The introduction of desirable agronomic characteristics into Phaseolus vulgaris L. is being attempted by interspecific hybridization with P. coccineus, but the effects on root nodulation are unknown. Accordingly, cross-inoculation relationships between P. vulgaris `Red Kidney' and P. coccineus ’Scarlet Runner' were tested in the greenhouse with a group of 16 Rhizobium strains effective on Red K...

The coconut bug, Pseudotheraptus wayi Brown (Heteroptera: Coreidae), is a major pest of a wide range of economically important crops in Eastern and Southern Africa. The suitability of French beans, Phaseolus vulgaris L. (Fabales: Fabaceae) as an alternative food for mass rearing of P. wayi was determined by elucidating its development, survival, and reproduction on French bean pods in the labor...

The genus Phaseolus (Fabaceae) consists of some 50 species, all of which are distributed in the Americas. Four of these contain cultigens. P. vulgaris (common bean), P. lunatus (lima bean), P. acutifolius (tepary bean), P. coccineus subsp. coccineus (runner bean); and P. coccineus subsp, polyanthus (no English vernacular name). Biochemical markers--phaseolin seed storage protein and isozymes--h...

The effect of four species of legume seeds on plasma cholesterol levels and faecal steroid excretion was studied in pigs. Thirty-six growing boars were randomly allocated in groups of six to six diets which they ate continuously for 42 d. The diets fed were: 1, a semi-purified (SP; control group 1) diet; 2, SP + 10 g cholesterol/kg (control group 2); 3, 4, 5, 6, SP + cooked legumes (70:30, w/w;...

Legume seeds stored under high temperature and humidity develop a texture defect known as hard-tocook (HTC). Structural and histochemical characteristics of normal and HTC beans (Phaseolus vulgaris) were studied after storing them at 5°C/40% relative humidity (RH) or 40°C/75% RH for 60 days. Cotyledonary cells of HTC beans showed contraction of the cell content, whereas the cytoplasm of normal ...

Background: Beans constitute one of the most important grain legume species from socioeconomic point view, playing an essential role in a sustainable agriculture and food safety nutrition. In fact, beans contain rich diversity nutrients, highlighting their high protein, starch fiber content. Canary Islands have considerable beans, including three five cultivated Phaseolus: P. coccineus, lunatus...
