Current Trends in Wheat Breeding Strategies for Developing Domestic Wheat Cultivars in Korea

Wheat, in conjunction with rice and maize, constitutes one of the three most significant staple crops worldwide, sustaining over 40% of the global population. In Korea, the annual per capita wheat consumption exceeds 30 kg, totaling approximately 4 million tons nationwide. However, more than 95% of this demand is met through imports, resulting in a meager self-sufficiency rate of approximately 0.7%, raising concerns regarding supply stability and price fluctuations. Enhancing wheat self-sufficiency in Korea requires addressing yield reductions caused by abiotic stressors, including elevated temperatures, drought, cold damage and pre-harvest sprouting induced by climate change, as well as biotic stressors such as Fusarium head blight. The development of high-quality wheat varieties with superior processing characteristics that satisfy consumer demands is crucial. This study provides critical insights for future research on the development of novel wheat cultivars in Korea. It reviews the current state of wheat cultivation and production, environmental and biological factors affecting growth, compositional elements influencing quality, domestic cultivars developed through conventional crossbreeding currently in commercial distribution, and contemporary breeding trends, with particular emphasis on novel breeding technologies, such as biotechnology.
