The bean pod weevil (Apion godmani Wagner) is a serious insect pest of common beans (Phaseolus vulgaris L.) grown in Mexico and Central America that is best controlled by host-plant resistance available in Durango or Jalisco genotypes such as J-117. Given unreliable infestation by the insect, the...

Plant-to-plant phenotypic variation has been observed within accessions of S. capitata maintained at the Centro Internacional de Agricultura Tropical (CIAT) since shortly following introduction. A small experiment was conducted to determine the potential importance of natural outcrossing as a cau...

Seed multiplication, agronomic evaluation, and identification of parental genotypes for interspecific hybridization with Phaseolus vulgaris constitute the main research activities carried out in the P. coccineus collection (around 1600 accessions) held by CIAT. In 1985, 3 Ascochyta screening tria...

The bean weevil Acanthoscelides obtectus, is an important storage pest of common beans in Latin America and Africa. A few wild bean accessions from Mexico have been identified as highly resistant to the weevil. One accession, G 12952, was crossed to two susceptible bean cultivars differing in see...

The effect of visual screening for grain yield was studied in 9 bean populations resulting from 3 different crossings (single, 3- way, and modified-double crosses) involving different groups of genetic pools from Central America and the Andes. The best yielding lines in the F2 and F3 generations ...

Nineteen early maturing, indeterminate common bean parents were crossed with a tester line of normal maturity. All parents, F1 hybrids, F2's, and backcross generations were evaluated at CIAT-Palmira, Colombia. All 19F1 populations flowered and matured almost as early as the respective early paren...

Con el objetivo de analizar el flujo de genes entre frijol común silvestre y cultivado, se determinó el porcentaje de alogamia en condiciones naturales de crecimie nto del frijol silvestre y en estación experimental. En el 2004 se evaluó el cruzamie nto natural entre frijol silvestre mexicano G23...
