160.61%, 53.33%, 81.64%), CGR (79.16%, 73.90%, 60.10%), chlorophyll index (SPAD) (59.37%, 52.58%, 43.00%) in E-I, E-II & E-III sown environments, which suggested that these characters can be useful for selecting higher yielding genotypes.
