Abstract/ Executive Summary:

Rust is the most devastating fungal disease in wheat. Three rust diseases, namely, leaf or brown rust caused by Puccinia triticina Eriks, stem or black rust caused by Puccinia graminis f. sp. tritici West, and stripe or yellow rust caused by Puccinia striiformis f. Tritici Eriks, is the most economically significant and common diseases among global wheat cultivars. Growing cultivars resistant to rust is the most sustainable, cost-effective, and environmentally friendly approach for controlling rust diseases. To date, more than 187 rust resistance genes (80 leaf rust, 58 stem rust, and 49 stripe rust) have been derived from diverse wheat or durum wheat cultivars and the related wild species using different molecular methods. This review provides a detailed discussion of the different aspects of rust resistance genes, their primitive sources, their distribution in global wheat cultivars, and the importance of durable resistant varieties for controlling rust diseases. This information will serve as a foundation for plant breeders and geneticists to develop durable rust-resistant wheat varieties through marker-assisted breeding or gene pyramiding.

Program Area: Variety and Species

Commodity: Wheat

Objectives:

The aim of the present review is to describe the most recently developed approaches for introducing rust resistance genes into bread and durum wheat cultivars
and their related species. To accomplish this, we collected current information on rust disease-resistance genes (leaf, stem and stripe), including their primitive
sources and their chromosomal positions, and discuss their potential applications for developing durable resistant wheat varieties through MAS.

Methodology:

This review paper is written based on the secondary information.

Achievement/Findings:

Knowledge regarding the characteristics and distribution of rust resistance genes is essential for developing new wheat varieties with resistance. Gene pyramiding
through MAS and the use of different molecular approaches is essential for ensuring the sustainability of long-term resistance in wheat cultivars and for controlling
these widespread and dangerous wheat diseases. Consolidating information on durable resistance varieties and their mechanisms for controlling rust disease,
which is the focus of this paper, is also important for the development of new disease-resistant varieties with high-yielding capabilities. Overall, this work aims to support
wheat researchers, students, academics, plant breeders and pathologists by enhancing understanding of the current state of the field of wheat research.
