Investigation of the cold resistance of winter six-row barley (Hordeum vulgare L.) varieties
Marina Marcheva, Velichka Koteva
Резюме: Abstract
The cold resistance of nine Bulgarian and foreign varieties six-row winter barley (Hordeum vulgare L.) has been investigated. In laboratory trial express methods for cold resistance based on the depression of root and shoot in low temperatures of has been used. The real winter hardiness and the production of grain yield in natural field conditions in 3 years have been calculated. The analogy in the results and the genotype’s clustering prove the possibility for using this time – and consummative - saving method in the early plant breeding for cold resistance.
