An experiment was two factorial design with a three set of genotypes viz., Annigeri-1, JG-11 and JG-14 were sown under different dates of sowing (D1, D2, D3 D4 and D5) from 40th standard meteorological week (SMW) to 48th SMW and a study was conducted to know the effect of temperature regimes on morpho-phenological character, flowering pattern and flowering duration and their contribution to yield of chickpea genotypes. Among the dates, D3 temperature regimes took significantly higher primary and secondary branches (9.6 and 12.0 respectively) with optimum phenological parameter like days to flower initiation (37.9 days), days to fifty per cent flowering (42.9 days) and more number of flowers per day per plant (172), with all these character which produces higher yield by minimizing flower drop and floral abortion under maximum of minimum temperature compare to other temperature regimes and the genotypes JG-11 recorded significantly higher yield (28.32 q ha-1) due to higher primary branches (9.1), took less number of days to flower initiation (36.1 days) and fifty percent flowering (40.7 days) with the optimum duration of flowering (26.2 days) and total number of flowers (156) and recorded higher yield. But the genotype, JG-14 is thermo tolerant recorded optimum yield under D3 temperature regime, which was having less number of flowers than the others and also there was no much variation in the yield from D1 to D5 temperature regime compared to other genotypes.
