The three male-sterile lines 'ICPA2043', 'ICPA2047' and 'ICPA2092' derived from Cajanus cajanifolius (A„) cytoplasm were sown in insect proof selfing cage at Marathwada Krishi Vidhypeeth, Parbhani. The observations were recorded from initiation of flowering up to maturity at the interval of 15 days starting from 25'" October 2009 to 15'" March 2010 for male sterility and fertility. The study of stability of male-sterile lines under different month temperature revealed that the malesterility was ranged from 84 to 100 % in 'ICPA2043', from 94 to 100 % in 'ICPA2047' and from 93 to 100 % in 'ICPA 2092'. All the three male-sterile lines derived from A, cytoplasm exhibited stability through out the crop season without any effect of increase or decrease in temperature, indicating male-sterility in A4 cytoplasm was independent of environment condition.
