“…Photoperiod genes have a great impact on wheat heading and fl owering, and are also important physiological traits of wheat, which aff ect the ecological adaptability of wheat together with vernalization [3,6]. Studies have shown that wheat photoperiod response is mainly controlled by three major genes, Ppd-A1, Ppd-B1 and Ppd-D1, which are homologous genes, and are located on chromosomes 2A, 2B and 2D, respectively; among them, Ppd-D1 locus has the strongest eff ect, followed by Ppd-B1 locus, and Ppd-A1 locus is the weakest [7,[24][25][26]. When the gene loci are dominant (Ppd-A1a, Ppd-B1a and Ppd-D1a), wheat is insensitive to photoperiod, while recessive allelic variants (Ppd-A1b, Ppd-B1b and Ppd-D1b) are sensitive [27][28][29].…”

“…When the gene loci are dominant (Ppd-A1a, Ppd-B1a and Ppd-D1a), wheat is insensitive to photoperiod, while recessive allelic variants (Ppd-A1b, Ppd-B1b and Ppd-D1b) are sensitive [27][28][29]. The three alleles have diff erent responses to photoperiod, among which Ppd-D1a gene has the strongest insensitivity to photoperiod, followed by Ppd-B1a, and Ppd-A1a is the weakest [25,27]. At present, four major vernalization genes (VRN-A1, VRN-B1, VRN-D1 and VRN-B3) and photoperiod gene Ppd-D1 locus in wheat have been cloned, and corresponding functional markers have been developed, which can be used to detect and analyze the related functional genes of wheat materials by molecular markers.…”

The vernalization characteristics of wheat are mainly controlled by vernalization and photoperiod genes, which determine the winter-spring habit and heading-flowering of wheat, and affect its environmental adaptability. In order to understand the effects of vernalization and photoperiod genes on heading date, 12 common wheat varieties widely cultivated in the Huang-Huai region were used as experimental materials, and the effects of different low-temperature vernalization treatments on wheat heading date were studied. Using molecular markers from previous studies, the allelic variations and genotypes of vernalization genes (VRN-A1, VRN-B1, VRN-D1 and VRN-B3) and photoperiod genes (Ppd-A1, Ppd-B1, Ppd-D1) were detected. By identifying the heading date in a controlled greenhouse, the relationship between the vernalization and photoperiod genes composition and the heading date phenotype was analyzed. The experimental results showed that different wheat varieties had different phenotypes after different vernalization treatments. Tian min 198 carried a dominant vernalization gene, and its vernalization characteristics were expressed as spring wheat varieties, with low requirements for low-temperature vernalization. Wheat without a dominant vernalization gene had winter wheat characteristics, with high requirements for low-temperature vernalization. Wheat varieties carrying a dominant vernalization gene can be used to improve late-maturing wheat varieties, and serve as valuable germ plasma resources for variety improvement and introduction. Exploring the effects of different wheat vernalization and photoperiod genes composition on heading date is beneficial to provide a scientific basis for the rational use of wheat varieties, and studying the vernalization and photoperiod genes composition has guiding significance for wheat introduction and ecological breeding.

“…Modern genetics and breeding of crops, including cotton, has several theoretically and practically acute relevant fundamental and applied developments, methodological approaches, methods, and techniques that are successfully applied by qualified breeders and seed growers, [12], [10], [23], [24]. Thus, [20] believe that one of the methods for unlocking the genetic potential of cotton varieties is the method of selecting parent pairs for crossing according to the principle of the origin of genotypes, intra-varietal, inter-varietal, and complex hybridization, which will make it possible to create new varieties of medium fiber cotton purposefully, most adapted to the soil and climatic conditions of the Turkestan region.…”

The Turkestan region is a cotton-growing zone in the south of Kazakhstan, which is the northernmost cotton-growing zone in the world. 115-125 thousand hectares of medium-staple cotton (Gossypium hirsutum L.) are cultivated here annually, of which 80-85 thousand hectares are sown in the Maktaaral and Zhetysay districts. This region is highly susceptible to salinity, drought, invasion of dangerous pests (cotton budworm, beet borer, spider mites, aphids), and diseases (fusarium blight (wilt), gummosis). Considering the high salt content in the arable soil horizon, the aridity of the climate of the Turkestan region are the main limiting factor of the region, and selection and genetic methods is the most effective and economical way to reduce their negative impacts on cultivated vegetation, then research work on the study and creation of new resistant cotton varieties in these soil and climatic conditions are relevant. Considering all the above problems, scientists of the Agricultural Experimental Station of Cotton and Melon Growing LLP have set themselves the goal of creating heat- and drought-resistant, precocious cotton varieties with high productivity, resistance to salinization, diseases, pests, possessing high technological qualities as the yield and quality of fiber of types III-IV, based on previously obtained ones during hybridization of intraspecific and interspecific lines of families. For 30 years, scientist-breeders of Kazakhstan have created 13 varieties of medium-fiber cotton, of which 8 are approved for use in the Turkestan region in the Republic of Kazakhstan. The research method is based on hybridization, multiple selection, and testing of offspring by the half method, according to the full diallel scheme (first Griffing model for F1). The created seven varieties PA-3031, PA-3044, M-4005, M-4007, M-4011, Bereke-07, Myrzashol-80, and M-4017 are zoned for more than 92% of the acreage in cotton-growing farms in the south of Kazakhstan, for the variety M-5027, which is resistant to pests, the patent has been issued 2021 and in 2022 it is planned to enter it into the register of approved varieties.

“…Recent work in developing physical maps of common wheat (Triticum aestivum L.) include gene mapping of target traits (Goncharov and Watanabe 2005;Distelfeld et al 2006) and mass EST-SSRs mapping of the wheat chromosome (Mohan et al 2007). Integration of physical and genetic maps for target gene(s) on specific chromosome regions (Sourdille et al 2002;Liu et al 2004;Mohler et al 2004;Diéguez et al 2006;Dilbirligi et al 2006) has also been conducted to improve overall mapping accuracy.…”

Physical maps of chromosomes provide a framework for organizing and integrating diverse genetic information. DNA microarrays are a valuable technique for physical mapping and can also be used to facilitate the discovery of single feature polymorphisms (SFPs). Wheat chromosome arm 2BL was physically mapped using a Wheat Genome Array onto near-isogenic lines (NILs) with the aid of wheat-rice synteny and mapped wheat EST information. Using high variance probe set (HVP) analysis, 314 HVPs constituting genes present on 2BL were identified. The 314 HVPs were grouped into 3 categories: HVPs that match only rice chromosome 4 (298 HVPs), those that match only wheat ESTs mapped on 2BL (1), and those that match both rice chromosome 4 and wheat ESTs mapped on 2BL (15). All HVPs were converted into gene sets, which represented either unique rice gene models or mapped wheat ESTs that matched identified HVPs. Comparative physical maps were constructed for 16 wheat gene sets and 271 rice gene sets. Of the 271 rice gene sets, 257 were mapped to the 18-35 Mb regions on rice chromosome 4. Based on HVP analysis and sequence similarity between the gene models in the rice chromosomes and mapped wheat ESTs, the outermost rice gene model that limits the translocation breakpoint to orthologous regions was identified.
