Introduction Grass pea consumption leads to neurolathyrism and a safer use of this environmentally adaptable crop needs cultivars with decreased neurotoxin levels. Were they cross-compatible, grass peas would be useful genetic resources for disease resistance breeding of peas (Pisum sativum L.). In vitro selection (9) and gene transfer may provide grass peas better adapted for consumption, whil...

twenty accessions of cultivated grass pea (lathyrus sativus l.) and wild species of lathyrus l.collected from western and southern regions of iran were evaluated for their mitotic metaphase chromosomalcharacteristics. all populations comprising 16 populations of cultivated l. sativus and 4 wild populations oflathyrus l. were diploid, 2n=2x=14 chromosomes. there were significant variations among...

Improved sources of home-grown protein are required to substitute for animal proteins and soyabean meal in ruminant feeds. The present dominance of grassland feeds for protein supply in Britain is highlighted and possibilities for increasing microbial protein (MP) supply on grass-based diets are considered. There are particular opportunities for improving MP supply and animal performance from t...

Three studies were conducted to evaluate the feasibility of field peas as a protein source in diets for beef cattle. In the first study, 4 cultivars of field pea were incubated in situ to determine rate and extent of CP disappearance. Results indicate that field pea cultivars vary in CP content (22.6, 26.1, 22.6, and 19.4%, DM basis for Profi, Arvika, Carneval, and Trapper, respectively). Solub...

The effects of irradiation (0, 1.8, and 4.5 kGy) on the quality of frozen corn and peas were investigated during a 12month period of postirradiation storage at -18 degrees C. Irradiation of frozen corn and peas caused a reduction in ascorbic acid content of both vegetables and a loss of texture in peas but had no significant effects on instrumental color parameters (L*, a*, and b*), carotenoid ...

Primiparous (n = 9) and multiparous (n = 18) Holstein cows averaging 584 +/- 15 kg of body weight (mean +/- SE) were allotted at 2 wk postpartum to nine groups (3 primiparous and 6 multiparous) of 3 cows each to determine the effects of pea extrusion on ruminal degradability and milk production. Cows were fed a total mixed diet based on timothy silage and concentrate for ad libitum intake. The ...

The aim of the present study was to cross-culturally adapt and validate the Spanish version of the Performance Enhancement Attitude Scale (PEAS). A cross-sectional multi-sample survey with 17 independent datasets was carried out. Cross-cultural adaptation of the PEAS into Spanish was conducted through forward/backward translations, consensus panels and comparative analyses of known-groups to es...

Crop traits can alter economically important interactions between plants, pests, and biological control agents. For example, a reduced waxy bloom on the surface of pea plants alters interactions between pea aphids and their natural enemies. In this study, we assess whether the effect of wax reduction extends beyond the 2 or 3 arthropod species closely associated with the plants and into the str...

The effects of dehulling and micronization (infrared heating) on the nutritive value of three cultivars (Impala, Radley, and Sirius) of peas (Pisum sativum) varying in coat color for broiler chickens were studied. Dehulling increased (P < or = 0.05) protein and starch contents and decreased (P < or = 0.05) fiber content of peas. Also, the concentrations of most amino acids slightly increased (P...
