Abstract:
... Soybean production in Brazil is concentrated in the central and southern regions of the country, although expansion is occurring toward the northeast, where semi-arid conditions are predominant. There is little information on the behavior of soybean cultivars in semiarid climates; therefore, the objective of this study was to evaluate the interaction of soybean genotypes by environment, adaptabili ...

Abstract:
... Legumes are important in sustainable agriculture and particularly so when they are intercropped with other species. In breeding programs, little attention is paid to their agronomic performance in species mixtures. In red clover, improved persistence is an important breeding goal. We identified traits associated with survival of red clover cultivated in pure stands (PS 3) or in mixtures with grass ...

This species is split into two genetic groups: Guinean and Congolese. Côte-d’Ivoire is the primary diversification center of the Guinean pool, which offers great potential for genetic improvement. However, genetic erosion of this group is curr ...
