영문 초록

Stripe rust (or yellow rust) caused by Puccinia striiformis f. sp. tritici is the major wheat disease responsible for deterioratingglobal wheat yield and quality. Although stripe rust appears to be prevalent mainly in temperate areas, new races adapting to high temperaturehave recently appeared in warmer areas, such as Australia, the Middle East, and Africa, increasing the threat to global food security. Amongthe approximately 80 reported genes for stripe rust resistance, six (Yr5, Yr7, Yr15, Yr18, Yr36, Yr46) have been cloned. Stripe rust resistancegenes are generally classified into race-specific (or all-stage) and non-race-specific (or high temperature adult plant) resistance genes. Whileresistance conferred by most race-specific genes are overcome by the appearance of new pathogen races within few years, non-race-specificgenes, such as Yr18, Yr36, and Yr46, provide more durable resistance and are often stable for several decades. Yr18/Lr34/Sr57/Pm38 andYr46/Lr67/Sr55/Pm46 are especially useful in breeding as they confer resistance to leaf rust, stem rust, and powdery mildew as well as striperust. Unlike the extensive global research efforts, few studies have been conducted in Korea regarding breeding and genetics for stripe rustresistance. To prevent damage by stripe rust in advance, it is important to monitor the changes in major pathogen races in Korea, evaluatemajor wheat breeding lines and landraces for stripe rust resistance by establishing an efficient screening system, and introduce new germplasmwith various resistance genes. Reinforcing wheat molecular genetics and genomics capacity is also important to enable identification of newstripe rust resistance genes and efficient transfer of the novel genes into elite wheat cultivars using molecular markers.
