“…Eps determines the time and duration of the reproductive phase. Of the three genes, only Eps gene acts independently of vernalization and photoperiod [19,20,62,63]. All the Vrn genes have been cloned [46,[64][65][66].…”

“…Hence, there is a lack of information on the genetics, physiological, biochemical functions and location of the Eps gene especially in barley [64,67,68]. Unfortunately, the access to the barley genome has not been straightforward because the genome consists of a large number of repetitive sequences [63,69]. Scientists have explored the opportunities in the colinearity of the genes among the cereals [63,67,70,71] for marker design and elucidation of the effects of the genes on yield and quality and their interaction with the environment in barley [63].…”

Barley heading date is important in adapting barley genotypes to different environments. Important factors affecting heading date in barley are temperatures, photoperiod and sowing date. Sowing date is a management option to influence heading date. It is used to reduce climatic risks such as frosts and water stress at sensitive periods during crop development. Three major genes control heading date in barley. These genes regulate photoperiod (Ppd-H1 and Ppd-H2), vernalization (Vrn-H1, Vrn-H2 and Vrn-H3) and the duration of the vegetative phase (Eps). The Ppd-H1 locus on chromosome 2(2H) regulates flowering time under long days. Ppd-H2 on 2H regulates phenology under short day length. Vernalization is mainly controlled by three loci (VRN-H1, VRN-H2 and VRN-H3), which interact in an epistatic fashion to determine vernalization sensitivity. Appropriate physiological and simulation frameworks such as that of APSIM-Barley are required to complement breeding efforts in order to determine the location of the Eps genes and describe and quantify the effects of environment and management on gene expression and their impact on yields and quality in barley.

Ensuring the health and safety of crops through the mitigation of harmful microorganisms is essential for maintaining agricultural productivity and food security. The yield of grain crops constitutes a critical metric for optimizing agricultural planning. The primary objective of this research is to investigate the efficacy of integrating common programming principles with the employment of mineral fertilizers and enhanced plant protection to augment the yield of grain crops under the prevailing natural conditions of the Zhetysu region in the Republic of Kazakhstan. The methodological framework of this study is grounded in the application of practical, applied research methods to assess the potential of yield programming for wheat and barley. This assessment is contingent upon the utilization of fertilizers and plant protection products within the specific agro-climatic context of southeastern Kazakhstan. It was observed that the treatment of seeds with protective-stimulating agents significantly improves the health and viability of cereal crops. These benefits are evidenced by the suppression of infections and enhancements in germination rates and pest resistance. Field experiments conducted within the Zhetysu region indicate that the sowing of pre-treated seeds in late April is conducive to optimal plant development and yield. The findings suggest that further research should concentrate on refining the application of fertilizers and protective agents to enhance predictive models and yield outcomes at a national scale.

Naked barley (Hordeum vulgare var. nudum) is a staple food crop, contributing significantly to global food security. Understanding genetic diversity will facilitate its effective conservation and utilization. To determine genetic diversity and its distribution within and among varieties, we characterized 30 naked barley varieties from Tibet, representing the traditional, modern, and germplasm-resources-bank gene pools, by analyzing SSR molecular fingerprints. The results demonstrate abundant genetic diversity in Tibetan naked barley varieties, particularly those in the traditional gene pool that holds much more private (unique) alleles. Principal coordinates and STRUCTURE analyses indicate substantial deviation of the modern varieties from the traditional and germplasm-resources-bank varieties. A considerable amount of seed mixture is detected in the modern varieties, suggesting the practices of using mixed seeds in modern-variety cultivation. Cluster analyses further indicate the narrow genetic background of the modern varieties, likely due to the limited number of traditional/germplasm-resources-bank varieties applied in breeding. Relationships between increases in genetic diversity and sample sizes within naked barley varieties highlight the importance of effective sampling strategies for field collections. The findings from this study have important implications for the sustainable utilization and effective conservation of different types of naked barley germplasm, both in Tibet and in other regions around the world.
