对非洲栽培稻 ( O.glaberrima steud.)的形态、生理和亚、非栽培稻种间育性的研究表明 ,非洲栽培稻叶舌短而圆 ,株高多为 80～ 1 0 0 cm,稻穗极少 2次分枝 ,柱头外露率高 ,地稻瘟病、纹枯病有较强抗性 ,感光性较强 ,在思茅夏季大部分不抽穗。亚洲栽培稻 ( O.sativa L .)与非洲栽培稻的杂交 1代育性较低 ,在 3 0 9个组合中 ,仅 1个组合结实率为 1 5% ,其余在 5%以下 ,育性主要由两亲染色体同源性的高低所决定 ,少数存在核质互作的影响 Studies on the morphology, physiology and fertility of O.glaberrima steud. From African and non-cultivated rice showed that the leaves of African cultivated rice were short and round, the plant height was mostly 80 ~ 100 cm, Spike rarely 2 branches, stigma exserted high, to rice blast, sheath blight have strong resistance, strong photosensitivity, most of the Simao summer is not heading. The crosses between O. sativa L. and O. sativa L. were less fertile in China. Only one of the 309 combinations had a seed setting rate of 15% and the rest below 5%. Fertility Mainly by the level of amphipathic chromosomes determined, a few have the impact of nuclear interactions
