Acceptance of experiments

On August 5, 2022, in accordance with the schedule for the acceptance of experiments in the scientific divisions of the Institute of Vegetable and Melon Growing of the NААS, the next acceptance of scientific experiments of the solanaceae family under PND 20 "Vegetable and Melon Growing" was held with the tasks:

17.01.01.30.P. Formation and maintenance of genetic diversity of vegetable and melon crops to ensure selection programs. Stage 2022: Evaluate introduced samples, select valuable ones for inclusion in the genebank to determine benchmark varieties of valuable economic traits. (Project Manager: Inna MITENKO, Ph.D. (Agr.). 208 samples of the gene pool of 8 types of vegetable and melon plants were planted in open and closed soil conditions (tomato - 76 samples, sweet pepper - 31, eggplant - 11, carrot - 19, table beet - 13, large-fruited, nutmeg and hard-skinned pumpkin - 2, watermelon – 10, garlic – 46). In the current year, 33 samples from Ukraine, Russia, Germany, the Netherlands, Italy, and the USA were introduced.

20.00.01.01.F Development of a methodology for creating stress-tolerant lines and varieties of nightshade plant species based on induced mutagenesis and recombinogenesis during intraspecific and interspecific hybridization. Stage 2022: Study of the relationship between the recombination parameters of meiosis and the degree of heterosis and dominance by quantitative and qualitative traits in hybrids F1 tomato. Creation of hybrid combinations of F1 tomato on a sterile basis and a tomato line with B gene expression based on mutational and synthetic selection. (Project Manager: Serhiy KONDRATENKO, Dr. Sci (Agr.), Senior Research Fellow). According to research objectives, 125 samples of tomato and 10 samples of eggplant of different genetic origin are studied in 6 nurseries: 1) development of elements of the theoretical and practical basis of mutation selection of tomato; 2) development of elements of theoretical and practical basis of recombination selection of tomato; 3) identification of plants with male gene sterility for obtaining F1 tomato hybrids; 4) evaluations of F1 tomato hybrids obtained on a sterile basis; 5) methodological developments regarding the problems of tomato mutation selection; 6) backcrossing and gametophyte selection among eggplant interspecific hybrids.

20.00.01.03.F Development of methods for determining and predicting complex quantitative traits in genotypes of vegetable crops of the family Solanaceae L. Stage 2022: Determination of relationships between traits in tomato, pepper, and eggplant samples and features of the genetic organization of complex quantitative traits (Project Manager: Roman KRUTKO, PhD (Agr.), responsible performers^ Junior Research Fellow Lyubov PYLYPENKO, graduate student Andriy MARUSYAK). Tomato samples were identified based on the presence of mutant genes in the genotype, manifested on the vegetative parts of the tomato plant. The regularities of the intensity of anthocyanin coloration of pepper and eggplant plants at the early stages of plant growth and on mature plants were analyzed White Lilia and Iceberg eggplant samples with the absence of anthocyanin coloring of the vegetative parts of the plant were selected. When carrying out phenological observations of tomato, sweet pepper and eggplant plants, samples with extra early flowering were selected: 5 tomato samples, 7 sweet pepper samples and 1 eggplant sample.

The conclusion of the commission is to accept the research, the level of research performance is excellent.
