Diversification and Population Structure in Common Beans (Phaseolus vulgaris L.)
Wild accessions of crops and landraces are valuable genetic resources for plant breeding and for conserving alleles and gene combinations in planta. The primary genepool of cultivated common beans includes wild accessions of Phaseolus vulgaris. These are of the same species as the domesticates and therefore are easily crossable with cultivated accessions. Molecular marker assessment of wild bea...
متن کاملGeometry applied to breeding common beans (Phaseolus vulgaris).
The primary components of common bean (Phaseolus vulgaris) grain yield (W) are the number of pods (X), the number of grains per pod (Y), and the weight of the grains (Z). In 1964, Grafius suggested using geometry in plant breeding; W corresponds to the volume of a parallelepiped with three axes, X, Y, and Z. Because the cube is the largest parallelepiped by volume, maximum yield is obtained whe...
متن کاملMolecular and morphological taxonomy of Pythium species isolated from soil in West Azarbaijan province (N.W. Iran)
Pythium is a fungus-like genus with worldwide distribution that is found in most terrestrial and aquatic ecosystems. It is a species-rich genus contains important plant pathogenic species. Little is known on the systematics of Pythium in West Azarbaijan province (N.W. Iran). Thus, the aim of this study was to identify 200 isolates collected from different cultivated soils of West Azarbaijan pro...
متن کاملNutritive Value of Navy Beans (phaseolus Vulgaris).
It has been known since 1920 (Johns & Finks, 1920) that the navy bean is an inferior source of protein for rats. Everson & Heckert (1944) reported that raw navy beans were injurious to rats when given at a 10% protein level. They also reported that autoclaving the beans destroyed the injurious effect. Kakade & Evans (1963a, b) confirmed this report and observed that rats given 10% protein as ra...
متن کاملPOTENTIAL ANTIOXIDANT AND CHELATING ACTIVITY OF PROTEIN FRACTIONS FROM COMMON BEANS (Phaseolus vulgaris)
In this work, we evaluated antioxidant and metal chelating activities of common bean proteins. Protein fractions were produced by using extraction with organic (method 1) or aqueous (method 2) solvents. Results evidenced that the amount of proteins extracted through method 2 was higher than method 1, probably due the chemical difference between solvents. The antioxidant activity of hard-to-cook...
