Low phosphorus availability is a primary constraint to crop production in developing countries. Adventitious roots play an important role in phosphorus acquisition, as they are localized near the soil surface where phosphorus is relatively abundant. A population of recombinant inbred lines of Pha...

Evaluation of natural Stylosanthes germplasm leading to the release of 8 commercial cultivars began in South America in the late 1960s and early 1970s. Perceived deficiencies in existing germplasm, including anthracnose susceptibility, led to the initiation of Stylosanthes breeding projects as ea...

The objective of this study was to estimate the results of the upland rice (Oryza sativa L.) breeding program conducted by the Brazilian Agricultural Research Corporation (Embrapa) and collaborators over the period of 1984 to 2009 covering 25 annual steps of improvement. The best lines generated ...

A literature review is presented of the different concepts related to biological N fixation (BNF) in beans as well as the procedures to establish breeding programs leading to increase BNF. The N requirements of bean plants are determined as well as the sources from which it can be obtained; the b...

In recent years, increasing numbers of pathogens and pests have been reported from major centres of tropical pasture research. Damage is often severe and controls are needed. Diseases and pests may be controlled chemically, biologically, culturally and genetically. In pasture plants genetical res...

Varietal selection is particularly difficult for very heterogeneous environments where farmers have a range of preferences. To address these issues in Rwanda, local bean experts, generally women, are invited to the research station to assess cultivars and to select those they prefer for their plo...

More than 60 accessions of tepary bean (Phaseolus acutifolius) and five cultivars of common bean (P. vulgaris) were evaluated for disease reactions to different races of wilt-causing Fusarium (F. oxysporum f. sp. phaseoli) under glasshouse conditions; 95% of the tepary accessions were resistant. ...
