Abstract: В статье изложены результаты исследований (2015-2017 гг.) раннеспелых селекционных линий сои северного экотипа в условиях Чувашской Республики. Такие свойства сои, как высота растений и прикрепление нижнего боба относятся к признакам технологичности и имеют влияние на урожайность. Независимо от того, что эти признаки присущи конкретному сорту, и они генетически определены, нами выявлено существенное влияние гидротермических величин на формирование высоты растений и прикрепление нижнего боба сои. Первый год исп… Show more

The data on morphobiological features and the main indicators of quality of the grain variety Civil are presented. The results of competitive testing are given, and the adaptability of the variety to different conditions of cultivation is shown. The need to develop early-ripening soybean varieties for agricultural production in the northern regions of Russia is noted, since the varieties with a growing season of 110-125 days do not ripen. Breeding work on soybean varieties was carried out at the experimental site under field conditions. The soil of the experimental field is gray forest heavy loam with a humus content of 4.1, close to neutral (with a soil solution reaction of 5.7), with a high content of mobile phosphorus and exchangeable potassium. The new variety Civil has a growing season of 83-105 days. The soybean variety of the northern ecotype Civil (breeding number 116 4/7-1sk) was bred by multiple individual selection in a hybrid population of F3-F8 obtained from the offspring of Chera-1 x SOUTH 30. The variety has been included in the State Register of Breeding Achievements of the Russian Federation since 2022 for the Central region (3). The new variety is characterized by early maturity, high yield, its potential yield exceeds 3.8 tons of grain/ha. The Civil variety differs from the zoned varieties by an increased oil content. The fat content in soybean seeds of this variety reaches 24%, which is 1.8% higher than that of the SibNIIK 315 standard variety. The inclusion of a new early maturing soybean variety of the northern ecotype Сivil in the soil and climatic conditions of the midland will contribute to the promotion of the crop in the northern regions of Russia.

Relevance. The soybean breeding process, focused on increasing the level of qualitative and reproductive indicators of the culture under the means of hybridization, further evaluation of the obtained genotypes and selection of promising samples, has an extremely relevant research direction.Results. The research determined how weather and climatic factors influenced the yield, protein content in seeds, and resistance to fungal diseases of promising soybean varieties under the conditions of Primorsky Krai. High-yielding accessions (3.08–3.59 t/ha) from combinations «Arisa × Taifun» and «NIISKH 3 × Taifun» were selected. A high TKW was characteristic of hybrid combination «Primorskaya 13 × Kofu» (207 g). During the growing season of the crop, there were conditions of insufficient (2021) and excessive (2022) moisture, which had a different effect on the yield level of soybean varieties on average according to experience (17.1 c/ha and 34.0 c/ha, respectively). The conditions of 2022 were optimal for the ontogeny of soybean. Varieties Primorskaya 1690, Primorskaya 1693, and Primorskaya 1696 had the highest yield in 2022 exceeding the standard by 38.0–54.7%. The highest yield was achieved under the conditions of short-term heavy precipitation in combination with high temperature during the growing period. Soybean seeds had a higher protein content after heavy precipitation with short periods of moisture excess from July to August. Under more favorable conditions for the development of fungal pathogens (in 2022), the degree of damage to soybean plants significantly increased (by 16.0%). The studied varieties were resistant to downy mildew and Cercospora.leaf spot (the degree of damage was up to 25.0%).
