- Abstract:
- ... Barley stripe rust, Puccinia striiformis f. sp. hordei, (PSH) occurs worldwide and is one of the major barley diseases of South Asia and North Africa. The aim of this study was to identify and map rust resistance loci at the seedling and the adult plant stages in 336 barley genotypes assembled at ICARDA as AM-2014. The seedling resistance to PSH was evaluated in the greenhouse individually for six ...

- Abstract:
- ... Heat stress at later growth stage is one of the major limitations in achieving potential yield in barley. Incorporation of heat tolerance in the variety development process is an essential task that breeders would like to achieve by exploring new sources of genetic variability and their utilization. A better understanding of genetic variation in existing genotypes under heat stress is required to ...

- Abstract:
- ... Spot blotch (SB) caused by Bipolaris sorokiniana and powdery mildew (PM) caused by Blumeria graminis f. sp. hordei are two important diseases of barley. To map genetic loci controlling susceptibility and resistance to these diseases, a mapping population consisting of 138 recombinant inbred lines (RILs) was developed from the cross between Bowman and ND5883. A genetic map was constructed for the p ...

- Abstract:
- ... Stem rust is an important disease of cultivated oat (Avena sativa) caused by Puccinia graminis f. sp. avenae. In North America, host resistance is the primary strategy to control this disease and is conferred by a relatively small number of resistance genes. Pg2 is a widely deployed stem rust resistance gene that originates from cultivated oat. Oat breeders wish to develop cultivars with multiple ...

The Sr13 functional gene CNL13 has haplotypes R1, R2 and R3. The R1/R3 and R2 haplotypes were originally designated as alleles Sr13a and Sr13b, respectively. To detect additional Sr13 alleles, we developed Kompetitive allele specific PCR (KASP™) mar ...

Races belonging to Ug99 (or TTKSK) continue to cause crop losses in East Africa and threaten global wheat production. Developing and deploying wheat varieties with multiple race-specific genes or complex adult plant resistance is necessary to achieve durability. In the present ...
