The objects for the study were 9 zoned varieties approved for cultivation in the Middle Volga region and 5 winter common wheat varieties developed by the FSBRI CBFC. The zoned winter common wheat variety ‘Fotiniya’ was used as a standard. The years of the varieties’ study were divided into favorable, typical (mean) and unfavorable (dry, excessively wet). Winter common wheat productivity in favorable years averaged 5.68 t/ha, in typical years it was 4.32 t/ha and 2.19 t/ in unfavorable years. As a result of determining the response of winter common wheat varieties in changing agroclimatic conditions according to productivity, there was proven a strong effect of environmental conditions and genotype. There have been proposed for breeding use such valuable and stable genotypes of winter common wheat as ‘Biryuza’, ‘Skipetr’, ‘Don-eko’, ‘Alyonushka’, ‘Pamyati Krivobocheka’, ‘Surskaya Nika’, ‘Dargo’, which should be placed on a high and medium agricultural background. The varieties ‘Fotiniya’ and ‘Klavdiya 2’ are highly adaptable to unfavorable cultivation conditions and will have an advantage over other varieties in medium and low agricultural backgrounds.","PeriodicalId":330770,"journal":{"name":"Grain Economy of Russia","volume":"22 18","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140980371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The soil of the experimental plot was ordinary blackearth, with a humus layer thickness of 140 cm. The climate is characterized by aridity with unstable moisture. The years of the study were contrasting in temperature and moisture availability (HTC 0.49–0.83). Due to the uneven distribution of precipitation during a vegetation period of maize, the temperature regime through the months and moisture availability had even greater differences (HTC 0.11–2.28). The objects of research were 96 maize hybrids. The main method for developing hybrids was an interline hybridization.

To analyze and study this issue 26 varieties of the collection nursery were studied on the fields of the laboratory of breeding and primary seed production of ISA, a branch of the FSBI FRAEC VIM, located in the forest-steppe agroclimatic zone of the Ryazan region in 2021–2023. To calculate the adaptability parameters, there were used the following coefficients and indicators: adaptability coefficient (AC), yield range (d, %), homeostatic index (Homi), variety yield stability level index (VISLi, %), environmental adaptability (a linear regression coefficient) (bi), stability of the trait (σd2), index of environmental conditions (Ij), stability factor (SF), genetic flexibility of the variety (Ymin+Ymax/2), stress resistance (Ymin–Ymax) and coefficient of responsiveness to favorable growing conditions (Cr), calculated using appropriate methods. The study has established that the dominant influence (66.4 %) on the variability of the trait ‘1000-grain weight’ of the studied varieties is made by the factor “year” (growth and development conditions). A significant contribution to the formation of the indicator “weight of 1000 grains” is made by the meteorological conditions of the grain filling phase (July) – HTC (r = +0.722 p = 0.01) and the amount of precipitation (r = +0.637, p = 0.01). 80.8 % of the 26 varieties studied belonged to the large-grain group (1000-grain weight was more than 50.0 g), the average varietal yield of the varieties was quite high with 6.84 t/ha. Based on the principle of ranking the obtained indicators of adaptability of the trait ‘1000-grain weight’ and its components, there were identified the varieties ‘Dobry’, ‘Magutny’ (Republic of Belarus) and ‘Lenetah’ (USA), which took, respectively, first, second and third places in the rating scale.

Three-factor analysis of variance has shown that external conditions have a major effect on productivity formation of wheat varieties. The main influence on overall productivity was made by various forecrops (factor ‘forecrop’ had 46.3 %). The share of variability due to differences in the conditions of the plants’ vegetation period in different years (the factor ‘year’) was 15.1 %. The interaction of the factors ‘year × forecrop’ made a significant contribution to the overall productivity variability with 20.2 %. Favorable conditions for the formation of wheat varieties’ productivity were determined when sown in green manure fallow with the indices of environmental conditions (Ij = +12.8). The least favorable conditions were with maize for grain (Ij = 0.1) and the worst with sunflower (Ij = -12 ,9). On average, over the years of the study (2021–2023), the productivity of winter common wheat varieties ranged from 74.7 hwt/ha for the variety ‘Ayuta’ to 84.4 hwt/ha for the variety ‘Premiera’.

Identification and implementation of the most effective methods of field crops, growing using crop rotation and fertilizers remains an urgent task.   The purpose of the current research was to study the effect of crop rotations and doses of mineral fertilizers on productivity of winter wheat grain, to analyze the economic and energy efficiency of its cultivation in the conditions of the Central Blackearth region.   The study was carried out in the conditions of the experimental field of the Federal Agricultural Kursk Research Center in 2016, 2020. The soil of the experimental plot was typical medium-loamy, medium-humus blackearth (chernozem). The experimental scheme included such factors as grain-fallow-row crop, grain-grass-row crop, and grain-grass rotations; with doses of fertilizers or without fertilizers, N20P40K40 and N40P80K80. The weather conditions for the rotations of the studied crop rotations differed slightly. As a result of the study, there was found that winter wheat grain productivity in grain-grass and grain-grass-row crop rotations was 17.2 and 13.8 % lower than in grain-fallow-row crop rotation. When applying mineral fertilizers at a dose of N40P80K80, the largest winter wheat productivity was 4.52 t/ha. The lowest cost of grain was established in the grain-fallow-row crop rotation, which varied from 4.68 to 5.04 thousand rubles/t due to higher yields compared to other studied crop rotations and with a dose of N20P40K40 (4.68, 4.80 and 4.97 thousand rubles/t, respectively for crop rotations).
