Pythium spp, cause severe bean root rots under cool and humid conditions. Poor soils and intensive cultivation compound the epidemics.
There are more than 120 species reported globally some of which are very pathogenic meanwhile others are saprophytic.
Yield losses due to Pythium outbreaks can be...

Molecular markers are Specific fragments of DNA that can be identified within the whole genome. In a genetic cross the characteristic of interest will stay linked with the molecular markers allowing for selection. Markers have the advantage of speeding up the selection process since analysis can ...

Background
Gender-related constraints reflect gender inequalities in access to resources and development opportunities. Access to productive assets is a major issue in the gender empowerment discourse. Despite the significant roles women play in agriculture and food security in many developing c...

This initiative was aimed at demonstrating that the public‐private partnerships in the bean seed value chain can make a difference to avail bean seed of improved varieties to farmers. The common beans is an import food crop covering an estimated area of 260,000 ha in Malawi in 2010. However the r...

Angular leaf spot (ALS) is one of the most devastating diseases of common bean (Phaseolus vulgaris L.) and causes serious yield losses worldwide. ALS resistance is reportedly pathotype-specific, but little is known about the efficacy of resistance loci against different pathotypes. Here, we repor...

Symbiotic nitrogen fixation (SNF) contributes to improve grain yield under nitrogen (N) deficiency. Climbing beans are known to be superior to bush beans in their potential for SNF. The main objectives of this study were to: (i) quantify genotypic differences in SNF ability of climbing beans usin...
