“…В засушливых условиях Средневолжского региона для селекции на короткостебельность наиболее ценен исходный материал, который помимо генетически обусловленной низкой высоты растений имеет ряд других положительных признаков, например, устойчивость к полеганию благодаря более толстой и прочной соломине, высокая урожайность зерна и др.

The work was carried out in 2018-2019 in the forest-steppe zone of Samara region. The purpose of the research is to conduct study samples of collection nursery of various ecological and geographical origins and identify new sources of economically valuable traits for breeding in the forest – steppe of the Middle Volga region. The material for research was 352 collection samples of spring soft wheat, including 108 foreign varieties and hybrids and 244 domestic samples of breeding institutions of the Russian Federation. Meteorological conditions during the research years were quite severe, and vegetation took place in arid and acutely arid conditions (hydrothermal coefficient in 2018 – 0.51, in 2019 – 0.48, with a long-term value in the region of 0.73). The greatest variability over the years of research was observed in the indicators of grain yield of samples (Сv=23.9...27.5 %) and plants height (Сv=10.8...12.9 %). According to the research results, 30 new genetic sources of economically valuable traits of spring soft wheat were identified. Sources of precocity (period of shoots-earing 35...37 days): Uralskaya kukushka, Chelyaba rannyaya, Tyumenskaya 25, Lutescens 70, Odeta, Libertina, Chi Mai, Long Fu 7, M83-1551. Sources of short stems (plants height 40...45 cm): KWS Torridon, KWS Jetstream, Florens, Eleganza, Long Fu 13. Sources of consistently high productivity (grain yield 415...554 g/m2, and the yield increase over the standard 71...210 g/m2): Erythrospermum 4089, Grekum 5523, Lutescens 6029, Lutescens 6074/6-23, Lutescens 6102/1-32, Lutescens 6102/1-34 Erythrospermum 6517/24-1, Ekada 214, Burlak, Ulyanovskaya 105, Lebedushka, Saratovskaya 73. Sources of high protein content (15.4...16.7 %) and gluten (36.0...42.0 %) in grain: Erythrospermum 3898, Erythrospermum 4112, Erythrospermum 4171, Erythrospermum 5289

In the process of breeding work with the Pisum satvum L. it was noticed that the same samples in different years may belong to different gradations of plant classification according to stem length. Resistance to lodging (RL) of samples in years with contrasting heat and moisture conditions may also have different estimates. In this connection, the purpose of the research was to identify the dependence of plant height and resistance to lodging of peas on the hydrothermal coefficient (HTC) of the growing season. The research was carried out in 2019 2023 in the forest-steppe of the Krasnoyarsk Territory, in the competitive variety testing nursery of the pea breeding laboratory of the Krasnoyarsk Research Institute of Agriculture. The soil of the site is represented by ordinary chernozem of medium thickness, medium humus with neutral acidity. For the study, 8 samples of selfselected peas were taken. Samples were arranged in a systematic manner in quadruplicate, the plot area being 15 m2. During the research, it was revealed that in order to objectively characterize pea samples by stem length and its resistance to lodging, it is necessary to take into account the HTC of the growing season, since the differences between the lengths of plants in years of different HTC of the growing season can change by 2 times. The length of plants depended significantly on the hydrothermal coefficient of the growing season; separately for the months of the growing season, it was revealed that the strongest direct correlation is typical for August r ± Sr = 0.88 ± 0.08. The maximum lodging of samples was noted during an excessively humid growing season, the minimum during a dry one, the difference in the assessment could reach one point. An increase in HTC had the maximum effect on reducing the resistance to lodging of semi-dwarf samples and the entire sample; medium-sized samples showed an average degree of dependence. When analyzed by month of the growing season, the greatest influence on the decrease in plant resistance to lodging had the August HTC r ± Sr = -0.95 ± 0.18, p = -0.75.
