Family number in common bean selection

Potential of hypocotyl diameter in family selection aiming at plant architecture improvement of common bean.

Cultivars of common bean with more erect plant architecture and greater tolerance to degree of lodging are required by producers. Thus, to evaluate the potential of hypocotyl diameter (HD) in family selection for plant architecture improvement of common bean, the HDs of 32 F2 plants were measured in 3 distinct populations, and the characteristics related to plant architecture were analyzed in t...

Direct and Marker-Assisted Selection for Resistance to Common Bacterial Blight in Common Bean

Common bacterial blight (CBB) caused by Xanthomonas campestris pv. phaseoli and X. campestris pv. phaseoli var. fuscans is a seed-borne disease that can signifi cantly reduce yield and seed quality of common bean (Phaseolus vulgaris L.). Disease resistance is the most effective management strategy, but most common bean cultivars have no CBB resistance. Marker-assisted selection (MAS) shows prom...

Comparison of mass, F2-derived family, and single- seed-descent selection methods in an interracial population of common bean

OAC Rex common bean

Michaels, T. E., Smith, T. H., Larsen, J., Beattie, A. D. and Pauls, K. P. 2006. OAC Rex common bean. Can. J. Plant Sci. 86: 733–736. OAC Rex is an upright indeterminate bush white bean (Phaseolus vulgaris L.) cultivar intended for use in areas with greater than 2800 crop heat units. It has good yield potential in either wide or narrow row production. It is resistant to races 1 and 15 of bean c...

Dissemination Pathways of Common Bean

Dissemination pathways of common bean (Phaseolus vulgaris) cultivars from their areas of domestication to other parts of the Americas were determined using phaseolin type, as determined by 1-dimensional SDS/PAGE. Common bean cultivars of lowland South America exhibited approximately equal numbers of 'S' and "T' phaseolin types. "S" cultivars of that region may have been introduced along a route...
