STUDY OF COLD RESISTANCE OF BUCKWHEAT VARIETIES OF THE BELARUSIAN BREEDING AT THE JUVENILE STAGE OF DEVELOPMENT UNDER IN VITRO CONDITIONS FOR FORMING ADAPTIVE VARIETAL POPULATIONS
The article presents the results of studying buckwheat cold resistance at the juvenile stage of development It’s established that the best way to sterilize buckwheat seeds is a 10-15 minute treatment in 94% sulphuric acid. The optimum temperature for cold resistance selection is +5 °С. The studied buckwheat varieties differed significantly in terms of the degree of cold resistance, at the same time even low cold-resistant samples had single resistant genotypes. The maximum number of germinated plants and a greater percentage of seedlings with a germinal root length of 1 cm or more were observed on the Ъ MS medium without additives (control) and light and Ъ MS +2 mg/l IBA without light.
