摘要
我国于1996年启动了理想株型与亚种间杂种优势相结合为技术路线的超级稻育种计划,目前已育成约80个超级稻品种。这些品种产量高,兼顾品质与抗性,在试验示范区或特定气候条件下产量可达到12~21t/hm2,展示了超级稻的巨大增产潜力。对于超级稻品种高产的原因,可概括为以下几个方面:与常规高产品种相比,超级稻品种每穗颖花数多、库容量大(即单位面积颖花数多);叶面积指数大、绿叶面积持续期长、光合速率高、茎秆抗倒性强;抽穗前干物质累积量高,结实期茎叶中碳水化合物转运到籽粒中的量大;根量大、根系活性强。但是,超级稻品种在生产上也存在一些问题,突出地表现在两个方面:一是强势粒(着生在穗子中上部、开花较早的籽粒)、弱势粒(着生在穗子基部、开花较迟的籽粒)充实整齐性差;二是结实率低且不稳定。综述了超级稻的生物特性、产量结构、群体质量特征以及相关生理机理方面的研究进展,提出深入开展超级稻栽培生理研究的建议。
