Abstract/Description

Primary emphasis is being placed on a search for genotypes with erect architecture adapted to narrow row spacings and high populations and which show marked yield increases under intensive agronomic management. This research strategy is complemented by studies on specific problems such as exploitation of late maturity; effects of seed size on tissue cell size, drought tolerance, and leaf photosynthetic rates; and possible inefficiencies in pollination. The results are included in table form. (CIAT)


Se ha dado enfasis fundamental a la busqueda de genotipos con arquitectura erecta, adaptados a espacios estrechos entre hileras y altas poblaciones y que muestren incrementos notables en rendimiento bajo manejo agronomico intensivo. Esta estrategia de investigacion se complementa con estudios sobre problemas especificos tales como explotacion de la madurez tardia; efectos del tamano de la semilla en el tamano celular de los tejidos, tolerancia a la sequia y tasas fotosinteticas foliares; y posibles ineficiencias en polinizacion. Se incluyen los resultados tabulados. (CIAT)
