Value for cultivation and use of upland rice cultivars tested in multi-environments.
Data from 11 years of a breeding program for upland rice of the partner institutions Embrapa arroz e feijão, Epamig and UFLA conducted in 11 regions of Minas Gerais, were analyzed by the mixed model methodology. The genotypic correlations between environments ranged from medium to high, suggesting the predominance of simple interaction, but with differentiated ranking of genotypes at the different locations. Lines with specific performance, as well as lines of broad adaptation were identified. The performance of cultivar BRSMG Caravera, released in 2007, was superior to the others in terms of grain yield at all sites assessed, in other words, broad adaptation, in addition to a high genotypic performance
BRSMG Ouro Minas: cultivar de arroz para cultivo irrigado por inundação continua.
O cultivar BRSMG Ouro Minas, lançado pela EPAMIG e Embrapa Arroz e Feijão em 2001, para ser cultivado em Minas Gerais com irrigação por inundação continua e em várzeas úmidas, resultou do cruzamento das linhagens 17719,5738 e IR 21015-72-3-3-3-1, realizado pelo CIAT. Possui ciclo médio, atingindo a maturação com 135-140 dias de idade; alta capacidade de perfilhamento, porte médio (90cm) e resistência ao acamamento
