【摘要】 从探索提高C3作物光合效率途径为切入点,在分析作物高光效育种历程阶段的基础上,从大豆高光效育种的总体思路、高光效的光合生理基础、高光效育种理论、高光效高产育种体系、高光效品种选育5个方面讨论了大豆高光效育种。旨在为通过高光效育种途径来提高C3作物光合效率提供理论依据和技术支撑,促进大豆高光效育种的进程。提出了启动C3作物自身C4途径,并将多项高光效功能整合,并与常规育种相结合,可能是提高C3作物光合效率新的突破点,从而确定了大豆高光效育种的总体思路。大豆高光效的光合生理基础是高光效品种的光反应和暗反应过程与常规品种相比都有明显改善,并且它们之间存在密切的连锁相关。大豆高光效育种理论是依据作物遗传育种理论和作物生理学原理构成的。建立在作物生态类型基础上的高光效育种生理遗传基础和高光效的光合生理基础是大豆高光效育种理论基础。依据大豆高光效育种总体思路和理论,通过高光效育种实践建立了大豆高光效高产育种体系,育成了高光效品种黑农39、黑农40和黑农41。更多还原

【Abstract】 On the basis of analyzing the courses of crop breeding for high photosynthetic efficiency(HPE) and improving the photosynthetic efficiency of C3 crop,we discussed soybean breeding for HPE in five aspects including breeding strategy,photosynthetic physiology,breeding methodology,breeding system and cultivar development,aiming at providing theoretical basis for increasing photosynthetic efficiency of C3 crop through the way of soybean breeding for HPE and promoting its progress.It may be a new way of improving soybean photosynthetic efficiency that starting up the C4 pathway in C3 crops,through integrating functions associated with HPE and combing with the conventional breeding.As result the methodology of soybean breeding for HPE could be determined.The photosynthetic and physiological basis of soybean HPE are that light and dark reactions are obviously improved compared with that of normal soybean cultivars.The breeding theory of soybean consists of crop genetic breeding theory and crop physiological principle.The theoretical basis of soybean breeding for HPE includes physiological genetics,photosynthetic physiology on specific crop eco-types.According to the methodology and theory of soybean breeding for HPE as well as breeding practice,the high yield breeding system on the base of HPE was established,and soybean cultivars with HPE,Heinong 39,Heinong 40 and Heinong 41 were developed.更多还原
