Journal Article 1992

Autor: Sanginga, N. Mulongoy, K. Swift, M.

Research to identify appropriate means of sustaining tropical soil productivity has intensified during the last 2 decades and promising technologies such as minimum tillage, herbaceous and tree based systems, and improved fallows have been identified. This paper discusses the contribution of soil...

Cultivars and landraces of a crop species represent the primary gene pool available to plant breeders for improvement of crop plants. Knowledge of relative genetic relationships among genotypes is useful in a breeding program because it permits organization of germplasm resources. The genetic rel...

Cultivares y variedades criollas de una especie cultivada, representan la principal fuente de genes disponibles para el mejoramiento de cultivos. El conocimiento de la relación genética entre genotipos es útil en un programa de mejoramiento genético porque permite la organización del germoplasma ...

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...

In the 1986 breeding program for enhanced N fixation, emphasis was placed on small seeded indeterminate beans; however, at the beginning of 1986 it was decided that some priority should be given to materials for Africa, including larger seeded determinate and indeterminate bush types. In Popayan,...

En el programa de mejoramiento de 1986 para incrementar la fijacion de N, se dio enfasis al frijol indeterminado de semilla pequena; sin embargo, a comienzos de 1986 se decidio que se daria alguna prioridad a materiales para Africa, incluyendo los tipos arbustivos determinados e indeterminados de...

Ten new cassava genotypes selected for high yield and tolerance to some biotic stresses were evaluated alongside the local best, Otupam and ‘TMS 30572\' (a widely cultivated hybrid genotype, as an improved check) for two cropping seasons with a view to obtaining suitable genotype(s) that could be...

Autor: Winslow, M.

Silicon deficiency limits rice (Oryza sativa L.) yield on highly weathered upland soils in West Africa and can increase susceptibility to some diseases. A study at Onne, Nigeria, examined responses of different genotypes to increasing Si supply under upland cultural conditions. Without applied Si...
