“…Genotypes with similar morpho-physiological responses to drought stresses were grouped together within the same cluster. Cluster 2 contained the highest number of sugarcane genotypes (13), followed by cluster 3 (11), 1 (8), and 4 (8). In general, cluster 1 was characterized by F v /F m , RWC, LR, and LD.…”

“…Employing molecular markers for the selection of drought-tolerant sugarcane genotypes is a promising approach to enhance breeding efficiency and precision. Various molecular markers, such as random amplified polymorphic DNA (RAPD; [ 10 ]), inter simple sequence repeat (ISSR; [ 11 ]), and amplified fragment length polymorphism (AFLP; [ 12 ]), have been used in identifying and selecting drought-tolerant sugarcane genotypes. However, the complex genetics of sugarcane, characterized by its polyploid and aneuploid genome, present significant challenges for molecular breeding efforts.…”

Drought is a significant constraint to sugarcane productivity. Therefore, understanding how different varieties of sugarcane respond to drought stress can facilitate breeding programs and set up criteria for selecting drought-tolerant varieties. In the present study, we examined eight morpho-physiological traits to distinguish 40 sugarcane genotypes categorized into four groups based on significant differences in cane yield under non-stressed conditions and reduction of cane yield under drought-stressed conditions. The study was conducted during the formative stage in a greenhouse, encompassing both control and drought conditions. Drought treatments resulted in significant changes and differences in the mean values of various morpho-physiological traits. The hierarchical clustering analysis, utilizing stay-green traits such as higher chlorophyll fluorescence ratio (Fv/Fm), leaf chlorophyll content (SPAD), leaf relative water content (RWC), and lower leaf rolling score (LR), leaf drying score (LD), and drought recovery score (DR), successfully grouped 40 sugarcane genotypes into four major clusters, similar to the previously categorized groups. Correlation analysis showed significant relationships among cane yield, reduction of cane yield under drought conditions, and the stay-green traits. Our results demonstrated that morpho-physiological traits contributing to the “stay-green” phenotypes could be useful as selection criteria for drought tolerance in sugarcane.

“…Molecular selection in eight sugarcane genotypes (BOT-41, Co-775, Co-997, F-153, F-161, GT54-9, G84-47, and Sp80-32-80) regarding drought tolerance was also performed using RAPD, ISSR, and R-ISSR (combined RAPD and ISSR) markers. Among these, the use of R-ISSR was proved to be more efficient than the independent selection with RAPD or ISSR [54]. A further selection of these genotypes was carried out with AFLP primers by amplifying 886 amplicons with 6.2% polymorphism; this analysis established Co-997 as the most tolerant and Co-775 as the most susceptible to drought of the eight tested genotypes [55].…”

Sugarcane (Saccharum spp.) is one of the most important industrial cash crops, contributing to the world sugar industry and biofuel production. It has been cultivated and improved from prehistoric times through natural selection and conventional breeding and, more recently, using the modern tools of genetic engineering and biotechnology. However, the heterogenicity, complex poly-aneuploid genome and susceptibility of sugarcane to different biotic and abiotic stresses represent impediments that require us to pay greater attention to the improvement of the sugarcane crop. Compared to traditional breeding, recent advances in breeding technologies (molecular marker-assisted breeding, sugarcane transformation, genome-editing and multiple omics technologies) can potentially improve sugarcane, especially against environmental stressors. This article will focus on efficient modern breeding technologies, which provide crucial clues for the engineering of sugarcane cultivars resistant to environmental stresses.

“…According to the research consistent increase in the yield of cultivated varieties is based on the improvement of their cultivation technologies and the achievements of breeding [4]. Using of molecular methods in the breeding process is particularly relevant at the present, which is confirmed by a long list of scientific publications on the study of genetic variability of oats [5][6], triticale [7][8][9][10][11][12] and wheat [12][13][14].…”

During the research, 15 genotypes of grain crop (4 spiecies of Hordeum and 11 of Triticum) from the genbank collection of the Scientific Center of Agrobiotechnology were studied. The gluten locus of all studied cultivated and wild species is polymorphic consisting of GluA, GluB, GluC, GluD, GluE alleles. Moreover, GluB, GluC and GluD alleles have the highest meeting frequency, it is 82.35%. The GluE allele has the lowest frequency of occurrence at 41.17%. The following genotypes were formed in the gluten locus: GluAA, AB, BB, BC, CC, CD, DE, EE, EF, the frequency of which is equal to 47.05, 29.53, 70.58, 82.35, 76.47, 17.65, 52.94, 35.29, 23.53 and 23.53%. The highest frequency was recorded for GluBC genotype (82.35%), and the lowest for GluAB, EE, EF (25.53%) genotypes. In the studied species of wild barley, homozygosity is 60-100%, in the case of wild wheat - 66.7-71.42%. Indicators are close to the genetic makeup of free-breeding populations. It ranges from 50-80% in wheat amphidiploids and 25-60% in non-amphidiploids. The genetic similarity index of wild barley species ranges from 0.488 to 0.648, which indicates a unique and rich biodiversity. Meanwhile, it is quite high (r=0.844) in wild types of wheat. For amphidiploid x wild einkorn wheat, it is 0.982-0.982. In other cases, the genetic similarity index ranges from 0.488 to 0.648.
