“…According to Tinker et al (1996) Estimates of broad-sense heritability for barley grain yield, varied considerably in the literature, probably due to differences in the type of genetic material and the environments where the studies were performed. Some authors reported high or moderate values (Addisu et al, 2015;Akgün, 2016;Sunil and Khan, 2017) while others found low estimates (Ahmadi et al, 2016) for this trait.…”

The aim of the present study was to use REML/BLUP-based procedures in order to estimate variance components and genetic parameters and to determine correlations between grain yield and yield-related traits of winter barley varieties. Studied genotypes were grown in two seasons characterized by different levels of water deficit (precipitation sum was less by 15% in the first growing year and 36% in the second growing year than the long-term precipitation sum). A reduction was observed in all studied yield-related traits, with grain yield in the second year being more than 70% lower than that measured in the first growing year. Lower values of broad-sense heritability in the second growing year for the traits number of spikelets and grains per spike, grain weight per spike, and grain yield were found suggesting that the direct selection of these traits under drought stress conditions will be less effective. Varieties ranking based on the FAI-BLUP index strongly varied across growing seasons, but in both years variety Bojin was selected as a highperforming variety for multiple traits. Considerable differences were observed in the magnitude and directions of correlations between grain yield and yield-related traits between two growing seasons. These findings, in the context of the increasing frequency and duration of drought stress in the region, suggest a longer period of multi-year testing and complicate the process of selection in breeding programs of winter barley.

“…The genetic variation between cultivars of barley and their related wild species easily gives way to use for the hybridization process in plant breeding. Barley has become a model plant experimental system for much scientific research around the world [11][12][13][14][15][16][17][18].…”

Barley (Hordeum vulgare L.) is an important cereal crop around the world and is of major importance to many countries [1][2]. In terms of global acreage and production, barley is the fourth major cereal crop after wheat, rice and corn globally [3], and is regarded as one of the most tolerant crops for drought and alkaline soils, and it has the highest water-use efficiency compared to other cereal crops, but it is less tolerant to acidic soils [4][5][6][7].Cultivation conditions of barley genetic diversity are essential for adapting to future environmental changes,
