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...

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 ...

Activities carried out by the Instituto Colombiano Agropecuario (ICA)-CIAT collaborative project on beans for cold climates in ICA`s regional center in Obonuco and in the dept. of Narino (Colombia) are reported. On the exptl. farm, 6233 materials were evaluated in bush bean trials, of which 103 w...

Close collaboration between CIAT and Brazil continued during 1986. Germplasm development was conducted through evaluating the jointly developed crosses in Brazil, rather than selecting the fixed lines in CIAT prior to shipment to Brazil. By the end of 1986, those segregating populations were in t...

La colaboracion estrecha entre CIAT y Brasil continuo durante 1986. Se realizo desarrollo de germoplasma a traves de la evaluacion de los cruzamientos desarrollados conjuntamente en Brasil, en lugar de seleccionar las lineas fijas en CIAT antes de su envio al Brasil. Hacia finales de 1986, estas ...
