{"product_id":"2940148404088","title":"The Resistance of Bean Yellow Mosaic Virus (BYMV) in Faba bean (Vicia faba L.) with Diallel Analysis","description":"Bean yellow mosaic virus (BYMV) has been recognized as one of the major economic\u003cbr\u003edisease and reduced a considerable destructive in seed yield, particularly, when plants were\u003cbr\u003einfected at the beginning stage of faba bean growing regions of Egypt. Little genetic\u003cbr\u003einformation is available on the resistance of Vicia faba to BYMV disease. Hence, this study\u003cbr\u003ewas conducted to determine the relative importance of general (GCA) and specific (SCA)\u003cbr\u003ecombining ability, maternal and non-maternal reciprocal effects on resistance to BYMV in\u003cbr\u003eselected faba bean genotypes through mechanical transmation of BYMV. A complete diallel\u003cbr\u003emating scheme including reciprocals of six faba bean genotypes varied in their resistant and\u003cbr\u003esusceptible to BYMV were evaluated in the Experimental Farm, Faculty of Agriculture, Suez\u003cbr\u003eCanal University, Ismailia, Egypt during two seasons (2008\/09 \u0026amp; 2009\/010). The results\u003cbr\u003eshow that the combining ability analysis revealed that both additive and non additive gene\u003cbr\u003eeffects were present at this juncture and played a major role in the genetic resistance to\u003cbr\u003eBYMV. The crosses between the resistant and susceptible faba bean genotypes showed\u003cbr\u003eintermediate disease reaction to the BYMV, suggesting a polygenic system of resistance to\u003cbr\u003eBYMV. Significant maternal and specific reciprocal differences among the parents and their\u003cbr\u003ecrosses indicated that maternal inheritance is involved in the reaction of faba bean genotypes\u003cbr\u003eto BYMV. Also, significant genotype x years interaction suggested a deficient in stability in\u003cbr\u003ethe development of virus pathogen on faba bean plants. Therefore, recurrent selection would\u003cbr\u003ebe appropriate for accumulating genes for resistance to BYMV in V. faba and progeny performance may be based on their parent's performance per se.","brand":"ReadCycle","offers":[{"title":"Default Title","offer_id":47084154126576,"sku":"2940148404088","price":2.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940148404088_p0.jpg?v=1763702077","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940148404088","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
