متن کاملQuantitative Trait Loci Associated with Seedling Resistance to Isolates of Puccinia coronata in Oat.
ABSTRACT In our previous report, quantitative trait loci (QTL) for field adult plant resistance to crown rust were identified in an oat population of 152 F(5:6) recombinant inbred lines from the cross of 'Ogle' (susceptible)/MAM17-5 (resistant). The objectives of the present study were to identify in the same population, the number, genomic location, and effect of QTL and digenic QTL epistasis ...
متن کاملCrown Rust Development and Selection for Virulence in Puccinia coronata f. sp. avenae in an Oat Multiline Cultivar
Oat crown rust, caused by Puccinia coronata f. sp. avenae, is considered to be the most serious disease of oat (Avena sativa L.) in North America (27). It is distributed worldwide but is most damaging where heavy nightly dews occur in conjunction with moderate to high temperatures during the growing season. Under ideal conditions, crown rust can result in complete crop failure. In the United St...
متن کاملQuantitative trait loci in the Ogle/TAM O-301 oat mapping population controlling resistance to Puccinia coronata in the field.
Crown rust is the most damaging disease of cultivated oat (Avena sativa) and genetic resistance is the primary means of controlling the disease. Quantitative trait loci (QTL) with major and minor effects have been identified in Ogle1040 and TAM O-301 (most notably, Pc58 and PcNQMG/LGCG from TAM O-301 and OT-27 from Ogle1040) through single-isolate greenhouse and field tests. To map loci and det...
متن کاملGenome-wide association study for crown rust (Puccinia coronata f. sp. avenae) and powdery mildew (Blumeria graminis f. sp. avenae) resistance in an oat (Avena sativa) collection of commercial varieties and landraces
Diseases caused by crown rust (Puccinia coronata f. sp. avenae) and powdery mildew (Blumeria graminis f. sp. avenae) are among the most important constraints for the oat crop. Breeding for resistance is one of the most effective, economical, and environmentally friendly means to control these diseases. The purpose of this work was to identify elite alleles for rust and powdery mildew resistance...
