摘要
以提高C3作物大豆光能利用率实现培育超高产大豆新品种的目标为主线,以能量论观点推算大豆产量界限,提出中国大豆超高产育种目标,并从大豆生物量、表观收获指数、生育期、花荚脱落性状、超高产理想株型育种及高光效育种等方面叙述了与超高产大豆育种相关研究的新进展。认为培育和推广超级豆是继有性杂交育种之后,提高大豆综合生产能力,实现大豆产量突破和产业发展的重要途径,超高产理想株型育种和高光效育种是大豆超高产育种的重要途径和方法之一。同时对中国大豆超高产育种的关键科学问题进行了探讨。
This paper focused on improving the utilization efficiency of solar energy in C 3 crop of soybean for obtaining super high-yielding soybean cultivars .The relative upper limit of soybean yield potential was estimated according to the energy transformation theo -ry and then the super high-yielding objectives for various eco-regions in China were set for yield contest program.For achieving the goals, the advances in wide areas related to breeding for super high-yielding soybean, including soybean biomass accumulation , ap-parent harvest index , growth periods , flower and pod abscission , ideal plant types and photosynthetic efficiency were reviewed to pro-vide a comprehensive understanding on the elements of super high-yielding cultivar development.It is proposed that breeding for ideo-type and high utilization efficiency of solar energy is the basis for achieving yield breakthrough in soybean industry with the improved field cultivation and management technology.In addition , the important scientific issues regarding further study on breeding for super high-yielding cultivars were discussed in the present paper.
