东乡野生稻属普通野生稻,是迄今金世界分布最北的野生稻。东乡野生稻具有分蘖力强、光合作用强、耐寒、耐旱、休眠期长、柱头外露、花药长大、茎秆较细、璧较厚、较硬、叶片窄且较硬、异交结实率高、根系发达、叶片衰老较慢、米质优、抗病虫性较好等特点。分析了东乡野生稻与籼、粳稻的同工酶、染色体组型及亲和性,但是,东乡野生稻是籼或粳还有待进一步研究,对东乡野生稻与栽培稻杂交后几个性状的遗传力进行了测定。
Dongxiang wild rice is a wild rice, so far the distribution of the world’s northernmost wild rice. Dongxiang wild rice has strong tillering ability, strong photosynthesis, cold, drought, long dormant period, stigma exposed, anthers grow up, thin stems, thicker, harder, narrow blade and harder, outcrossing seed set rate High, developed root system, leaf senescence slower, high quality rice, good resistance to pests and diseases. The isozymes, chromosome constitution and affinity of Dongxiang wild rice and indica and japonica were analyzed. However, Dongxiang wild rice is indica or japonica, which needs to be further studied. The inheritance of several traits of Dongxiang wild rice and cultivated rice Force was measured.
