Estimation of drought resistance in various by origin genotypes of buckwheat (Fagopyrum esculentum Moench.)

Abstract

The article deals with studying of collection samples by
fruitful characteristics and morphological indicators in
contrast conditions of environment. The hydrothermal
coefficient was used as an additional index of cultivation
conditions. Tolerance degree to action of extreme
conditions of various characteristics of a vegetative
organism is defined. Among studying group of
buckwheat the genotypes have been picked out with the
improved ability to adaptation in enough droughty
conditions which are valuable initial material for
selection of highly productive grades with considerable
potential of stability to a drought.
