Phaseolus beans are distributed worldwide and are cultivated in the tropics, subtropics, and temperate zones. The common bean is the most important grain legume for direct human consumption in the world. The objectives of this study were to isolate microsatellite repeats and to establish their di...

Assembled germplasm has provided breeders with valuable traits for the improvement of common beans. Molecular markers such as phaseolin and isozymes have facilitated understanding of the genus Phaseolus thus enabling breeders to develop more effective strategies. However, there are still gaps in ...

Nuñas are a group of common bean (Phaseolus vulgaris, Fabaceae) varieties, whose grains are consumed after toasting in their original Andean habitats. Nowadays, these varieties are restricted to certain parts of the highlands of Peru and Bolivia. Linguistic, ethnobotanical, and archaeological dat...

The cassava core collection was selected to represent, with minimum repetitiveness, the potential genetic diversity of the crop. The core (630 accessions) was chosen from the base collection (over 5500 accessions) on the basis of diversity of origin (country and geographic), morphology, isozyme p...

Restriction fragment analysis was used to determine the variation of chloroplast DNA (cpDNA) among and within different species of Passiflora. Total DNAs of 35 accessions, representing 12 species, were digested with four restriction endonucleases. Southern blots of the restriction digests were th...
