A total of 23 genotypes belonging to seven tropical food yams and two wild relative species of different origin and coming from two sampling ecological zones (the Republic of Benin in Africa and Guadeloupe in the Caribbean) was analysed for their 13C content. The δ13C values for all yam samples (...

Cassava (Manihot esculenta Crantz) is a staple food for over 600 million people in the tropics and sub-tropics and is increasingly used as an industrial crop for starch production. Cassava has a high growth rate under optimal conditions but also performs well in drought-prone areas and on margina...

Research of the physiology section was centered on identifying the characters associated with high root yields and quality in cassava under stress conditions. Plant reaction to water stress was studied, specifically regarding growth and yields of var. M Mex 59 and M Col 22 with a period of artifi...
El enfasis de las investigaciones de la seccion de fisiologia se centro en la identificacion de los caracteres asociados con un alto rendimiento y calidad de las raices en condiciones de estres. Se estudiaron las reacciones de la planta a la sequia, especificamente el desarrollo y los rendimiento...

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...

During 1981 the physiology section of CIAT's Cassava Program emphasized the understanding of factors that contribute to yield under stress conditions. Regarding photoperiodic effects, long days (16 h daylength) decreased HI and root yield while increasing total DM and the no. of apices/plant in c...
