Avaliação e seleção de progênies resultantes do cruzamento de cultivares de café Catuaí com mundo novo

Abstract

The objective of this paper was to select coffee progenies from the crosses of Catuaí with Mundo Novo , the most productives and adapted to different environment. In this experiment twelve progenies were selected, in the fourth generation for the second self-backcrossing of the Catuaí and Mundo Novo, developed by EMPRESA DE PESQUISA AGROPECUÁRIA DE MINAS GERAIS, Coffee Breeding Program. The coffee cultivars Catuaí Vermelho IAC-99, Rubi MG 1192 and Acaiá Cerrado MG 1474 were also as control. The experiments were conducted in São Sebastião do Paraíso and Três Pontas in Minas Gerais using the randomized block design, with four replicates and six plants per plot. There were evaluated the production based in the 60 kg bag of processed coffee/ha. The variance analysis was realized with split plot where each harvest (year) was considered as one split plot. The production data by place was analysed together, considering all the harvest. The treatment means were compared by Scott-Knott test, at 5% of probability. The results obtained showed that the best progenies were H 1190-11-70-2, 1190-11-119-1, 1190-11-70- 1 and 1190-11-8-2 and the progenies H 1190-11 -70-1 and 1190-11-8-2 had the highest adaptability on two environments.
