When appropriately scaled for mature size there were no sex or breed differences on growth rate. At the same estimated degree of maturity, there were no differences between the genotypes in fatness. An increased feed bulkiness reduced energy intake and led to leaner carcasses. The bulkier food (BULK) became less limiting to growth relative to the non-limiting feed (HIGH) as the lambs grew. This is as expected as relative nutrient demands decrease in animals as they approach their mature live weight and they ate more. |

Cotton produces one of the most important textile fibers of the world and has great relevance in the world economy. It is an economically important crop in Brazil, which is the world's fifth largest producer. However, studies evaluating the genotype x environment (G x E) interactions in cotton are scarce in this country. Therefore, the goal of this study was to evaluate the G x E interactions in two important traits in cotton (fiber yield and fiber length) using the method proposed by Eberhart and Russell (simple linear regression) and reaction norm models (random regression). Eight trials with sixteen upland cotton genotypes, conducted in a randomized block design, were used. It was possible to identify a genotype with wide adaptability and stability for both traits. Reaction norm models have excellent theoretical and practical properties and led to more informative and accurate results than the method proposed by Eberhart and Russell and should, therefore, be preferred. Curves of genotypic values as a function of the environmental gradient, which predict the behavior of the genotypes along the environmental gradient, were generated. These curves make possible the recommendation to untested environmental levels. |
