用六项形质综合评分法可将广西稻种区分为籼粳两亚种。其中有籼粳形质交错的品种,但不足以成为独立于籼粳之外的类型;交错现象随不同形质和品种类型而异,可能是在演化过程中进化不完全或不同步的结果,对稻种进化演变、亚种间杂种优势利用等研究及耐寒抗逆种质选育有价值。研究还证明,广西存在陆籼和早粳;广西深水稻属籼亚种,分类地位应与水、陆稻并列;广西光壳稻属粳亚种,虽有一定特殊性,但不足以成为一独立生态型。
The six-species comprehensive grading method can be used to distinguish two rice varieties of indica and japonica in Guangxi. Among them, there are indica-japonica varieties interlaced, but they are not enough to be independent of indica-japonica type. The interlacing phenomenon varies with different types and types of breeds, which may be the result of incomplete or asynchronous evolution in evolution. The evolution of rice evolution, the utilization of heterosis between subspecies research and resistance to cold resistant germplasm breeding valuable. The study also proved that there are indica rice and early japonica rice in Guangxi; indica-subspecies of Guangxi deep-rooted rice belongs to the classification status of water and paddy rice; Guangxi japonica subspecies japonica subspecies is not enough to be one Independent eco-type.
