Variability in the Nutritive Value of Three New Lima Bean (phaseolus Lunatus L. Walp.) Breeding Lines

Chemical composition and protein quality of raw and heat-processed (boiled and autoclaved) samples of selected advanced breeding lines of lima beans (Tpl 1, Tpl 7 and Tpl 175), part of a larger collection developed by the International Institute for Tropical Agriculture (IITA), and evaluated in agronomic field trials in Nigeria, were studied. Protein quality was evaluated using weanling albino ...

Diallel analysis to choose parents for black bean (Phaseolus vulgaris L.) breeding.

In this study, conducted in two different seasons, we aimed to choose parents to obtain promising segregating populations for the extraction of black bean (Phaseolus vulgaris L.) lines that are superior in terms of disease resistance, plant architecture, and grain yield. Twelve parents were arranged in two groups to compose a partial diallel in a 5 x 7 scheme. Group 1 was composed of parents wi...

Establishing the Bases for Introducing the Unexplored Portuguese Common Bean Germplasm into the Breeding World

Common bean (Phaseolus vulgaris L.) is among the most important grain legumes for human consumption worldwide. Portugal has a potentially promising common bean germplasm, resulting from more than five centuries of natural adaptation and farmers' selection. Nevertheless, limited characterization of this resource hampers its exploitation by breeding programs. To support a more efficient conservat...

Use of interracial hybridization in breeding the race Durango common bean

Backcross breeding for improved resistance to common bacterial blight in pinto bean (Phaseolus vulgaris

Common bacterial blight (CBB) caused by Xanthomonas campestris pv. phaseoli reduces common bean (Phaseolus vulgaris L.) yield and quality worldwide. Genetic resistance provides effective disease control; however, a high level of resistance is difficult to attain and does not exist in pinto bean, the most important dry bean market class in North America. Our objective was to determine if a backc...
