“…To ensure genetic resistance, identification of new or effective resistance genes in different germplasms of global wheat cultivars or wheat relative species is essential [6]. Identification of Lr genes by multipathotype testing or gene postulation is labour-intensive and timeconsuming.…”

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.

“…This has not only accelerated the identification of desired genes for specific traits in a breeding program but has also facilitated the development of new varieties by reducing the time required for precise introgression of desired genes. Moreover, identification of molecular markers for resistant genes has efficiently facilitated their pyramiding into valuable backgrounds in less time (Tanksley et al 1989;Sumikova and Hanzalova 2010).…”

Leaf rust is one of the most destructive diseases of wheat causing huge economic losses throughout the world. Several leaf rust resistance genes have been identified and genetically mapped, some of which have also been cloned including the adult plant resistance gene Lr34. Selection of wheat genotypes carrying Lr34 can be accomplished with the help of expression of a morphological marker leaf tip necrosis (LTN) which is linked with Lr34. However, recording of LTN under field conditions is time and labor intensive thereby slowing down the process of selection of desirable genotypes. Use of molecular markers which are tightly linked to Lr34 can be more efficient in precise identification of lines carrying this gene in a short span of time. We selected a total of seven such markers that were earlier reported to be linked with Lr34. The objective of the study was to assess the suitability of these markers in distinguishing Indian bread wheat genotypes carrying Lr34 from those which lacked Lr34. The haplotype analysis suggested that one STS marker (csLV34) and two gene specific markers (cssfr2 and cssfr5) could distinguish wheat genotypes carrying Lr34 from those lacking it. Use of these markers in breeding program can accelerate the speed of selection of desirable genotypes.
