Ciência Rural , 2004,
Abstract: Com o aumento da competitividade do setor produtivo, a pecuária leiteira brasileira busca, de todas as formas, sistemas de produ o que obtenham maior produtividade e menor custo. Entre as estratégias adotadas para tal fim, est o a melhoria da qualidade do rebanho e da forragem fornecida aos animais, de modo que estes expressem todo o seu potencial produtivo. A alfafa, conhecida pela excelente qualidade forrageira e boa palatabilidade, surge como boa op o. Entretanto, ainda há muito o que se trabalhar para a obten o de cultivares melhor adaptadas às condi es tropicais. Informa es teóricas sobre características de importancia forrageira s o necessárias para a orienta o dos programas de melhoramento. Nesse sentido, o objetivo deste trabalho foi estimar o coeficiente de repetibilidade para a produtividade de matéria seca de alfafa na regi o Sudeste do Brasil e determinar o número ideal de avalia es para a sele o dos genótipos superiores, por meio de quatro metodologias diferentes. Utilizaram-se dados de produtividade de matéria seca obtidos em quatro ensaios de compara o de cultivares de alfafa, conduzidos em diferentes regi es do Estado de Minas Gerais. Estimou-se o coeficiente de repetibilidade (r), para cada um dos ensaios, por meio dos métodos da análise de variancia (Anova), dos componentes principais com base na matriz de covariancia (CP-1) e de correla o (CP-2), e pela análise estrutural baseada na matriz de correla o. Observou-se que houve boa concordancia entre as diferentes metodologias de estima o do coeficiente de repetibilidade em todos os ensaios. A estimativa média de repetibilidade para produ o de matéria seca de alfafa nos quatro ensaios avaliados foi de 0,59, com coeficiente de determina o médio de 0,96. Constatou-se, também, que a realiza o de apenas quatro cortes, em média, foram suficientes para se conhecer o real valor genotípico das cultivares testadas, com 85% de confiabilidade.

Abstract: The paper presents the results of a study research that aimed to analyze the participation and representation of women in politics in a Goiás period of nearly three decades. Thus, the study presents an updated picture of female representation in Goiás. The data analyzed in the survey have revealed that, in Goiás, women are still underrepresented in political and parliamentary arena. The research findings are very similar to the national and international scene. Therefore, the underrepresentation of women in parliament is not represented only a regional phenomenon, but worldwide.
