Genomics of Wheat, the Basis of Our Daily Bread

摘要: Wheat, being an important source of calories across the Americas, Europe, North Africa and Asia, is most widely grown food crop in world. Wheat yields have undergone a spectacular rise over last half century, contributing to Green Revolution Asia. However, productivity increases appear reached plateau recent years many consider that new advances genomics will be essential delivery rates necessary prevent hunger. New molecular tools enhance on-going wheat breeding, offering plant breeder considerable advantages time, cost, response selection. Perhaps importantly, it believed also facilitate much more efficient utilization sources genetic variation for agronomic traits from wild species. This chapter provides overview botany conventional breeding including summary past successes, current primary targets, major constraints achieving those goals. We then focus on genomic bread durum during decade implications these increasing resilience, stability tropical, sub-tropical semi-arid production systems includes use improve search for, characterization of, beneficial identification markers manipulation programs. Finally, we provide list currently available trait perspective likely future trends challenges breeding.
