Genetic variance, heritability, and expected response from selection are useful in devising alternative methods and criteria of selection. The objectives of this study were to estimate these for seed yield and its components from 200 F2 populations involving 80 cultivars and lines of mostly small...

Genetic variance, heritability and expected response from selection for dry bean (Phaseolus vulgaris L.) yield and its components
The value of intra- and interracial populations in common bean (Phaseolus vulgaris L.) needs to be determined in order to create useful genetic variation for maximizing gains from selection, broadening the genetic base of commercial cultivars, and making efficient use of available resources. Five...

Characterization of agronomic traits and markers of recombinant inbred lines from intra-and interracial populations of Phaseolus vulgaris L.
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...

Una continua y mayor ganancia genética por selección en frijol común (Phaseolus vulgaris L.) depende de nuestro conocimiento de la organización de la diversidad genética útil y la habilidad para explotarla para todos los caracteres de valor agronómico, no sólo dentro de la especie P. vulgaris sin...
