During 1986 emphasis was given to testing promising bean germplasm for yields and the 1st materials bred at CIAT specifically for drought tolerance. Preliminary screening was performed under mild stress in the 1st semester, while exceptionally dry weather permitted evaluation under high levels of...

Durante 1986 se dio enfasis a pruebas de germoplasma promisorio de frijol por rendimiento y de los primeros materiales mejorados en CIAT especificamente por tolerancia a la sequia. La seleccion preliminar se efectuo en condiciones de estres leve en el primer semestre, en tanto que condiciones de ...

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 exploit...

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 sob...

Results of 2 on-farm trials carried out in Peru during 1986 are presented in table form. In 1 of the trials, drought-tolerant bean var. were evaluated with 1 and 2 irrigation treatments. In the other trial, potentially rust- tolerant var. were evaluated at 2 plant densities. For drought condition...

Se presentan los resultados en forma de tabla de 2 ensayos realizados en Peru durante 1986. En un ensayo se evaluaron var. de frijol tolerantes a la sequia con 1 y 2 riegos. En el otro se evaluaron var. potencialmente tolerantes a roya a 2 densidades de siembra. Para sequia las var. promisorias f...
