 ABSTRACT

The study was to evaluate yield components for submergence tolerance rice lines using AMMI model analysis across 6 locations in Nigeria. The genetic materials used were Four O. sativa genotypes conferred with submergence gene.  Three commercially released rice varieties (FARO 44, FARO 52 and NERICA L-19) and one local cultivar from each location of trial were inserted appropriately as checks. The trial was conducted in a Randomized Complete Block Design with 3 replications. Grain yield was analyzed using additive main effects and multiplicative interactions (AMMI). Result showed that ART 350:10-2-1-B-12-B and ART 351:12-2-B-5-B outperformed most of the check varieties in the agronomic parameters. Although, the genotypes showed no significant difference, the environmental effects were significantly different at 5% probability level. Principal components (PC) 1 and 2 also showed significant difference and contributed a total of 89.73% (59.35% and 30.38% respectively) of the total observable variation. The AMMI model deployed indicated that the largest proportion of the total variation in the rice grain yield for the genotypes studied under submergence condition was attributed to the environment. While Gwagwalada and Kaduna proved to be the best environments under study, the mean grain yield over environments indicated that ART 350:10-2-1-B-12-B and ART 351:12-2-B-5-B recorded the highest value of 3.9 and 3.8 tons/ha respectively.

Key words: Rice, AMMI, Interaction, Stability, Yield components.
