ABSTRACT
Hybrid rice systems are based on three line cytoplasmic male sterility (CMS) which has been an efficient tool in commercialization of hybrid rice technology. Therefore, identification of potential restorers in rice is the basic step in development of rice hybrids. In present study, 50 drought tolerant lines were crossed to one cytoplasmic male sterile line i.e. CMS59A F1s were analyzed for pollen fertility (1% I-KI solution) and spikelet fertility. Based on the fertility restoration in F1s, 15 genotypes were restorers, 25 partial restorers and 10 partial maintainers were obtained. Among the 50 lines, SVHR-3005, NH12-103R, KMP-128, RNR-21280, KMP-175, SV-315-081R, MTU-1075 and MTU-1001 are considered as promising restorers.
Key words: Hybrid rice, Restorers, Maintainers, Pollen Sterility, Spikelet Fertility.
