Super rice breeding in China has been very successful over the past 3 decades, and the Chinese government has made great efforts to support breeding and cultivation of both conventional and hybrid super rice. In this review, we focus on the progress in and potential of super rice breeding. After the establishment of the breeding theory and strategy of "generating an ideotype with strong heterosis through inter-subspecies hybridization, by using gene pyramiding to combine elite traits through composite-crossing to breed super rice varieties with both ideotype and strong hybrid vigor", a series of major breakthroughs have been achieved in both conventional and super hybrid rice breeding. A number of new genetic materials with ideotype have been created successfully, and the Ministry of Agriculture of China has approved 156 novel super rice varieties and combinations for commercialization. During the Developing the Super Rice Varieties Program, great attention has also been paid to the integration and demonstration of the rice production technology. Collaboration between industry and university researchers has led to technological innovations and initiation of a demonstration system for super hybrid rice. With widespread cultivation of super rice with higher quality and yield, as well as resistance or tolerance to abiotic or biotic stresses, the yield of rice production per unit has reached a new level. In addition to increased quality and yield, hybrid rice breeding has also led to improvements in many other agronomic traits, such as resistance to pests and diseases, resistance to lodging, and optimized light distribution in population. Achievements in super rice breeding and innovation in rice production have made major contributions to the progress in rice sciences and worldwide food security. 相似文献

福建省杂交水稻选育研究现状与展望 总被引:2,自引:0,他引:2
统计1991年至2010年福建省审定的184个杂交稻品种的信息,回顾和综述了福建省近20 a杂交水稻育种所取得的成就,通过对配制这些杂交稻品种所用的亲本进行统计和分析认为:(1)福建省杂交稻品种主要是由本省科技人员培育而成的,占审定数的85.87%.(2)“八五”、“九五”期间福建省杂交水稻育种应用的不育系比较单一,“十五”、“十一五”期间涉及的不育系数量比较多,Ⅱ-32A、龙特浦A、珍汕97A、冈46A、D62A、SE21S是配组频率较多的不育系.(3)蜀恢527、明恢86、明恢63、福恢673、闽恢3301是配组频率较多的恢复系.(4)福建省杂交水稻育种不足之处是育成品种中优质品种和丰、抗、优等综合性状好的品种相对较少;能抗多种病虫害和适合轻简栽培的杂交稻品种缺乏.根据上述分析,提出福建省杂交稻未来育种思路与策略. 相似文献
