DIFFERENTIAL FERTILITY RESTORATION ABILITY OF SOME RESTORER LINES IN RICE (ORYZA SATIVA L.)

Published on

The fertility restoration ability of five restorer lines with ten CMS lines was assessed. The
hybrids Intan Mutant A x ARC 11353 R, Mangala A x ARC 11353 R and Mangala A x IR
9761·19·1 R had more than 70% pollen fertility, but, they did not have good seed set.
Therefore, spikelet fertility (0/.) was taken as criterian for the restoration ability of R lines.
Based on this, the line ARC 11353 R is considered as the best restorer followed by IR 36 R
for WA source of cytoplasm. IR 46 Rand IR 54 R are effective r~storersfor O. niV4r4 source
of cytoplasm. However, variation in the restoration ability of R lines for the same CMS
source was also observed.
