Selection Value Of Tomato Varieties And Lines According To The Set Of Cold Resistance And Adaptability Traits

Abstract

The paper reveals the results of research on the adaptive capacity of cold resistance traits in tomato varieties, which were studied in the field and laboratory conditions. The level of general and specific adaptive capacity and homeostatic cold resistance was determined. Valuable source material was selected on the basis of traits characterizing the cold resistance in the field and laboratory conditions. Valuable varieties with a high level of adaptability on the grounds of cold resistance - seed germination, plant height increase, growth rate, duration of the sowing-germination period were identified.
