A new gene Rph28 conferring resistance to barley leaf rust was discovered and fine-mapped on chromosome 5H from wild barley.
Abstract
Leaf rust is a highly destructive disease of barley caused by the fungal pathogen Puccinia hordei. Genetic resistance is considered to be the most effective, economical and eco-friendly approach to minimize losses caused by this disease. A study was undertaken to characterize and fine map a seedling resistance gene identified in a Hordeum vulgare ssp. spontaneum-derived barley line, HEB-04-101, that is broadly effective against a diverse set of Australian P. hordei pathotypes. Genetic analysis of an F3 population derived from a cross between HEB-04-101 and the H. vulgare cultivar Flagship (seedling susceptible) confirmed the presence of a single dominant gene for resistance in HEB-04-101 …
