During 1986 screening of advanced bean lines for efficiency at low levels of P and for tolerance to high levels of Al saturation continued. A review of data from 8 yr. of screening indicated that the genetic variability of beans for these 2 characteristics is low. Furthermore, the data suggest th...

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 ...
