Abstract
Description
El presente estudio se llevó a cabo durante los años 1994 a 1997. Se evaluó la adaptación de la línea DOR-500 en ocho experimentos establecidos en el trópico húmedo de México, cinco en el Estado de Veracruz, dos en Chiapas y uno en Guerrero. La línea DOR-500 resultó sobresaliente por su rendimiento, amplia adaptación y estabilidad (1063 kg/ha,bi=1.0,S2di=0). Además, DOR-500 se estableció en parcelas comerciales en diez localidades del Sureste de México (climas tropical), en éstas DOR-500 se comparó con testigos regionales y locales, y obtuvo un rendimiento medio de 1327 kg/ha. La línea DOR-500 fue tolerante a las enfermedades mosaico dorado, (BGMV) mancha angular (Phaseoisariopsis griseola) y roya (Uromyces appendiculatus). La línea Dor-500 está en trámite para su registro, como nueva variedad para las regiones productoras del trópico húmedo de México.
The present study was carried out during 1994 to 1997. Adaptation of the DOR-500 line was evaluated in eight experiments established in the humid tropic of Mexico, five in the state of Veracruz, two in Chiapas and one in Guerrero. The line DOR-500 was excellent according of its yield, wide adaptation and stability (1063/ kg/ha, bi=1.0, S2di= 0). DOR-500 line was established in commercial plots in ten locations of the Mexican Southeast (tropical climate) comparing this line to the regional and local control treatments; it was obtained a yield of 1327 kg/ha. The DOR-500 line was tolerant to the bean golden mosaic virus (BGMV), Leaf spot (Phaseoisariopsis griseola), and rust (Uromyces appendiculatus). The Dor-500 line is being registered as a new variety for the production regions of Mexico.
