Molecular breeding for rust resistance in wheat genotypes.

摘要: Rusts are a group of major diseases that have an adverse effect on crop production. Those targeting wheat found in three principal forms: leaf, stripe, and stem rust. Leaf rust causes foliar disease wheat; Egypt, this significant annual yield loss. The deployment resistant genotypes has proved to be relatively economical environmentally sustainable method controlling the disease. Gene pyramiding can performed using traditional breeding techniques. Additionally, pathotypes introduced examine specific leaf genes, or breeder may conduct more complex methods. Indirect selection via DNA markers linked resistance genes facilitate transfer targeted either individually combination, even disease-free environment. use selective crosses counter virulent races resulted several into new germplasm from cultivated wild species. Quantitative trait locus (QTL) technology been adopted wide variety novel approaches is becoming increasingly recognized breeding. Moreover, researchers reported transference stripe susceptible cultivars.
