Adaptive variability of basil cultivars (Ocimum basilicum L.)

Purpose of the research was to estimate state varietal resources and adaptive-and-productive potential basil plants. Methods. Field, laboratory, statistical calculation-analytical. The field work included marking out experimental plot work. laboratory method used analyze plants, assess quality crop, study physical, chemical microbiological properties soil. Statistical analytical calculation methods were calculate results. Results. varieties ‘Temnyi Opal’, ‘MFI-2’, ‘Siaivo’ ‘Badioryi’ where regression coefficient in range 0.57–0.78 can be group highly plastic by “commodity yield” feature according results research. highest rate breeding value “plant weight” trait observed variety Sc = 347.22. on basis ‘Mister Barns’, ‘Rutan’, ‘Badioryi’, 0.91–0.99. ‘Yerevanskyi’, ‘Ametyst’ ‘Lymonnyi Aromat’ classified as intensive. these 1.03–1.16. analysis combination high productivity, quantitative characteristics crop structure with level ecological plasticity stability indicates different ways indicators formation separate varieties. It revealed that a yield did not guarantee similar result some features its structure. Conclusions. degree adaptability also assessed parameters variation. obtained will allow more objectively assessing qualitatively selecting initial forms for further adaptability.
