摘　　要：籼粳稻杂交后代易产生超亲变异和优势,蕴藏着巨大的遗传潜力。水稻产量的进一步提升寄希望于籼粳亚种间杂种优势的直接利用,但实现这一目标还面临着许多困难,解决途径有赖于对籼粳分化与杂种优势机理的深入研究。对亚洲栽培稻的起源与分化、籼粳稻分类的方法与评价、籼粳稻杂交育种的历史、存在的主要问题与解决途径、籼粳分化程度与杂种优势的关系、籼粳稻杂交后代中亚种特性与经济性状的关系及生态环境对籼粳交后代的影响等方面的研究进展进行了回顾与展望,为超级稻选育中籼粳亚种间杂种优势的直接利用提供科学依据与参考。Indica and Japonica rice hybrids easy to produce ultra-parents variations and heterosis, with vast reservoir of genetic potential. The rice yield further enhance hopes on the direct use of the subspecific heterosis, but achieving this goal still faces many difficulties, solution depends on the in-depth study of the mechanism of indica and japonica differentiation and hybrids heterosis, It was reviewed and prospected that origin and differentiation of Asian cultivated flee, classification methods and evaluation of the indica and japonica, history of hybrid breeding between indica and japonica, the main problems and solution in hybrid breeding between indica and japonica, the relationship between degree of differentiation of indica and japonica and heterosis of cross between indica and japonica, the relationship of subspecies characteristics and economic characters and the effects of ecological environments on the filial generation of cross between indica and japonica flee, to provide a scientific basis and references for direct use of the heterosis of cross between indica and japonica subspecies in super rice breeding.
