“…Height of the triticale plants is positively correlated with the biomass and negatively correlated with the yield index [9,10]. Various studies have obtained variable results on the effect of the height of the plants on certain structural elements of the yield, including spike length, grain number per spike, spikelet number per spike, 1000-grain weight, and grain yield; these parameters are apparently determined by specific genotypes and experimental conditions [7,11,12,13].…”

Triticale is a relatively new crop which still possesses serious drawbacks that can be significantly improved by breeding. The dwarfing genes proved to be very useful in the development of new lodging resistant and productive cultivars of winter triticale. The aim of our research was to assess the effect of the Ddw1 dwarfing gene from rye on the agronomic valuable traits in spring triticale. The Ddw1 effect was studied in the greenhouse experiment in segregating the F2:3 population and in the field of F3:4 and F4:5 families derived from crossing winter triticale ‘Hongor’ (Ddw1Ddw1) and spring triticale ‘Dublet’ (ddw1ddw1). As a result, in all three generations, a strong decrease in plant height was demonstrated that was accompanied by a decrease in grain weight per spike and 1000-grain weight. In field experiments, a decrease in spike length and increase in spike density and delay in flowering and heading were observed. As a result of decrease in culm vegetative weight due to Ddw1, the harvest index measured in F4:5 increased. The spike fertility and number of grains were not affected by Ddw1. The comparison of Ddw1 in rye, winter, and spring triticale, and the possible role of Ddw1 in improving spring triticale are discussed.

Triticale is an artificially created crop. When creating new varieties of this crop, different types of wheat, rye, and wild cereals are used in modern breeding. In connection with the origin uniqueness of triticale, its genetic characteristics, questions of a methodological nature often arise in breeding work. One of these questions is the method choice of selection and evaluation of parent plants, the establishment of breeding nurseries. In this regard, the aim of the research was to improve the selection method of winter triticale parental plants and the establishment of a breeding nursery of the 1st year. Field and laboratory studies were carried out in 2019-2021 in the Izhevsk State Agricultural Academy. A comparative characteristic of the initial inflorescences’ selection methods and establishment of a breeding nursery of the first year was given. Inflorescences’ selection was carried out based on visual inspection without threshing and based on a morphological assessment of the ear and grain after thrashing. The breeding nursery of the 1st year was founded in two ways - by sowing seeds and unthreaded ears. The effectiveness of the breeding nursery establishment method was assessed by comparing the yield of breeding lines and the number of culled forms. It was found that at the initial stage of winter triticale breeding process, it is advisable to select the initial forms based on the weight of the ear, establish the 1st year breeding nursery with an unthreaded ear and carry out a comprehensive assessment and culling of breeding material based on field and laboratory methods. This will significantly increase the volume of breeding material and improve the quality of assessments, reduce labor intensity in the culling of selected inflorescences and lines.

Relevance. Currently, there is a tendency to increase the volume of lettuce cultivation in hydroponics. Such specific conditions for growing lettuce hydroponically as high humidity in the root zone, different levels of illumination throughout the year and specific mineral nutrition, dictate a number of necessary characteristics that varieties should possess. In addition, the lettuce variety for hydroponics should consistently give high yield and have good consumer qualities. Accordingly, it is necessary to carry out selection separately for specific hydroponic conditions. And for theoretical justification of the selection of lettuce varieties for this technology and increasing the efficiency of the breeding process, it is necessary to form a model of the variety, which was the goal of this research.Methods. The 13 most common lettuce varieties were research: 8 light green and 5 dark green Batavia. The morphological characteristics of plants in the phase of industrial ripeness were described and the biometric traits of plants were determined.Results. Based on research in 2021-2023 the 13 most commonly hydroponically grown lettuce varieties of the Batavia variety have been defined as the variety model criteria for hydroponics. The characteristics of a leaf rosette, leaf blade, indicators of early ripening and productivity inherent in these varieties were identified, and a model of the variety was formed on their basis.
