The Russian wheat aphid (RWA; Diuraphis noxia [Kurdjumov]) is one of the world's most economically important and invasive pests of wheat, barley, and other cereals and has a crucial economic impact on autumnal wheat worldwide. The development of resistant cultivars may cause the continuous emergence of new RWA biotypes that are virulent for RWA control, emphasizing the need to determine new sources of resistance. Controlling RWA with systemic insecticides is economically expensive and hazardous to the environment and human health. Therefore, the most efficient way to control RWA is to ascertain and develop wheat cultivars with resistant genes. The presented study sought to determine the Dn genes in 25 wheat cultivars, including 19 cultivars from Uzbekistan's wheat breeding program and six cultivars from Russian breeding. The PCR screening proceeded with six (Xgwm44, Xgwm111, Xgwm635, Xgwm337, Xgwm642, and Xgwm473) SSR markers associated with Dn genes to recognize the genetic polymorphisms among the wheat cultivars. The results helped researchers in breeding programs, genetic improvement, and pest management, contributing to the economic viability of wheat farming. In turn, it enhances food security and promotes financial stability at both regional and national levels by increasing wheat yields and minimizing losses.

“…With advances in genetic mapping approaches, identifying DNA markers associated with economically important traits accelerates breeding processes significantly (Kushanov et al, 2021;Yoon et al, 2015). Developing distinct, efficient approaches helped identify genomic regions and genes that control and manage economically important traits in crop plants (Kushanov et al, 2017(Kushanov et al, , 2022. In particular, employing linkage mapping, linkage disequilibrium (LD)-based association mapping (AM), and nested association mapping (NAM) methods has benefited the mapping of quantitative trait loci (QTL) in different crop plants (Xu et al, 2017).…”

Wheat (Triticum spp.) is one of the premier staple foods consumed by one-third of the world’s population. Bread wheat (Triticum aestivum L.) is the only allohexaploid species with a genome formula BBAADD. Until now, from a selection point of view, a decline showed in the genetic potential of this type of wheat. However, the solution to this problem can be by developing high-yielding, disease- and pest-resistant cultivars using wheat-related species, ancient local landraces, and germplasm resources. Therefore, extensive study of the wheat gene pool using molecular tools, including identifying primary sources, is highly beneficial. For wheat improvement, breeding opportunities offer significant enhancements via genetic mapping approaches. The review focuses on the common wheat germplasm, wheat genetic approaches for genetic mapping, identification, and RWA (Russian wheat aphid) resistance, nested association mapping (NAM) population, DNA barcoding of Uzbekistan elite bread wheat cultivars, DNA marker-based screening of wheat germplasm for RWA resistance, future perspectives of wheat breeding in Uzbekistan, marker-assisted selection for abiotic stress tolerance, wheat stripe rust and its control strategies in Uzbekistan, epidemiology of the rust pathogens, pathogen characterization, and varietal resistance.

“…Gossypium species spread through large geographical and ecological areas and has a wide range of morphological and genetic diversity, mainly preserved in germplasm collections and as genetic materials for cotton breeding programs worldwide. These resources can be successfully used to transfer valuable traits from wild species into elite cultivars [ 6 , 7 ]. Polyploidization is one mechanism that introduces the genetic diversity of diploids to polyploids, which allows easy crossing with tetraploids and obtaining fertile hybrids.…”

Cotton (Gossypium spp.) is the most important natural fiber source in the world. The genetic potential of cotton can be successfully and efficiently exploited by identifying and solving the complex fundamental problems of systematics, evolution, and phylogeny, based on interspecific hybridization of cotton. This study describes the results of interspecific hybridization of G. herbaceum L. (A1-genome) and G. mustelinum Miers ex Watt (AD4-genome) species, obtaining fertile hybrids through synthetic polyploidization of otherwise sterile triploid forms with colchicine (C22H25NO6) treatment. The fertile F1C hybrids were produced from five different cross combinations: (1) G. herbaceum subsp. frutescens × G. mustelinum; (2) G. herbaceum subsp. pseudoarboreum × G. mustelinum; (3) G. herbaceum subsp. pseudoarboreum f. harga × G. mustelinum; (4) G. herbaceum subsp. africanum × G. mustelinum; (5) G. herbaceum subsp. euherbaceum (variety A-833) × G. mustelinum. Cytogenetic analysis discovered normal conjugation of bivalent chromosomes in addition to univalent, open, and closed ring-shaped quadrivalent chromosomes at the stage of metaphase I in the F1C and F2C hybrids. The setting of hybrid bolls obtained as a result of these crosses ranged from 13.8–92.2%, the fertility of seeds in hybrid bolls from 9.7–16.3%, and the pollen viability rates from 36.6–63.8%. Two transgressive plants with long fiber of 35.1–37.0 mm and one plant with extra-long fiber of 39.1–41.0 mm were identified in the F2C progeny of G. herbaceum subsp. frutescens × G. mustelinum cross. Phylogenetic analysis with 72 SSR markers that detect genomic changes showed that tetraploid hybrids derived from the G. herbaceum × G. mustelinum were closer to the species G. mustelinum. The G. herbaceum subsp. frutescens was closer to the cultivated form, and its subsp. africanum was closer to the wild form. New knowledge of the interspecific hybridization and synthetic polyploidization was developed for understanding the genetic mechanisms of the evolution of tetraploid cotton during speciation. The synthetic polyploids of cotton obtained in this study would provide beneficial genes for developing new cotton varieties of the G. hirsutum species, with high-quality cotton fiber and strong tolerance to biotic or abiotic stress. In particular, the introduction of these polyploids to conventional and molecular breeding can serve as a bridge of transferring valuable genes related to high-quality fiber and stress tolerance from different cotton species to the new cultivars.
