Abstract:
According to relevant literature, it was counted that the information of 184 hybrid rice varieties which had been registered in Fujian Province from 1991 to 2010. The achievements of hybrid rice breeding of Fujian Province in recent 20 years were reviewed. The parents of 184 registered hybrid rice varieties were analyzed in this paper. Results showed that these varieties were mainly bred by scientific and technical personnel of Fujian Province, making up 85.87% of the total. The utilization of male sterile lines in the breeding of hybrid rice was relatively simple during the 8th and 9th "Five-Year Plan". But, more male sterile lines were used during the 10th and 11th "Five-Year Plan", such as "Ⅱ-32A", "LongtepuA", "Zhenshan97A","Gang46A", "D62A" and "SE21S". Higher frequency applications restorer lines had "Shuhui527", "Minghui86", "Minghui63", "Fuhui673" and "Minhui3301" from 1991 to 2010. However, the disadvantages of hybrid rice breeding in Fujian were fewer of varieties which possessed high quality or good comprehensive characters of high yield, resistant and quality, and lack of varieties which possessed resistance to multiple pests and diseases, and suitability of simplified cultivation. Based on the above analysis, the strategy of hybrid rice breeding was proposed in this paper.
