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

Published on Nov 01, 2019 12:50 PM

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.
