INTRODUCTION Including leguminous plants into crop rotation By 2050 demands of world population for protein helps to protect environment and nature, as well as increases two times. Plant protein sources may be to improve soil fertility and the diversity of an economically effective way to meet protein rhizosphere in consequence of biologically demand of population and improve the overall extraction of N2 [12]. quality of nutrition in future [2, 6]. Plant proteins serve to improve environmental sustainability, Lentil, in the condition of Uzbekistan, is included benefit human health, and in some cases reduces into the list of nontraditional agricultural crops and the risk of death [28]. is notable for its nutritional value, easy to digest, rich in protein and at present is mainly imported. Lentil (Lens culinaris Medik.) is a representative of Nowadays, the increase of demand for organic the Leguminosae family with low-calorie and high- products requires the creation and implementation protein quality [10]. Lentil is a dietary food source of new productive varieties of lentil. with its content, depending on its different varieties, up to 30% protein [26] and rich in Grain productivity is the main complex microelements such as iron (Fe), selenium (Se), characteristic which appears in the result of manganese (Mn), copper (Cu) as well [12,27,]. interrelation of plant characteristics and changes Protein content of this grain has high concentration under the influence of environment [30]. of essential amino acid such as lysine, leucine, In studying agricultural crops, breeders are rarely isoleucine, valine and phenylalanine. Including, interested in studying a single trait of a plant, in according to the content of the grain (rich in addition, it is important to study the correlation methionine, tryptophan, etc.), in addition to between different traits, especially the correlation meeting the protein requirements of the world’s between yield and other traits. Selection is an vegetarian population [1, 18], is considered as a integral part of breeding, and with the help of “meat for poor men” [22]. selection, genotypes with high productivity can be Agrotechnical importance of lentil is high, due to obtained. Determining the correlation between symbiotic peculiarities with legume bacteria as agronomic characteristics, their correlation with other leguminous plants, it is considered as a yield productivity and their direct effect on grain nitrogen fixer plant, assimilates free nitrogen from yield allows selection of varieties with high air and contributes its role in nitrogen cycle [28]. productivity [30]. https://www.theamericanjournals.com/index.php/tajabe 23 THE USA JOURNALS THE AMERICAN JOURNAL OF AGRICULTURE AND BIOMEDICAL ENGINEERING (ISSN – 2689-1018) VOLUME 06 ISSUE10 Improvement of breeding processes plays an conditions of our Republic, was not studied important role in increasing crop productivity. enough. It is important to analyze the correlation Statistical analysis of the correlation among the between crop capacity and physiological characters that ensure productivity is widely used characteristics of lentil. Based on this, the purpose in breeding processes. of the research is to study the correlation between the productivity of lentil and the physiological In selection and genetic research, various research characteristics of the plant. methods are used in complex assessment of initial materials. Direct assessment of the selected MATERIALS AND METHODS character is difficult in some cases, and in this case The experiments were conducted in 2022-2023 in correlation analysis is used [26]. Correlation is a “Durman” field experimental base of the Institute relationship that describes the degree of of Genetics and Plant Experimental Biology of the relationship between two variables. It shows how Academy of Sciences of the Republic of Uzbekistan. strongly a pair of variables is correlated [5]. In order to study and use the collection samples of With the help of the correlation coefficient, it is gene pool of promising and high-value leguminous possible to evaluate the relationships between plants, as well as valuable economic characters and different characters at the genotypic and resistance to adverse climatic conditions of lentil, phenotypic level, the connection of a certain like other leguminous plants, correlation analyses character with environmental factors, the laws of of valuable economic and physiological passing of the character from the parental forms to characteristics were conducted on nineteen the next generations [16]. genotypes. These samples were selected from the The laws of variation of traits and the correlation of experimental nursery-gardens “Lentil quantitative indicators allow to determine the International Elite Nursery Global 2021” (LIEN- value of each trait to use in selection processes [3].
