A detailed socio-economic description is given of this rustic farm community on the Atlantic Coast of Colombia. Where cassava is the main source of income. Av temp is 28 degrees Celsius, annual rainfall 1556 mm; the sandy soils (pH 5.5-6) have less than 1 percent OM, less than 15 ppm P and less t...
Crosses were made and cv. and lines selected to combine the existing resistance to Xanthomonas campestris pv. phaseoli with adaptation to the tropics and to determine new sources of resistance. Crosses were made between adapted lines and sources of resistance, some with Great Northern genes. The ...

The process of selection in climbing bean improvement should be conducted with maize in association due to the high cost of sole cropping with stakes or with a trellis system. The relation between yields of beans and maize is negative and the regression coefficient is normally between -1 and -2. ...

The low digestibility of grain legumes, particularly beans, is highlighted and its regulating factors (tannins, seed coat fiber, protease inhibitors, protein structure of the protein to digest, interactions between proteins and other cotyledon nutrients, etc.) are explained with the aid of a line...
All commercially grown bean var. in Central America of small shiny red grain type are susceptible to one or more strains of BCMV. An attempt was made to recombine the important var. characteristics of var. such as Honduras 46, Rojo Zamorano, Nahuizalco, Rojo de Seda, and Desarrural, in addition t...

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...

The progress and partial results are given of the research on the variability of protein and met. contents in beans. Crosses were made between 3 PI lines and Bush Blue Lake 240 (BBL 240), using the latter as female parent. The resulting generations were grown in Wisconsin, USA (1972) in a complet...

Results of a study on bean cultivation in El Salvador are given. Aspects analyzed were as follows: consumption structure (apparent, per capita, and rural-urban; preferences, consumption and cooking ways, and nutritive value); area, production, and yields (at national and regional levels, by cropp...
