摘　　要：亚洲栽培稻分为籼与粳两个亚种,籼与粳之间在形态指标和生理机能方面存在诸多不同,在长期的历史演化中分分合合,颇为传奇。本文就其形态与基因型区别、地理分布、历史演化、籼粳桥梁基因、籼粳杂交育种、亚种间杂种优势利用等方面进行概述和探讨,期望对籼粳融合的现代籼粳亚种间杂交稻育种与关键基因发掘引起重视。There are two kinds of subspecies included Xian(Oryze sativa subs.indica)and Geng(Oryza sativa subs.japonica)in Asia cultivated rice,and so many different characteristics and physiological functions existed obviously between them.Xian and Geng divided and united several times in long evolution history,like a legend.This paper mainly describes and discusses the difference of phenotype and genotype,geographical distribution,history evolution,wide compatibility bridge gene,crossbreeding between Xian and Geng subspecies,utilization of heterosis of Xian and Geng subspecies,and so on.It is expected to paying attention to the breeding of Xian-Geng hybrids and the discovery of keynote integrated genes.
