A busca por novos genótipos aliados a boas características agronômicas tem sido o principal foco dos programas de melhoramento do cafeeiro no Brasil. No presente trabalho objetivou-seselecionar progênies de Coffeaarabica L., em relação à adaptabilidade e estabilidade fenotípica da produtividade, para identificar os genótipos de melhor comportamento frente às variações ambientais. O experimento foi instalado em janeiro de 2007, nos Campos Experimentais da EPAMIG, nos municípios de Machado-MG e São Sebastião do Paraíso-MG. Foi avaliada a produtividade das progênies em sacas por hectare de 2009 a 2015 e nas colheitas de 2013, 2014 e 2015, foram avaliadas características agronômicas relacionadas ao rendimento: determinação de renda, rendimento e análise de peneira. O delineamento experimental foi em blocos casualizados, com quatro repetições e parcelas constituídas por 10 plantas. As progênies 107-47-02 Cova 1 e H 105-01-39 Cova 1 apresentaram melhor comportamento frente às variações ambientais, podendo ser utilizadas para o avanço de gerações no programa de melhoramento.
Brazilian coffee cultivation was boosted over the last few decades by the mechanization of various field operations. Considering the influence of genetic factors on coffee harvesting efficiency, we aimed to evaluate the use of mechanized harvesting characteristics as a criterion to select progenies derived from 'Icatu' germplasm, previously evaluated for agronomic characteristics, resistance to rust and cercosporiosis. We also investigated genotypic and phenotypic correlations between semi-mechanized harvesting characteristics. Ten progenies of Coffea arabica L. were analyzed in two experimental farms during two consecutive harvests. Genetic parameters were evaluated to trace selection strategies. Four progenies that were suitable for mechanization were selected, supporting our hypothesis of the use of harvest characteristics as selection criteria.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
