Adaptability indicators of the lotus corniculatus in the conditions of the Non-Chernozem zone of Russia

Abstract. The purpose of the research is to conduct a comparative study lotus corniculatus samples with Smolenskiy 1 standard, as well average yield green mass according experience. It necessary identify most productive and adapted conditions Smolensk region variety numbers for further transfer next stage breeding study. scientific novelty work lies in fact that results adaptability terms were studied first time nursery Federal Research Center Bast Fiber Crops on crops. Methods. indices plasticity (bi), stability (Sd2), genetic flexibility ((Ymin + Ymax)/2), stress resistance (Ymin – Ymax), coefficient variation (V), (CA), equalization (E), range (d). soil site sod-medium podzolic an humus content 2.3, P2O5 222–240 mg/kg, K2O 102–170 mg/kg soil, salt extract pH 4.9–5,4. Weather climatic 2017–2020 different, so HTC 1,2–2,4; SAT 2200–2400 °C. Results. Of 16 cultivars, E-25 (59.3 t/ha) E-49 (48.1 t/ha). E-8, E-11, 1, E-6, E-9, E-50 have increased (–18.8 ...–28.8 best indicator E-25, E-10, E-16 (52.4 t/ha, 48.8 t/ha 45.5 plastic are E-19 (1.09), (1.05), E-26 (1.02), E-6 (0.99). In experiment, (6.27), E-47 (7.67), (8.43) (8.47) more stable. High was shown by KA = 1.31...1.06. E-12, E-47, E-16, good agronomic stability, E 80.4...70.1%. A comprehensive analysis indicators made it possible valuable cultivar reproduction study: E-19, E-26, E-49.
