Description Not Available
Inter-sub-specific hybridization between indica and tropical japonica rice germplasm
is the most efficient approach for broadening the genetic base of hybrid rice parental
lines and enhancing the heterotic potential of hybrids in a tropical country like India.
In the present study, 106 indica/tropical–japonica derived lines were developed
through inter-sub-specific hybridization and screened using functional markers with
respect to the major fertility restorer genes, Rf3 and Rf4, and the wide compatibility
gene, S5n. The fertility restoration ability of newly developed restorers was validated
through test cross nursery performance. The functional markers were observed to
accurately predict the trait of fertility restoration. From the present study, the
decreasing order of efficiency of different gene combinations on fertility restoration
ability are as follows: Rf4/S5n > Rf4/Rf3/S5n > Rf4 > Rf4/Rf3 > Rf3/S5n > Rf3. Based
on multi-trait stability index (MTSI) analysis, the four newly identified restorers, that
is, RP6388-90, RP6382-49, RP6375-81 and RP6368-38, were selected as the top
best performing genotypes with high stability for multiple traits, and these genotypes
will be useful for the development of superior rice hybrids in India
