A quantitative trait loci (QTL) regulating early flowering in barley (Hordeum vulgare L.)

Spatial environmental variability, including changes in climate to frost, heat and extreme drought frequencies is penalising yield of barley. To achieve higher yield and improved grain quality, genotypes must be highly adaptable to the changing environment. Identification and understanding the genetic factors and their complex interactions with environment regulating heading date will help barley crop adaptation and consequently increase yield gain and improve grain quality.
