Abstract

We conducted a comparative study from 2008 to 2011 to study the adaptability and stability of grain yield of upland rice in two regions of Campeche, Mexico. The individual and combined statistical analysis, showed highly significant differences in grain yield of different genotypes in both regions. The experimental error variance was uniform, both effects of repetition/location and variety/location were highly significant. The results of analysis for grain yield stability parameters showed highly significant effects for 12 treatments, and significant for one. Eighteen genotypes showed a significant variation in the effects of deviation from the regression parameters of stability. The highest grain yield was observed in genotypes 25, 18, 21 and 2; there were no significant differences between them. However, due to the existence of significant differences in the deviation of the regression, the genotypes cannot be recommended for a particular region. The tendency of the smaller slope of the regression corresponded to genotypes 1, 2 and 5, which are the best suited to unfavorable growth conditions. In general, genotype 25 showed maximum adaptation and yield stability for the two regions evaluated in the state of Campeche.
