efficacy of fomesafen and storm (bentazone+aciflorfen) herbicides on common bean (phaseolus vulgaris l.) weed control were evaluated in a randomized complete block design with four replications during 2008 in lorestan province. herbicides were applied postemergence at three trifoliate growth stage of common bean. herbicide injury on weeds reached maximum three days after treatments and common b...

Wild tepary beans (Phaseolus acutifolius) contain arcelins and arcelin-like (ARL2) proteins that are co-expressed with other proteins of the arcelin, -amylase inhibitors and phytohemagglutinins (APA) locus. Arcelin and ARL2 protein from a wild tepary bean accession G40199 were transferred into common bean cultivars ICA Pijao and Rojo. Inbred backcross lines were developed and selected for segr...

Several cover crops with potential for use in tropical and subtropical regions were assessed for susceptibility to three common species of root-knot nematode, Meloidogyne arenaria, M. incognita, and M. javanica. Crops were selected based on potential use as organic amendments in anaerobic soil disinfestation (ASD) applications. Nematode juvenile (J2) numbers in soil and roots, egg production, a...

Common bacterial blight (CBB), and bean common mosaic (BCMV) limit beans (Phaseolus vulgaris L.) production worldwide. This study was carried out to perform phenotypic screening asses the leaf reaction of a resistant line CBB BCMV. The experiment conducted using Completely Randomized design with three replications under screen-house conditions. Four improved genotypes for bruchid resistance wer...

The identification of germplasm genetic variability in breeding programs of the common bean (Phaseolus vulgaris) is essential for determining the potential of each combination of parent plants to obtain superior genotypes. The present study aimed to estimated the extent of genetic diversity in 172 lineages and cultivars of the common bean by integrating five tests of value for cultivation and u...

Common bean rust, caused by Uromycesappendiculatus, is one of the most devastating diseases in common bean. Breeding for resistant cultivars effective and eco-friendly method disease control. Although there no targeted breeding program Bulgaria to create pathogen, periodic screening virulent diversity U. appendiculatus sources resistance identified races/pathotypes carried out. During last twen...

Background: Effectiveness of Rhizobium inoculation is determined by common bean genotypes. Environmental factors also affect common bean genotypes-Rhizobium-symbiosis. The effect of common bean genotypes-Rhizobium strains-environment interaction on nodulation and common bean production is not well studied. Three genotypes (Dursitu, Gofta, and Kufanzik) and eight selected isolates of common bean...

Identity recognition systems allow plants to tailor competitive phenotypes in response to the genetic relatedness of neighbours. There is limited evidence for the existence of recognition systems in crop species and whether they operate at a level that would allow for identification of different degrees of relatedness. Here, we test the responses of commercial soya bean cultivars to neighbours ...
