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.
