Changing climatic conditions and the loss of immunity to diseases and pests of the developed varieties make breeding work to create new genotypes of great necessity. The new middle-early maize hybrid ‘Zernogradsky 299 MB’ of universal direction of economic use (for grain and green fodder) has been developed in the “Agricultural Research Center “Donskoy”. The hybrid is three-linear; it belongs to the varieties with crown yellow grain Zea mays L. indentata. It possesses high values of the main economically valuable traits. The average grain productivity through 3 years of competitive variety testing (2014–2016) was 5.36 t/ha, the variety yield exceeded the standard variety ‘Zernogradsky 291 AMB’ on 0.41 t/ha (8.3%). The average productivity of green mass is 27.6 t / ha, which is higher than that of the standard variety on 2.4 t/ha (9.5%). The new hybrid is resistant to lodging (2.1% of lodged plants), drought-resistant, resistant to smut on a natural background (0.4% of affected plants), has a high starch percentage (71.9%). In 2018, according to the results of the State Variety Testing, a new hybrid was introduced into the State List and approved for use in the Central Blackearth and NizheVolzhsky regions to cultivate it for grain and green fodder. It has a high potential for grain productivity. The maximum yield (11.23 t/ha) was obtained in the Central Blackearth region on the Oboyansk plot of the Kursk region, which is higher than the standard variety ‘Voronezhsky 279 CB’ on 2.03 t/ha (22.1%) with lower grain harvesting moisture (on 1,6%) than the standard variety.

The studies were carried out in 2016–2018 in the competitive variety testing of peas on the crop rotation fields belonging to the laboratory of legume breeding and seed-growing of the FSBSI “Agricultural Research Center “Donskoy”, located in the part of the Rostov region with unstable humidity (Zernograd). During the years of research, the meteorological conditions of the pea vegetation were contrast that made it possible to objectively estimate the pea lines in the given weather and climate conditions. In the com­petitive variety testing, the 18 lines were studied according to economically valuable traits (seed productivity, productivity elements, adaptability to machine harvesting). As a result of the study, the 6 pea lines were identified: 2 lines of the mustache morphotype “G-1002”, “G-1003”; 4 leafy lines “G-1010”, “G-1011”, “G-1013” and “G-1015”. In the group of the mustache morphotype, 2 lines “G-1002” (on 0.30 t/ha), “G-1003” (on 0.39 t/ha) exceeded the grain productivity of the standard variety for 3 years of study on aver­age. The productivity increase was from 12.4 to 16.1%. In the group of variety samples of the leafy morphotype, the line “G-1010” (on 0.31 t/ha) significantly exceeded grain productivity of the standard variety. All the selected lines were tolerant to their seed-shedding. The line “G-1010” (48.8 pc per plant) showed the highest seed yield per plant. The lines “G-1003” (222.1 g), “G-1011” (209.5 g) and “G-1013” (207.8 g) had the largest fineness of grain. The line “G-1010” (8.85 g/plant) demonstrated the highest productivity per plant. However, having a low coefficient of resistance to lodging (0.35), this line has the greatest loss of seeds during harvesting. The iden­tified lines will be used in further breeding work according to a number of their economically valuable traits.

The purpose of the current study was to consider and identify promising peas lines with high grain productivity and determine their adaptability parameters. The field study was carried out at the FSBSI “Agricultural Research Center “Donskoy”, located in the southern part of the Rostov region during the 4-year competitive variety testing (2017–2020). The objects of the study were 19 breeding lines developed by the FSBSI “Agricultural Research Center “Donskoy”. All lines were of a leafless type. The standard variety was the variety ‘Aksaysky usaty 5’. The lines ‘G-1002’ (2.60 t/ha), ‘G-1003’ (2.81 t/ha), ‘G-1005’ (2.58 t/ha), ‘G-1007’ (2.56 t/ha), ‘G-1014’ (2.63 t / ha) and ‘B-3790/30-3’ (2.54 t/ha) showed a significant excess over the standard variety. The mean productivity in the competitive variety testing of 2017–2020 was 2.41 t/ha. The maximum productivity difference among the years was 1.63 t/ha, or 89% of the mean productivity. This indicates a high contrast of the cultivation conditions over the years. There have been identified the adaptability parameters of the pea lines (stress resistance, genetic flexibility, homeostaticity and breeding value), which exceeded grain productivity of the standard variety. The lines ‘G-1014’ (5.31), ‘G-1007’ (6.12), and ‘B-3790/30-3’ (6.47) showed the highest homeostaticity. The productivity of these lines was more even over the years and it is preferable to cultivate them in contrasting conditions (zones of risky farming, low agricultural background). The lines ‘G-1002’ (4.19), ‘G-1005’ (4.53) were a bit inferior to them. The line ‘G-1003’ had the lowest level of homeostaticity (3.98). The lines ‘G-1014’ (1.49), ‘G-1007’ (1.47), ‘B-3790/30-3’ (1.44) were characterized with the greatest indicator of breeding value. According to the results of the competitive variety testing in 2017–2019, in 2019 the line ‘G-1003’ with the highest grain productivity, was sent to the State Variety Testing under the name ‘Zernogradsky usaty’ in the North Caucasian (6) region. According to the estimation results of the adaptive properties, the variety is responsive to the improvement of cultivation conditions and has been recommended for cultivation in intensive technology.

Productivity Potential

Alfalfa and sainfoin have always been the main perennial fodder legumes in the south of Russia. Because of their economic and biological properties, crop and fodder production have always relied on their cultivation and will rely on it in the future. Insufficient cultivated areas of these legumes make it impossible to provide livestock with balanced feed, to use climatic, soil and plant resources rationally. The study of the varietal composition of alfalfa and sainfoin developed in the FSBSI “Agricultural Research Center “Donskoy” showed that the productivity potential of these varieties makes it possible to obtain a fairly high yields of forage under various weather-climatic conditions. For 6 years the average yield of green mass of the standard variety “Rostovskaya 90” was 27.0 t/ha in the first cutting and 18.1 t/ha in the second cutting, and in the total for two cuttings it is 45.1 t/ha. In the first cutting for 5 years out of 6, the green mass pro­ductivity of the alfalfa varieties “Lyutsiya” and “Selyanka” significantly exceeded the standard variety. On average for two cuttings, green mass productivity of the varieties “Lyutsiya” (47.8 t/ha) and “Selyanka” (48.9 t/ha) was higher than that of the standard variety. The yield of absolutely dry matter of the standard variety “Rostovskaya 90” varied from 6.7 t/ha to 7.7 t/ha in the first cutting and from 4.3 t/ha to 5.2 t/ha in the second cutting. The yield of absolutely dry matter of the alfalfa varieties “Lyutsiya” and “Selyanka” reliably exceeded the standard variety in the first cutting, but in the second cutting their yield was equal to the yield of the standard variety. According to the green mass yield of one cutting, the studied varieties of sainfoin were as good as the alfalfa productivity in the first cutting. The green mass pro­ductivity of the standard variety “Zernogradsky 2” ranged from 24.4 to 31.1 t/ha, the green mass productivity of the sainfoin variety “Veles” ranged from 26.8 t/ha to 39.4 t/ha, and the green mass productivity of the variety “Sudar” ranged from 28.8 t/ha to 33.3 t/ha. The dry matter productivity of the sainfoin varieties developed in a similar way. The minimum dry matter productivity of the standard variety “Zernogradsky 2” was 6.1 t/ha, the maximum was 7.8 t/ha. The minimum dry matter productivity of the variety “Veles” was 6.7 t/ha and the maximum was 9.8 t/ha. The minimum dry matter productivity of the variety “Sudar” was 7.2 t/ha and the maximum was 8.8 t/ha. In total for 2 cuttings, the alfalfa varieties produced 7.45–8.12 thousand of fodder units, 2.29–2.57 t/ha of raw protein and 1.59–1.78 t/ha of digestible protein. The varieties “Lyutsiya” and “Selyanka” showed a higher yield of nutrients, compared with the standard variety. The nutrient productivity of the studied sainfoin varieties slightly yielded to the alfalfa varieties in the first cutting. On average they produced 3.89–4.55 thousand of fodder units per hectare, 1.34–1.55 t/ha of raw protein and 0.93–1.11 t/ha of digestible protein. In comparison with the standard variety “Zernogradsky 2”, the sainfoin varieties “Veles” and “Sudar” had a greater productivity of nutrients.

When creating new varieties, at present, priority is given to obtaining very early and early, in order to expand the conveyer of raw materials for processing. The merits of the breeding achievements created and included in the State Register are shown: a very early variety Prima (year of inclusion 2016) and an early Kudodesnik 2 (2018), which have already begun to be used in production. However, for processing enterprises in each group of ripening it is necessary to have 2-3 varieties. Therefore, we have set a goal - to create new varieties of vegetable peas of very early and early ripening periods, adaptive to the climatic conditions of the North Caucasus region. The studies were carried out from 2016 to 2018 in breeding fields (Krymsk Experiment Plant Breeding Station, VIR, Krasnodar region). Studied 10 varieties and lines. According to the results of evaluation in competitive variety testing (in 2016-2017), a very early grade of vegetable peas Izyuminka was transferred to the state test. The variety ripens 9 days earlier than the Alpha standard and surpasses it in yield (by 2.2 t / ha.). According to the competitive test held in 2017-2018, in 2019, the early variety Mayak was transferred to the state variety testing, which ripens 4 days earlier than the standard and is almost twice as high in yield. The use of these varieties in the processing industry will significantly increase the period of receipt of grain for processing.

Beginning Of Flowering

Alfalfa is the most valuable forage crop spread all over the world. Due to the varietal diversity of alfalfa in the countries of North America, the laboratory of breeding and seed-growing of perennial grasses of the FSBSI “Agricultural Research Center “Donskoy” conducted the experiments over 27 samples of American and Canadian breeding to find genetic sources of economic and biological traits. The field trials were conducted according to generally accepted methods for forage crops in 2016–2018. The area of experimental plots was 1 m2 with double sequence. The period “beginning of spring germination” and “beginning of flowering” were studied depending on the climatic conditions of the year. In 2016 and 2017 spring germination took place in March, and in 2018 it was in the 1-st decade of April. Beginning of flowering in the studied samples ranged from the 3-d decade of May to the 1-st decade of June. On average, over 3 years, the number of days in the period “beginning of spring germination – beginning of flowering” varied from 68 to 73 days. This period of the standard variety was 72 days. The studied samples had this period on 1–4 days shorter, excluding the samples “K-33299” and “K-42249” (73 days). According to the yield of green mass, none of the samples reliably exceeded the standard variety “Rostovskaya 90” (3.29 kg/m2). The studied alfalfa samples formed 1.57–3.5 kg/m2 of green mass. According to the plant foliage amount, the indicators of the studied samples varied from 42 to 49%. The samples “K-33299” and “K-43272” with 49% of foliage amount slightly exceeded the standard variety “Rostovskaya 90” (48%). The hay yield of the studied samples varied from 31 to 40%, “K-43272” formed the smallest indicator (31%), “K-42249” and “K-45715” (40%) produced the largest amount and when the hay productivity of the standard variety was 35%. There have been identified reliable correlations between the yield of green mass and hay, as well as between the yield of green mass and the number of days during the period “beginning of spring germination – beginning of flowering”.
