Evaluation of Traits and Genetic Diversity of Sugar Beet O-Type Lines for Rhizomania Tolerance using SSR Molecular Marker
Extended Abstract Introduction and Objective: Sugar beet is one of the most important agricultural products in the world and most of the sugar consumed in our country is prepared from this plant. Plant breeding programs are based on creating variety and selection of quantitative and qualitative traits. Examining genetic diversity is the first step in breeding programs. Material and Methods: I...
متن کاملconfirmation of repulsion molecular markers linked to rhizomania resistance gene (rz1) and evaluation of gene dose effect in sugar beet genotypes
rhizomania is the most important disease of sugar beet in iran and some other parts of the world, and plays an essential role in decreasing sugar yield in fields. the best approach to control this disease is to use resistant varieties. tagging the resistance genes in breeding programs, by molecular markers is necessary. in this study, some breeding populations and commercial varieties of sugar ...
متن کاملMolecular breeding for resistance to rhizomania in sugar beets
Lennefors, B-L. 2006. Molecular breeding for resistance to rhizomania in sugar beets. Doctor’s dissertation ISSN: 1652-6880, ISBN: 91-576-7255-5 Rhizomania is one of the most destructive sugar beet diseases. It is caused by Beet necrotic yellow vein virus (BNYVV) vectored by the soilborne protoctist Polymyxa betae Keskin. The studies in this thesis evaluated natural and transgenic resistances t...
متن کاملThe hrpZ Gene of Pseudomonas syringae pv. phaseolicola Enhances Resistance to Rhizomania Disease in Transgenic Nicotiana benthamiana and Sugar Beet
To explore possible sources of transgenic resistance to the rhizomania-causing Beet necrotic yellow vein virus (BNYVV), Nicotiana benthamiana plants were constructed to express the harpin of Pseudomonas syringae pv. phaseolicola (HrpZ(Psph)). The HrpZ protein was expressed as an N-terminal fusion to the PR1 signal peptide (SP/HrpZ) to direct harpin accumulation to the plant apoplast. Transgene ...
متن کاملdevelopment of an snp marker for sugar beet resistance/susceptible genotyping to root-knot nematode
linked and/or gene-based molecular markers have been used widely in marker-assisted selection (mas) to differentiate resistant and susceptible genotypes. resistance to meloidogyne spp. in beta vulgaris l. is mediated by a single dominant gene (r6m-1). using allele-specific primers (asps), an snp marker harboring a single nucleotide polymorphism (a/g), linked to the resistance gene was developed...
متن کاملارتباط بین یک نشان‌گر مولکولی ناجفت با شدت آلودگی به ریزومانیا در مزرعه و غلظت ویروس در ریشه چغندرقند
The aim of the present study was to determine the relationship between a repulsion molecular marker with resistance to rhizomania in infested field condition and virus concentration in sugar beet root (ELISA absorbance values). For this purpose, the genotypes were planted in infested area of Shiraz in the randomized block design with four replications. At the end of the season, the roots were h...
