Abstract
Two cytoplasmic male sterile (CMS) lines of rice having wild abortive WA and one line with Kalinga cytoplasmic male sterility source were crossed with eleven testers to identify their restorer/maintainer nature. Total of 33 hybrids were subjected to pollen and spikelet fertility analysis along with their parents. Most of the genotypes expressed differential fertility reactions when crossed with CMS lines. Testers were identifying as potential restorers. None of the genotypes were identified as potential maintainer based on pollen and spikelet fertility. Among testers only Kranti was identified as potential restorer for all the 3 CMS lines whereas, Danteshwari was identified as potential restorer for 2 CMS lines IR 58025A and IR 79156A. The other testers viz., MTU 1010, Abhaya, Indira Barani Dhan 1, IR 681444, Chandrahasini, were identified as potential restorer for all three CMS lines. Tester Pusa Basmati was identified as partial maintainer for all the three CMS lines. Potential restorers identified in the present investigation could be used to develop good, high yielding and promising rice hybrids with other genotypes.
