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… More >
