“…Among these genes, at least 27 genes, including Sr2 (Yr30), Sr13, Sr21, Sr22, Sr24, Sr25, Sr26, Sr27, Sr28, Sr32, Sr33, Sr35, Sr36, Sr37, Sr39, Sr40, Sr42, Sr44, Sr45, Sr46, Sr47, Sr51, Sr52, Sr53, Sr55 (Lr67/Yr46/ Pm46), Sr57 (Lr34/Yr18/Pm38), and Sr58 (Lr46/Yr29/Pm39), are effective or partially effective against the Ug99 race group [91][92][93][94][95][96][97][98][99][100]. Among these 27 genes, Sr2, Sr13, Sr22, Sr25, Sr26, Sr35, Sr39 and Sr40 were reported to be the most effective against Ug99 [87,[101][102][103]. A brief description of the details of these genes is given in Table 4.…”

“…The Sr2 is present in approximately 60% of current CIM-MYT spring wheat germplasms [101], including some high-yielding wheat varieties that also have high levels of resistance to leaf rust and stripe rust, as well as desirable end-use quality characteristics. Similarly, more than 50% of International Centre for Agriculture Research in the Dry Areas (ICARDA) and South African wheat germplasms have shown an SSR haplotype association with the durable stem rust resistance gene Sr2 [195].…”

“…The stem rust resistance genes Sr25 and Sr26 are effective against variants of Ug99, TTKST and TTTSK [87,95], The stem rust resistance gene Sr31 is very common in world wheat varieties. Before the emergence of Ug99, stem rust resistance was maintained mainly by Sr31 in most countries around the world, except for Australia [101].…”

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, are 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.

“…A new variant of this stem rust race has been found in Kenya since 2006, which is virulent on Sr24 [28,29]. Now a day fungicides are being used to control stem rust in Kenya [30]. It ultimately jumped the red sea and its presence has been reported in Yemen since 2006 and was also found in Sudan in the same year.…”

Wheat along with rice and maize is fulfilling half of the calories demands of the world. Global Wheat production has increased tremendously since green revolution in 1960's and helped in minimizing hunger and malnutrition. Developing countries, which consume 60% of the global wheat production, have shown a higher yield increase than the developed countries in the past [1]. It was driven by the hunger prevalence in these countries and was attributable to the introduction of high yielding and rusted resistant semi dwarf varieties developed under the collaborative efforts of International and National research systems during the last 50 years. Whereas, climate change and the emergence of new pests and diseases are threatening the food sustainability. The evolution of new races of disease pathogens like stem rust (Ug 99) is of serious concern. In order to feed the ever increasing population we have to increase wheat production at the rate 1.6% which can be achieved by developing high yielding varieties having a good tolerance level for biotic and abiotic stresses.
