| Research Abstract |
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.
