Introducing and analysis of effect of G x E interaction for elucidation of limiting factor on rice production in west Africa

在西非几内亚，通过数年的品种竞争研究，分析了旱作水稻产量形成的限制因素以及环境和基因型相互作用。结果表明，影响产量的最重要因素是环境成熟度。在整个时期，一个地点，品种成熟率与产量的相关系数为r=0.743(P<0.001)，被高度接受。本研究认为，无论环境好坏，亚洲水稻与非洲水稻种间杂交后代中NERICA的WAB1159-2-12-11-2-4是为了在非洲水稻中心和西非传统栽培的冈比亚卡获得高产而开发的，这表明基因型对环境具有这样的适应性。

We analyzed the limiting factor of yield formation and the environment and genotype interaction of the rainfed lowland rice through the varietal competitive examination of several years in a model in Guinea of West Africa. As a result, the most important factor to the yield was a ripening ratio readiness of environment. For the entire period, a site, the coefficient of correlation between the ripening ratio of the variety and the yield became r=0.743(P<0.001), and was highly extremely accepted. It was indicating the genotypes such an adaptability to environment, thought that WAB1159-2-12-11-2-4 of the NERICA of interspecific hybridization progenies between Asia rice and Africa rice developed for the purpose of a high yield in Africa rice center and Gambiaka which has been cultivated traditionally in West Africa in this study regardless of the environmental good or bad.
