Analysis of DNA polymorphisms allows for the genetic identification and precise discrimination of species with a narrow genetic base such as common bean. The primary objectives of the present study were to molecularly characterize commercial common bean varieties developed at various research institutions using microsatellite markers and to determine the degree of genetic diversity among the be...

The purpose of this paper was to estimate and to evaluate the hydration curves of three kinds of dry bean varieties (Phaseolus vulgaris L.), besides adjusting the Peleg’s model to the experimental values under several soaking temperatures. Bean seeds of pinto, black and red kidney varieties were soaked in distilled water in the temperatures of 20, 30, 40 and 50 °C. The constant C1 (Peleg rate c...

63 Bean rust is a devastating disease of common bean in the Americas and Africa. The historically 64 important Ur-3 gene confers resistance to many races of the highly variable bean rust pathogen 65 that overcome all known rust resistance genes. Existing molecular markers tagging Ur-3 for use 66 in marker assisted selection produce false results. We described here the fine mapping of Ur-3 67 fo...

• Research into the adoption of improved legume varieties provides evidence that farmers are now growing these in many developing countries and regions. • There has been large-scale adoption of improved chickpea varieties in southern India and small-scale adoption in the Horn of Africa. Specifically, there has been a shift in cultivated area from north to south/central India that is attributed ...

When crops are exposed to drought there is commonly an increase in solute-pool of the plant tissue. A series of experiments were conducted in 1994 and 1995 in the University of Hohenheim, Germany, to evaluate whether drought-induced solute accumulation per se will improve drought resistance, to determine the species of active osmotica involved, and to identify alternative mechanisms in grain le...

A high-performance liquid chromatography-diode array detection (DAD) procedure separating and quantifying 16 phenolic acids was used for determination of phenolic acids content in dry beans (Phaseolus vulgaris L.). Dry beans from 10 market classes and 15 varieties that are commonly consumed in the United States were screened for phenolic acids content. Systematic sequential hydrolysis of a mode...

A total of 992,682 single-nucleotide polymorphisms (SNPs) was identified as ideal for Illumina Infinium II BeadChip design after sequencing a diverse set of 17 common bean (Phaseolus vulgaris L) varieties with the aid of next-generation sequencing technology. From these, two BeadChips each with >5000 SNPs were designed. The BARCBean6K_1 BeadChip was selected for the purpose of optimizing polymo...

Introduction: Snap bean is a vegetable cultivated by small farmers in some mountainous and hillside regions of Colombian. Since the research of snap bean has not had the same importance as common beans in Colombia, little competitive varieties, compared to the quahty of the Blue Lake variety have been released, with a culti-variety with low tolerance to the biotic constraints of the tropic (Sil...
