Abstract

Rice is a staple food crop that feed half of the world’s population. Hybrid rice, a high yielding rice is the most potent technology of increasing rice productivity. Hybrid rice seed production system involves two and three line system. Three line method or cytoplasmic genic male sterile system has been found the most effective genetic tool for developing rice hybrids. Use of the environment genic male sterility (EGMS) system in two-line breeding is simple, efficient, inexpensive and eliminates the limitations associated with the cytoplasmic-genetic male sterility (CGMS) system. The EGMS system advantage includes no need of maintainer line, no need of restorer line and does not have any negative effect of cytoplasm. EGMS system of hybrid seed production is more economic and efficient than to the CGMS method. This article discusses the salient features of two line system over three line system of seed production in hybrid rice.
