two spotted spider mite (tssm), tetranychus urticae koch, is an important pests on bean in markazi province (center of iran). to evaluate the bioacaricidal activity of extracts of three essential oils of thyme (thymus vulgaris), lavender (lavandula officinalis)  and eucalyptus (eucalyptus camaldulensis) against t. urticae on cherry bean (vigna unguiculta subsp. sinensis), five different concent...

ABSTRACT A previously unrecognized recessive resistance gene (or allele) was identified in three host group (HG) 3 common bean (Phaseolus vulgaris) cvs. Olathe, Victor, and UI 37, based on genetic analysis of plants from five populations screened with the NL-3 K strain of Bean common mosaic necrosis virus (BCMNV). The gene (or allele) was associated with resistance to leaf stunting and deformit...

Snap bean (Phaseolus vulgaris L.) is a major crop in the Great Lakes region of the United States. The most significant production occurs in Wisconsin, Michigan, New York, Illinois, and Pennsylvania. Snap bean crops also are produced in the Pacific Northwest, Georgia, Florida, and Ontario, Canada. In 2005, 124,367 ha of snap bean were harvested with a farm gate value of approximately $400 millio...

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...

Volatile compounds of uncooked dry bean {Phaseolus vulgaris L.) cultivars representing 3 market classes (black, dark red kidney and pinto) grown in 2005 were isolated with headspace solid phase microextraction (HS-SPME), and analyzed with gas chromatography mass spectrometry (GCMS). A total of 62 volatiles consisting of aromatic hydrocarbons, aldehydes, alkanes, alcohols and ketones represented...

Faba beans are widely consumed in Egypt as a vegetable by many ways. A study was conducted to determine the levels of phenolic compounds and antioxidant properties of raw seeds, green seeds and sprouts of ten faba bean cultivars commonly consumed in Egypt. Nubaria 2, Sakha 2 and Nubaria 1 cultivars showed higher amounts of phenolic compounds and exhibited the highest antioxidant activities (DPP...

the cotton bollworm, helicoverpa armigera (hübner), is one of the important polyphagous pests causing serious loss to many economically important crops in iran. the goal of this experiment was to study the age-stage, two-sex life table of h. armigera on different bean cultivars including white kidney bean (cultivars daneshkadeh, pak, and shokufa), red kidney bean (cultivars akhtar, naz, and say...

In most rainfed production areas in Iran, where wheat fallow is common, crop yield and resource sustainability could be improved by changing to more diverse crop rotation. It seems necessary to identify crop cultivars suitable for such diversification. This study was aimed to determine responses of two common bean (Phaseolus vulgaris L.) cultivars with different growth habits (Sayyad as an inde...
