Abstract:

Over the two cultivated rice species, Oryza glaberrima Steudt. is a source of useful genes for important traits that do not exist in Asian rice which belong to species Oryza sativa L. This resistance gene deficiency in Asian rice has limited his performance in Africa. This has greatly inspired interspecific hybridization process between the two cultivated rice species in order to promote a new type of rice better adapted to constraints and production conditions of African farmer. To improve genetic diversity of rice grown in irrigated conditions, performance evaluation of 31 intra- and inter-specific lines was carried out on two sites for two seasons. Analysis of variance on combined site and season showed significant Genotype effect on all characters studied. Significant effect of Season on Plant duration and interaction Genotype x Location (G x E) on Plant height was observed. No G x E effect on grain yield was observed. Overall average Grain yields vary between 6.6 and 8.8 t ha -1 . Positive correlation between Plant height and Grain yields was observed and higher Grain yields were obtained by medium to long duration lines. Based on average yields on Locations and Seasons combined or not, three groups of lines were observed.
