摘要
从我国杂交水稻的推广、杂种优势的普遍性、籼粳亚间杂种优势利用、光(温)敏雄性不育性、广亲和基因的利用价值等方面讨论了北方粳稻杂种优势利用的现状与问题;认为从物质积累与能量转化角度探索超高产的可行途径是今后杂交水稻和常规水稻育种研究的共同课题。
Based on Literature available and from the aspects of extension of hybrid rice in China,univer- sality of heterosis,utilization of heterosis between indica and japonica,value of wide compatibility gene,and photoperiod sensitive male sterile,discussion was made on the present condition and problem existed of the u- tilization of heterosis of japonica rice in northern China rice growing regions.The result suggested that it is the same subject of breeding rice for hybrids and conventional cultivars to explore the valuable ways for super high yield from the point of view of dry matter assimilation and energy transition.
