Status and Prospects of Hybrid Rice Breeding in Jiangsu, China

摘要

Research on hybrid rice in Jiangsu Province began in 1970. Great progress has been made since then, which can be divided into three stages according to the development of hybrid rice breeding and production in Jiangsu Province. The first stage was beginning stage from 1970 to 1980, when progress was mainly made in cytoplasmic male sterile line breeding. The second stage could be described as developing stage, from 1980 to 1995, when indica hybrid rice was rapidly popularized, and japonica hybrid rice became popular later. Starting in 1996, hybrid rice breeding in Jiangsu Province entered the third stage, when both indica and japonica hybrid rice breeding in the three - line system or intersub-specific hybrid rice breeding in the two - line system made a great breakthrough with the successful breeding of the hybrids "Te - you 559", "9 You 138" and "Li-angyoupeijiu". The developing trend of hybrid rice breeding in Jiangsu Province is also discussed in the paper.
