以携带野生稻高产QTL的晚稻新恢复系远恢611所配部分强优势组合为材料，对其部分光合生理指标进行测定的结果表明，远恢611系列组合杂种优势强，穗大粒多，库容量大，具有超高产潜力；后期上面3片功能叶宽大、直立、叶面积大，与茎秆夹角小，不披垂；比叶重大而稳定，不早衰；剑叶净光合速率高，库很大且源较足是远恢611系列组合高产的主要生理原因；也可能是野生稻高产QTL高效表达的重要生理基础。

Some photosynthetic characteristics of the hybrids derived from Yuanhui 611, a new late-season indica hybrid rice restorer line which contains two yield-enhancing quantitative trait loci （QTL） alleles yldl. 1 and yld2.1 from Oryza rufipogon Griff., were surveyed with Weiyou 64, an elite hybrid rice combination derived from Ce 64-7, the acceptor of yield-enhancing QTL and the original parent of Yuanhui 611, as check. The hybrids of Yuanhui 611 showed strong heterosis, such as big panicle with many spikelets, large sink size and super high-yiel...
