In: Pesquisa Agropecuaria BrasileiraSummary: Los rendimientos de grano de 11 cv. de frijol negro evaluados en el Estado de Espirito Santo, Brasil, en 15 ambientes diferentes, entre 1981 y 1983, mostraron diferencias ambientales de 1050 a 2717 kg/ha. La mayoria de los cv. presento una respuesta buena y similar al estimulo ambiental. Los mas productivos fueron BAT 304, Iguacu, Preto 60 dias y BAT 179, los cuales fueron aprox. 27, 12, 12 y 11 por ciento superiores al testigo Rio Tibagi (1280 kg/ha), resp. Solo BAT 304 mostro adaptabilidad general, mientras que los demas, tambien superiores, parecieron mostrar mayor adaptabilidad a mejores ambientes; los genotipos similares a 8017.1.1 no se adaptarian a ningun ambiente. Se obtuvo mayor estabilidad en rendimiento con BAT 304 e Iguacu, mientras que los mas inestables fueron ICA Huasano y 8017.1.1. En ensayos en fincas, BAT 179, BAT 304 e Iguacu, los mejores comercialmente para Espirito Santo, produjeron de 1600 a 2400 kg/ha, en las condiciones favorables de la estacion seca de 1983. Estos se liberaron como nuevos cv., oficialmente denominados Capixaba Precoce (BAT 304) y Vitoria (BAT 179) mientras que Iguacu se recomendo con el nombre original, en sept. de 1983. (RA-CIAT)Summary: Grain yield of eleven black bean cultivars tested in Espirito Santo State, Brazil, under fifteen varied environments, between 1981 and 1983, showed different environmental means from 1.050 to 2.717 kg/ha. The cultivars mejority presented a good and similar response to environmental stimulus. The most productives were BAT 304, Iguacu, Preto 60 dias and BAT 179, around 27 percent, 12 percent, 12 percent and 11 percent superior to the pattern, Rio Tibagi (1.280 kg/ha), respectively. Just BAT 304 had general adaptability, while the others, also higher, seemed to adjust greater adaptability to better environments; 8017.1.1 similar genotypes would be unadapted over all environments. Greater yield stability was got with BAT 304 and Iguacu, while the most unstable were ICA Huasano and 8017.1.1. In farming proofs, BAT 179, BAT 304, and Iguacu, the best commercially for the Espirito Santo, produced from 1.600 to 2.400 kg/ha, in 1983 dry season favourable conditions. They were released as new cultivars, officialy named Capixaba Precoce (BAT 304) and Vitoria (BAT 179) whereas Iguacu was recommended with the original name, in September, 1983. (AS)
