The present study was carried out with 12 promising kabuli chickpea lines sown normal sown and late sown environments. High PCV and GCV was accounted for the traits seed yield per plant, number of effective pods per plant, number of total pods per plant, seed size and harvest index in timely and late sown environments. Flower initiation (days) and 50 % flowering (days) noted for high heritability along with high genetic advance as percentage of mean. Positive and significant correlation of seed yield per plant was found with harvest index, number of total pods per plant, number of effective pods per plant, seed size and biological yield per plant under both conditions. Path coefficient analysis revealed that highest direct effect on seed yield was contributed by number of effective pods per plant. Based on minimum yield reduction percentage KAK 2, JGK 2, ICCV 07311 and ICCV 06301 have been identified as heat tolerant lines. The potential for indirect selection for heat stress tolerance using these associated characters may be useful to the breeder to formulate appropriate breeding plans for selection of the genotype which tolerate high temperature conditions.
