Identifying quantitative trait loci for resistance to Sclerotinia head rot in two USDA sunflower germplasms.
Sclerotinia head rot is a major disease of sunflower in the world, and quantitative trait loci (QTL) mapping could facilitate understanding of the genetic basis of head rot resistance and breeding in sunflower. One hundred twenty-three F2:3 and F2:4 families from a cross between HA 441 and RHA 439 were studied. The mapping population was evaluated for disease resistance in three field experimen...
متن کاملMain and epistatic QTL analyses for Sclerotinia Head Rot resistance in sunflower
Sclerotinia Head Rot (SHR), a disease caused by Sclerotinia sclerotiorum, is one of the most limiting factors in sunflower production. In this study, we identified genomic loci associated with resistance to SHR to support the development of assisted breeding strategies. We genotyped 114 Recombinant Inbred Lines (RILs) along with their parental lines (PAC2 -partially resistant-and RHA266 -suscep...
متن کاملSNP Discovery and QTL Mapping of Sclerotinia Basal Stalk Rot Resistance in Sunflower using Genotyping-by-Sequencing.
Basal stalk rot (BSR), caused by the ascomycete fungus (Lib.) de Bary, is a serious disease of sunflower ( L.) in the cool and humid production areas of the world. Quantitative trait loci (QTL) for BSR resistance were identified in a sunflower recombinant inbred line (RIL) population derived from the cross HA 441 × RHA 439. A genotyping-by-sequencing (GBS) approach was adapted to discover singl...

cabbage (brassica oleracea var. capitata) is an economically important and widely cultivated vegetable in urmia region, west azerbaijan, iran. during the surveys of cabbage diseases in the years 2009-2012, mature plants of both white cabbage (b. o. var. capitata f. alba) and red cabbage (b. o. var. capitata f. rubra) with yellowing and detaching of lower leaves, watersoaking, browning and softe...
متن کاملphylogeography and genetic diversity of the lesser mouse- eared bat (myotis blythii) in iran
in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
