Abstract

In hybrids of spring barley, variability and degree of symptoms that determine the yield are determined in a wide range of eco-geographical zones. It has been found that the degree of variability of major quantitative traits in hybrids of barley increases in more favorable conditions where the entire genetic potential of the hybrid is manifested most widely. An insignificant difference was noted in the variation of the weight of 1,000 grains, the number of grains per spike, and grain weight in the head, depending on the zone of cultivation. Locally adaptive and ecologically plastic hybrids that may be used as initial forms for hybridization were selected
