The blue aleurone colour was dominated for the most studied accessions. The ANOVA between subspecies associated with canonical variate analysis and hierarchical clustering confirms the finding to be used in barley breeding through incorporation of the candidate gene into the commercial varieties.

Molecular mechanisms for covered vs. naked caryopsis in barley. — Okayama University
Update: This workshop is postponed. Call for Papers link. September , 12th Australasian Plant Breeding Conference. Can plant breeders of the 11th millennium, with all their technological skills, guarantee feeding the world's population while coping with increasing environmental stresses? Comparison of three genomic regions identified in our study with locations of C.

In , Afanasenko et al. In , Haas et al. Recently, Wang et al. Three SNP loci corresponding to this region had suggestive p -values in case of Kr2 tests Table 1 , so the resistance locus on chromosome 2H may also contribute to resistance to Kr2-isolate Fig. The resistance QTL found on chromosome 2H in our study is likely coincident with previously identified QTLs for seedling resistance [ 2 , 7 ]. Later, Afanasenko et al. Besides this chromosome region another part of chromosome 2H distal part of the long arm is associated with resistance to spot blotch.
Wang et al. Position of genetically mapped marker from this set is Bovill et al. Later, Zhou and Steffenson [ 9 ] revealed seedling and adult resistance loci on chromosome 3H in positions 9. More proximal loci on chromosome 3H also have been found. Bilgic et al.
Grewal et al. Information on SNPs related with seedling resistance to Kr2 and Ch3 isolates as well as results of variety resistance assessment can be useful for further marker-assisted selection of spring barley. A total of 96 accessions from the Siberian spring barley core collection were selected for phenotyping.
Half of these accessions were cultivars and lines developed in breeding centers located in Siberia from Altay, Buryatiya, Irkutsk, Kemerovo, Novosibirsk, Omsk, Tomsk, Tyumen and Yakutiya regions. Two plants of each barley genotype and cultivar Harrington as a susceptible control were evaluated for resistance in each tray in a completely randomized design with three replicates. Two C. Isolate Ch3 has been used in previous studies for evaluation of resistance of a wide set of barley genotypes and showed high aggressiveness on susceptible barley genotypes.
Isolate Kr2 was chosen because of its origin and good sporulation ability. This scale is based on the lesion size and the degree of associated chlorosis. Low IRs 1. Types of reactions were recorded only if susceptible cultivar Harrington demonstrated high IRs.
