- NEGRO GRIJALVA, NUEVO CULTIVAR DE FRIJOL PARA EL TRÓPICO HÚMEDO DE MÉXICO Bernardo Villar Sánchez Ernesto López Salinas Oscar Hugo Tosquy Valle Agrociencias In the tropical areas of southeastern Mexico the small-opaque black bean class is the most demanded by growers and consumers. In 2003 the line DOR 445 was released as a new cultivar named "Negro Grijalva". This cultivar is of early maturity, resistant to BGYMV and adapted to acid soils. From 1997-2000 Negro Grijalva was compared to cv. Negro INIFAP across fifteen year-site combinations in the state of Chiapas under residual moisture conditions; the yield of Negro Grijalva was 1 219 kg ha-1, 35.9% higher than that of Negro INIFAP. In a soil of pH 4.3 in central Chiapas, the yield of Negro Grijalva was similar to Negro INIFAP and with the addition of lime at a rate of 1.5 t ha-1, its yield increased by 20.8% vs 6.0% in Negro INIFAP. Therefore, Negro Grijalva can be used in acid soils with or without the addition of lime by low income farmers. Negro Grijalva has a seed weight of 23 g per 100 seeds. 2009 artículo científico 0568-2517 https://www.redalyc.org/articulo.oa?id=60812263013 es http://www.redalyc.org/revista.oa?id=608 Agricultura Técnica en México application/pdf Instituto Nacional de Investigaciones Forestales, Agrícolas y Pecuarias Agricultura Técnica en México (México) Num.3 Vol.35
