Abstract: Present study includes five CMS lines of Pigeonpea with A4 cytoplasm at two locations viz. ICRISAT Patancheru (Telangana) and BAU Sabour (Bihar). Observations on each plant for pollen sterility were recorded at the onset of flowering in September. The second round of sterility evaluation was done in December. The final observations were recorded in February. Result of study revealed that higher temperature of ICRISAT Patancheru (Telangana) have positive effect on the sterility level and higher sterility was reported in all CMS lines(> 90%) whereas at BAU Sabour temperature respectively low so sterility level was also low (< 90%).
