The current paper has presented the study results on the ecological estimation of seed peas of different types of development. The purpose of our study was to assess the quantitative and qualitative indicators of seed peas varieties of different types of development in the southern part of the Rostov region. The trials were carried out on the experimental plots of the FSBSI “Agricultural Research Center “Donskoy” at the laboratory for legumes breeding and seed production. Autumn sowing was carried out in the second decade of October. Spring sowing was conducted in the third decade of March. The objects of the study were the variety ‘Legion’ sown in autumn and spring in comparison with the variety ‘Aksaysky Usatiy 5’, which was used as a standard variety in the trials. The statistical data were processed according to B. A. Dospekhov’s methodology (2012) using Excel with the STATISTICA 10 application. The variety ‘Legion’ sown in autumn ripened earlier in comparison with the standard variety ‘Aksaysky Usatiy 5’. Early ripening of winter peas than spring peas made it possible to evenly distribute the load on the harvesting equipment, since ripening of spring peas often coincided with ripening of winter grain crops, such as winter barley and winter wheat. The variety ‘Legion’ sown in winter exceeded the standard variety ‘Aksaysky Usatiy 5’ in such indicators as “plant height”, “number of beans”, “number of seeds”, “seed weight per plant” and “protein percentage”. The study results have shown that the conditions of the southern part of the Rostov region were favorable for the cultivation of winter peas. The winter peas ripened a decade earlier than spring peas, and seed productivity was 1.7–1.8 times larger.

The improvement of yield stability largely depends on responsiveness to favorable growing conditions and resistance to stress factors. The promising varieties should have stable yields, resistance to unfavorable environmental conditions, such as winter resistance and drought tolerance. In this regard, a purposeful breeding for adaptability, i.e. resistance to stress factors is of great importance. The purpose of the research was to study the adaptability and stability of winter barley varieties. The estimation was carried out on the experimental field of the FSBSI ARC “Donskoy”, which is located in the southern zone of the Rostov region. Through three years, 28 winter barley varieties of domestic and foreign breeding were studied. The location of the plots is systematic in double sequence; the area is 10 m². The calculation of ecological plasticity was carried out according to the method of S. A. Eberchart, W. A. Rassel (1966) (ed. by V. A. Zykin (2005)) using the statistical data processing program Statistica 10. It has been established that the most responsive varieties (bi > 1) to the improvement of growing conditions were ‘Erema’ (bi = 1.60), ‘Foks 1’ (bi = 1.64), ‘Skala’ (bi = 1.61), ‘Explorer 8’ (bi = 1.81) and ‘Capten’ (bi = 2.02). These varieties due to a high level of agricultural technology provide maximum yields. At an extensive background it is better to use the varieties ‘KWS-2-117’ (bi = 0.28), ‘KWS – 2–234’ (bi = 0.48). The most stable varieties of the studied foreign ones were the varieties ‘Wintwalt’ and ‘Explorer 4’ (σ²d = 0.04). Through the years of study, the variety ‘Marusya’ (RF) had the highest yield with a linear regression coefficient bi = 0.54, which indicates great stability of this variety.
