“…In connection with changing climatic conditions, there is a need to create and introduce into agriculture more resistant spring barley varieties with high productivity and grain quality. The combination of such properties in one genotype can only be obtained with a special selection of pairs for crossing and the use of field and laboratory methods for assessing the source material in the selection process [11][12].…”

One of the main conditions for the stable growth of grain production of spring barley is the expansion of sown areas, using varieties with high adaptive properties and capable of providing high yields in a changing climate. The purpose of the work is to determine the drought resistance and heat resistance of varieties and lines of spring barley using laboratory methods. The article presents studies of physiological indicators of resistance at an early stage of plant development to extreme environmental factors (drought and relatively high air temperatures). The physiological method of early diagnostics of seeds and seedlings provides information on the general initial level of physiological and biochemical processes in germinating seeds under stressful conditions and allows one to get an idea of the resistance of adult plants. Such a primary assessment gives grounds for the selection of promising samples for a deeper study of their stability. When determining the resistance of varieties and lines of spring barley to abiotic stressors, samples were identified that, in terms of a set of indicators (drought resistance, heat resistance, degree of depression, index of complex resistance and growth of germinal roots), values significantly exceeding the standard variety Ratnik (36.6; 91, 1; 2.13%; 184.3 rel. units and 2.78 cm, respectively): Zernogradsky 1717 (45.6; 84.0; 5.19%; 194.8 rel. units and 4.76 cm), Zernogradsky 1716 (4.3; 83.4; 5.43%; 188.0 relative units and 3.67 cm), Zernogradsky 1701 (36.2; 87.0; 3.17%; , 4 relative units and 2.56 cm).

“…in the Fertile Crescent [2]. It is an important crop, especially in areas where wheat cultivation is not feasible, thanks to some of its characteristics such as greater environmental adaptability, lower water requirements, tolerance to stress conditions, and ability to grow in either saline [3] and alkaline soils [4]. Barley has several applications, e.g., as seed in the malting industry and as livestock feed as a whole plant for hay, silage, green feed, or even as straw [5].…”

Over two cropping seasons, 2017/18 and 2018/19, an experimental trial was conducted in a typical cereal-growing environment of the Calabrian hills (southern Italy) to study seeding rate (D) and nitrogen fertilization (N) effects on two barley F1 hybrids (Zoo and Jallon) compared to those of a traditional variety (Lutece), assessing the bio-agronomic response. Barley hybrids, gradually introduced into the principal European countries starting in 2010 as winter forage, currently represent a significant part of the EU internal market. Productive performance was evaluated as grain yield for feed and total biomass for silage and/or biogas production. Research results pointed out the greater performance of barley hybrids compared to conventional varieties in terms of both grain and biomass production. On average, barley hybrids vigour mainly manifested itself through a high tillering and a greater number of ears m−2 compared to those of the conventional variety (+24 and +23%, respectively). Furthermore, barley hybrids were characterized by a greater 1000-kernel weight and hectolitre weight than those of the Lutece variety (conventional variety). A significant increase in grain production was observed, increasing density from D150 to D225 rates (+35% and +33%, respectively) which was followed by a decrease in production shifting from D225 to D300 doses. A significant increase in biomass production was as well highlighted for the two hybrids, shifting from D150 to D225 rates (+26% and +27%, respectively). The applied nitrogen dose highlighted a different behaviour between the hybrids and the conventional variety; in particular, the lowest nitrogen dose (N80) negatively influenced the Lutece variety both in terms of grain and biomass production (−9% and −16%, respectively) while the hybrids showed the best agronomic response even at the lowest dose. On average, with the N80 dose, grain yield of Zoo and Jallon was greater than 20% and 16%, while with the N120 dose grain yield was 9% and 7%, respectively. A similar behaviour was found for biomass yield. It should therefore be emphasized that barley hybrids possess high yielding capacities and that such higher grain production can be achieved in a Mediterranean environment by using a lower seed rate (approximately −25%) and a reduced nitrogen dose (approximately −33%) compared with those commonly applied to conventional varieties.
