“…Так, высокая температура воздуха в период вегетации суданской травы ускоряет развитие растений, в результате чего происходит более быстрое созревание семян. Однако без осадков это зерно будет щуплым и, следовательно, урожайность получим ниже [7,20].…”

Productivity of any crop is the potential of the variety when interacting with environmental factors, and especially meteorological ones. Losses due to unfavorable conditions in some years can be up to 50-65,0 %. The purpose of the work was to identify how the productivity of Sudan grass green mass varied through the years with different meteorological conditions, which factors had the greatest effect on it. The study was carried out in 2012-2021 in the conditions of Rostov region. The soil of the plot was ordinary carbonate chernozem. The object of the study was the Sudan grass of Alisa variety, introduced into the State List of Breeding Achievements in 2019. Differences in sowing dates (I-II decades of May) had no effect on green mass productivity and the time of grain maturing. The Sudan grass green mass productivity varied significantly from 36 t/ha to 43 t/ha through the years of study. The year of 2021 was more favorable both in temperature and moisture supply for the formation of the first cut of green mass, and the year of 2018 was favorable for the formation of the second one. The first cut of the green mass was more important and productive. The second cut productivity in 2018 was 84.5 % of the first cut and 45.8 % of the amount of both cuts. In 2021, 35,0 % of the first cut and 26.5 % of the total productivity. The correlation analysis has confirmed that green mass productivity has a close positive correlation with the amount of precipitation (r = 0.79) and a mean negative one with the average air temperature during the vegetation period (r = -0.59).

BACKGROUND: Russia is one of the largest peanut-buying countries. At the same time, in the south of the country, a number of zones meet the requirements for the cultivation of peanuts. AIM: Identification of a new source material for peanut breeding by the method of ecological and geographical testing of collection samples. MATERIALS AND METHODS: The work used 30 of peanuts accessions from the VIR collection of various origins. To assess the stability of productivity, standard deviation (s), coefficient of variation (Cv) and regression (i) for environmental conditions according to Eberhart and Russell were used. RESULTS: As a result of the study, the possibility of growing individual varieties of peanuts in the south of the RF under modern conditions was confirmed. It was determined that some samples are more productive and suitable as starting material for the conditions of the Krasnodar Territory (k-283, k-1157), others for the conditions of the Astrakhan region (k-317, k-868). The accessions of the VIR collection were found to be more productive at 2 points experience, also marked as plasticity k-751, k-283, k-626, k-1533, k-1987. CONCLUSIONS: In contrasting conditions (two geographical points for 3 years of study), peanuts accessions were identified that strongly react to changes in environmental conditions. Stable and plastic in productivity accessions can serve as the initial breeding material. It has been established that peanuts can be cultivated in the south of the Russian Federation, namely in the Astrakhan Region and the Krasnodar Territory.

Sorghum is one of the most adaptable and undemanding forage crops cultivated in arid zones. The crop is characterized with high quality foliage, which can be used in fodder production in various forms (both in single-crop silage and in multi-crop mixtures). The purpose of the current study was to estimate the variability of the main productivity elements of sweet sorghum green mass depending on weather indicators. The initial material was presented by 180 collection samples of sweet sorghum from Russia, the USA and Ukraine. There have been used conventional breeding methods, such as hybridization, selection and inbreeding. The weather conditions during the study years of 2017–2021 were contrasting. The hydrothermal coefficient for the vegetation period of sorghum indicates that the year of 2018 was the driest one (HThC = 0.38). The variability coefficient of collection samples of sweet sorghum according to green mass productivity has shown a strong variability of this indicator (V = 27–35%). The green mass productivity had a close direct correlation with the length of a leaf (0.73±0.05) and an average correlation with its width (0.61±0.06). The variability coefficient has shown that the samples of sorghum collection had an average variability according to the traits ‘leaf length’ (V = 15.3%) and ‘leaf width’ (V = 11.8%), and were stable according to the trait ‘number of leaves per plant’ (V = 7.4%). Correlation and regression analysis has shown that ‘leaf length’ had an average inverse correlation with air temperature (r = –0.42±0.06) and a strong direct correlation with precipitation (r = 0.78±0.05). The trait ‘leaf width’ is practically independent of weather conditions. The number of leaves had an average negative correlation with air temperature (r = –0.55±0.06), and a weak correlation with amount of precipitation. A leaf length and width are marker indicators of high productivity, so they can be used in plant selection for productivity.
