Özet
<p>The term "ploidy" refers to changes in the chromosome number or set of a plant. Plants are classified differently based on their ploidy levels. Polyploidy is defined as the presence of more than two sets of chromosomes in plant somatic cells and is considered one of the breeding methods applicable to all plants. The polyploidy technique is widely used in plants for various purposes, including increasing leaf, flower, fruit, and seed sizes, enhancing plant resilience to abiotic and biotic stress factors, intensifying colors, increasing the content of various chemical compounds, and promoting the emergence of new combinations by increasing genetic diversity. Various studies have shown that polyploidy affects the morphological, chemical, physiological, and ecological characteristics of plants. Polyploidy can occur naturally in plants, with examples such as wheat (<em>Triticum aestivum</em>), cotton (<em>Gossypium hirsutum</em>), tobacco (<em>Nicotiana tabacum</em> L.), and potatoes (<em>Solanum tuberosum</em>). Additionally, researchers can artificially induce polyploidy to improve various traits in plants. Different chemicals such as colchicine, oryzalin, trifluralin, chloral hydrate, ether, chloroform, and phenylurethane, as well as heat shocks, are used to promote polyploidy. This review summarizes some polyploidy breeding studies in the field of field crops and aims to be helpful to researchers aspiring to work in this area.</p><p><strong>Keywords:</strong> Ploidy, polyploidy, chromosome, colchicine, plant breeding, field crops</p><p><br></p>
