ABSTRACT
The three male-sterile lines 'ICPA 2043', 'ICPA 2047' and 'ICPA 2092' derived from Cajanus cajanifolius (A4) 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 25th October 2009 to 15th March 2010 for male sterility and fertility. The study of stability of male-sterile lines under different month temperature revealed that the male-sterility was ranged from 84 to 100 % in 'ICPA 2043', from 94 to 100 % in 'ICPA 2047' and from 93 to 100 % in 'ICPA 2092'. All the three male-sterile lines derived from A4 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.
Key words :
Cajanus cajanifolious, Inheritance. Male-sterility, Male-fertility, Pigeonpea, Stability.
