The method of selection used by CIATs climbing bean program is between the pedigree method (lineage) and the bulk population method. This method reduces the variation of each hybrid population in F, by individual selection. The evaluation of the germplasm bank was conducted in Popayan (1850 m abo...
Des études antérieures ont prédis que le maïs deviendra une culture commerciale et assurera la sécurité alimentaire mieux que toute autre culture. Dans le Nord du Bénin par exemple, il vient en deuxième position après le coton en tant que culture de subsistance et de rente. Selon le Ministère de ...

The genetic changes occuring in av. productivity, adaptation, and response to environments with different levels of yield for black-colored grain material selected by CIAT during 1976-79 are examined. Data from 124 expt. of the International Bean Yield and Adaptation Nursery (IBYAN) of black bean...

In hot, humid areas some 40 percent of stored grain in lost; however, control of RH generally requires expensive equipment. The objectives of this expt were to evaluate the behavior of bean seeds of different size, color and moisture content at different levels of RH and to correlate adsorption a...

The improvement strategy of climbing bean in Cusco should take into account the importance of maize as a crop. In a recent study in 2 maize-growing communities of Valle Sagrado, 75 and 88 percent of the farmers considered beans as the main crop; however, only 57 and 22 percent of the maize-growin...

The International Bean Rust Nursery (IBRN) is in charge of testing promising Phaseolus vulgaris cv. and lines for their resistacne to rust (Uromyces phaseoli). In 1975-76 132 bean lines were tested, among which there were 28 potential rust-race differentials. In 1977-78, 26 trials were planted wi...
