Resumo: | This work was developed with the objective of evaluating and selecting alfalfa genotypes using methods of adaptability and phenotypic stability, for the production of dry matter in harvests during the rainy and drought seasons. The experiment made use of 92 alfalfa genotypes, conducted in three environments, in randomized blocks with two replications. For analyses of the adaptability and stability of the materials, the three methods applied were the traditional methodology, the Eberhart and Russel method, as well as the centroid method. The results using the traditional method of analysis indicate that the genotype WL 612 presents the lowest variation; however, as it features low averages of dry matter production, it is not recommended for such use. Applying the Eberhart and Russel methodology, LE N 4 had the best adaptability of dry matter production. Using the centroid method, several genotypes displayed overall adaptability; however, LE N 4 and P 30 were closest to centroid 1. The genotypes with the best behaviors in wet environments were Rocio and Costera SP INTA and, in the drought period, Bacana performed the best. Genotype LE N 4 showed the best overall adaptability, and genotype Bacana can be an option for utilization in the drought period. |

O experimento consistiu-se da avaliação de 92 genótipos de alfafa, conduzidos em três ambientes, em blocos ao acaso, com duas repetições. Utilizou-se a metodologia tradicional, de Eberhart e Russell e do Centróide. O método tradicional indicou o genótipo WL 612 como de menor variação, porém, como sua produção de matéria seca foi baixa, não é interessante sua utilização. A metodologia de Eberhart e Russel indicou que LE N 4 teve melhor adaptabilidade na produção de matéria seca. O método do Centróide indicou vários genótipos como de adaptabilidade geral, destacando-se LE N 4 e o P 30 como mais próximos do centróide 1. Os genótipos de melhor comportamento, no ambiente das águas, foram Rocio e Costera SP INTA e, no período das secas, Bacana. Dos 92 genótipos analisados, 25 foram classificados como passíveis de descarte. O genótipo LE N 4 foi o de melhor adaptabilidade geral, e o genótipo Bacana pode ser uma opção para utilização no período das secas.Universidade Estadual de Maringá2008-05-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/351110.4025/actasciagron.v30i3.3511Acta Scientiarum.
