Association mapping for resistance to powdery mildew in oriental tobacco (Nicotiana tabaccum L.) germplasm
Powdery mildew caused by Erysiphe cichoracearum is an important fungal disease which threatens tobacco (Nicotiana tabacum L.) production. The objective of this study was to determine DNA markers linked to genomic regions associated with resistance to powdery mildew in tobacco through the association mapping approach. Seventy tobacco geno-types were fingerprinted using 26 simple se-quence repeat...
متن کاملgenetic analysis of powdery mildew resistance in some barely lines
powdery mildew, caused by blumeria graminis hordei, is currently the most serious foliar disease of barley in worldwide and reduced barley yield. the use of resistant cultivars is an efficient, economical and environmentally way to control of powdery mildew in barley. in this research a half diallel design was used for genetic analysis of resistance to powdery mildew (bgh) in barley. six barley...
متن کاملinvestigation of genetic diversity and broad sense heritability in watermelon accessions of sistan
to conserve the genetic resources and identify the strong and weak points in sistan watermelon accessions and compare these with improved cultivars of: sugarbaby and fairfax, an experiment was carried out, based on rectangular lattic design of two replications in 2007. the morphological traits studied, included plant length, plant weight, seed weight, fruit number, fruit length, fruit width, su...
متن کاملTempered mlo broad-spectrum resistance to barley powdery mildew in an Ethiopian landrace
Recessive mutations in the Mlo gene confer broad spectrum resistance in barley (Hordeum vulgare) to powdery mildew (Blumeria graminis f. sp. hordei), a widespread and damaging disease. However, all alleles discovered to date also display deleterious pleiotropic effects, including the naturally occurring mlo-11 mutant which is widely deployed in Europe. Recessive resistance was discovered in Eth...
متن کاملApplication of Glycerol for Induced Powdery Mildew Resistance in Triticum aestivum L.
Previous work has demonstrated that glycerol-3-phosphate (G3P) and oleic acid (18:1) are two important signal molecules associated with plant resistance to fungi. In this article, we provide evidence that a 3% glycerol spray application 1-2 days before powdery mildew infection and subsequent applications once every 4 days was sufficient to stimulate the plant defense responses without causing a...
