New Disease Resistant Pea Now Available

U.S. Department of Agriculture (USDA) scientists in Pullman, Washington, grown Hampton, a new succulent dry pea accumulation that resists mixed pathogens of this legume crop. Two pathogens of sold regard are a pea enation mosaic pathogen (PEMV) and bean base hurl pathogen (BLRV). In serious cases, both of these aphid-borne pathogens can inflict stand waste of 80 to 90 percent, according to Rebecca McGee, a plant geneticist with USDA’s Agricultural Research Service (ARS).


Besides seed-yield losses, outbreaks of PEMV and BLRV also dispossess growers of an critical grain-rotation stand that can cut down on fake manure use—the outcome of a legume’s symbiotic attribute with nitrogen-fixing base bacteria, adds McGee, during a ARS’s Grain Legume Genetics and Physiology Research Unit, Pullman.

Fortunately, Hampton resists both of these viral threats as good as a accumulation of fungal pathogens that means Fusarium shrivel and powdery mildew. Hampton owes a extended illness resistance, high produce and other valued agronomic traits to a top-performing race of sixth-generation brood plants subsequent from channel dual ARS pea tact lines, PS810090 and PS510718.

McGee developed, evaluated and expelled Hampton as partial of a pea, lentil and chickpea germplasm-improvement module during Pullman together with collaborators from North Dakota State University, Washington State University,Montana State University and a University of Idaho.

During produce trials from 2008-2013 during 40 sites in Washington State, North Dakota, Idaho and Montana, Hampton constructed seed yields that exceeded those of a blurb cultivars Aragorn, Ariel and Banner by 12, 13 and 5 percent, respectively. Hampton is dictated for prolongation in a Pacific Northwest and Northern Plains, though is quite matched to a Palouse, a hilly, fruitful segment encompassing tools of southeastern Washington State, northeast Oregon and northwest Idaho.

The Washington State Crop Improvement Association is doing inquiries for approved seed of Hampton, that should be accessible to growers in open 2016.
