evaluation of resistance to powdery mildew and some agronomic trails of barley doubled haploid lines
ninety barley doubled haploid lines originated from crossing between six barley cultivars in cereal research department, seed and plant improvement institute, karaj, iran were evaluated for resistance to powdery mildew and some agronomic traits in field in 2007. six parent cultivars and a powdery mildew susceptible check cultivar, afzal were also included. sixty two doubled haploid lines showed...
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 کاملInduction of Disease Symptoms in Barley by Powdery Mildew.
Powdery millews usually grow superficially on their hosts but produce symptoms of disease throughout the underlying host tissues. The symptoms include marked increase in respiratory rate (1, 3, 15. 24, 26, 30. 35); accumulation of organic and inorganic substances (1,29, 36): increase in dry weight (10. 26) ; increase in wet weight (3) decrease in photosynthesis when the disease is well develope...
متن کاملGenome dynamics and evolution of the Mla (powdery mildew) resistance locus in barley.
Genes that confer defense against pathogens often are clustered in the genome and evolve via diverse mechanisms. To evaluate the organization and content of a major defense gene complex in cereals, we determined the complete sequence of a 261-kb BAC contig from barley cv Morex that spans the Mla (powdery mildew) resistance locus. Among the 32 predicted genes on this contig, 15 are associated wi...
متن کاملHeterogeneity of Powdery Mildew Resistance Revealed in Accessions of the ICARDA Wild Barley Collection
The primary genepool of barley comprises two subspecies - wild barley (Hordeum vulgare subsp. spontaneum) and cultivated barley H. vulgare. subsp. vulgare. The former originated 5.5 million years ago in southwest Asia and is the immediate ancestor of cultivated barley, which arose around 10,000 years ago. In this study, the specific resistance of a set of 146 wild barley accessions, maintained ...
