Desempenho agronômico de cultivares de café resistentes à ferrugem no estado de Minas Gerais, Brasil
[Agronomic performance of coffee cultivars resistant to coffee rust in Minas Gerais state, Brazil]
Bragantia 71 (4), 481-487
Abstract: The purpose of this study was to evaluate the agronomic performance of 24 coffee cultivars (22 rust resistant cultivars and 2 susceptible control varieties) in different environments of Minas Gerais State, Brazil. The coffee plants were planted in four locations (Lavras, Campos Altos, Patrocínio and Turmalina) in three agroclimatic regions. The experiments were arranged in randomized complete block design, with three replications in plots measuring 3.5x0.7 m, with 10 plants per plot. The following traits were analyzed: yield, percentage of grains retained in sieve size 16 and vegetative vigor from four cropping years (2008 to 2012) and the adaptability and stability in yield. The cultivars showed differential performance in the four environments. The cultivars Sabiá Tardio, Pau Brasil MG1, Obatã IAC 1669-20, Catucaí Amarelo 24/137 and IPR 103 were the most promising because they combined higher agronomic stability and adaptability in favorable and unfavorable environments.
