| Abstract/Description: | Hybrid rice technology is one of the potential options for increasing rice yield. The present study was carried out to know the effectiveness of wide compatibility trait. The compatibility as measured by percentage spikelet fertility in F1s revealed it to vary between the IR58025WCB having wide compatibility (WC) gene and IR58025B. The F1s were also analyzed for pollen fertility with I2-KI solution. In crossing of IR58025WCB with indica, japonica and tropical japonica testers, group mean spikelet fertility 83.62%, 77.75% and 69.16% respectively; and in comparison to crossing of recurrent parent IR58025B with indica, japonica and tropical japonica testers, group mean spikelet fertility 81.80%, 43.90% and 59.94% respectively. The anticipated increase in group mean percentage overcome with indica, japonica and tropical japonica testers 2.50%, 13.93% and 36.99% for pollen fertility and 2.22%, 77.11% and 15.38% for spikelet fertility respectively. Such kind of approach helps in the combination of genetic background of the two dissimilar sub-species. The effectiveness of wide compatibility trait in improved parental line would be used for exploitation indica and japonica in hybrid rice breeding programme. |
