The main priority of efforts in genetic improvement of beans is to increase the production in areas where it is currently cultivated. The environment in those areas has unfavorable climatic conditions for the crop and instead, favorable for the disease- insect complex attacking it. Through the co...
Eighty-three F2-derived F8 recombinant inbred lines (RILs) randomly selected from a population (TY 8419) of two common bean genotypes (Pinto UI 114 x ICA Pijao), the two parents, and a control cultivar (Topcrop) were screened for their reaction to bean golden mosaic virus (BGMV) under glasshouse ...
Methods used to identify BCMV are described in terms of symptomatology (common mosaic, black root); transmission (seed, insect, manual); responses of differential bean cv. (mosaic, systemic or local necrosis, local lesions, immunity); cytology (light and electron microscopy); purification and ser...
BCMV causes losses of up to 50 percent and produces mosaic and systemic necrosis on the plant. It is seed borne and several species of aphids are vectors; it is transmitted mechanically with relative facility. A description is given of the methodology used by CIAT to identify and manage the virus...
The genetics of resistance to bean golden mosaic virus (BGMV) was studied in an 8×8 complete diallel cross of common bean, Phaseolus vulgaris L. The 28F1 hybrids, their reciprocals, and eight parents were artificially inoculated with BGMV under glasshouse conditions. Data were recorded and analyz...
