BEAN GENOTYPE SELECTION FOR YIELD AND RESISTANCE TO GOLDEN MOSAIC VIRUS AND ACID SOILS

Abstract

In order to select genotypes of bean (Phaseolus vulgaris L.) for high yield and resistance golden mosaic virus and acid soils, a uniform experiment of 16 genotypes was established in 15 environments of the region known as Central Depression of the state of Chiapas during the period 1997-2000. Yield and stability of yield were evaluated and supplemented with a selection for resistance to golden mosaic virus and acid soils. Significant differences for environments, genotypes and their interaction found. Genotypes DOR 445 and DOR 454 were identified for their high yield and resistance to golden mosaic virus and acid soils, therefore they have potential to be liberated as new commercial varieties.
