“…); barley rusts; viruses such as barley yellow dwarf virus (BYDV); and pests, particularly aphids, beetles, and nematodes. The disease incidence depends directly on a few factors, including local climate, geography, soil type, prevailing agricultural practices, and plant age [ 171 ]. To minimize yield loss resulting from biotic stress, various disease-resistant varieties were created by introduction of resistance genes; however, due to the ever-present “arms race” between plants and pathogens and the resulting evolution of pathogens, this approach has proved to be ineffective in long term in many cases, such as that of wheat [ 172 ].…”

Therefore, in order to get a solution that works in the long run, more integrated molecular approaches for developing high-yielding barley varieties with enhanced durability and broad-spectrum disease resistance have to be applied [ 171 ].…”

Abscisic acid (ABA) is well-known phytohormone involved in the control of plant natural developmental processes, as well as the stress response. Although in wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) its role in mechanism of the tolerance to most common abiotic stresses, such as drought, salinity, or extreme temperatures seems to be fairly well recognized, not many authors considered that changes in ABA content may also influence the sensitivity of cereals to adverse environmental factors, e.g., by accelerating senescence, lowering pollen fertility, and inducing seed dormancy. Moreover, recently, ABA has also been regarded as an element of the biotic stress response; however, its role is still highly unclear. Many studies connect the susceptibility to various diseases with increased concentration of this phytohormone. Therefore, in contrast to the original assumptions, the role of ABA in response to biotic and abiotic stress does not always have to be associated with survival mechanisms; on the contrary, in some cases, abscisic acid can be one of the factors that increases the susceptibility of plants to adverse biotic and abiotic environmental factors.

“…It is resistant to harsh environmental conditions, such as soil salinity, high altitude and low rainfall (von Bothmer et al 2003a), and is used for feeding and malting purposes. The challenge is to control over 250 pathogens infecting the barley crop (Singh et al 2019). Most of them are a significant economic problem through reduction of the crop quality and yield.…”

Barley (Hordeum vulgare L.) is one of the most widely grown cereal crops. Numerous pathogens impair the amount and quality of the grain yield. Blumeria graminis f. sp. hordei (Bgh) is a fungal pathogen causing powdery mildew, a widespread and economically important foliar disease. Since there is a limited number of known resistance genes, efforts of scientists and breeders are focused on searching for new sources of resistance. Barley landraces are a known, but still underexploited source of diversity. A set of 79 barley landraces collected in North Africa and the Middle East was tested against powdery mildew at seedling and adult plant stages. Under a controlled environment, 50% of accessions showed resistance conditioned by major genes. Among them, seven accessions showed broad resistance to Bgh isolates that were virulent to most of the known resistance genes. The field experiments carried out under natural infection over several years indicated all accessions as potential sources for resistance breeding. Twelve landraces were found to be medium resistant or resistant during all six seasons. This report relates to barley landraces as a promising source of potentially novel resistance to powdery mildew.

Jęczmień (Hordeum vulgare L.) jest jednym z najważniejszych gospodarczo zbóż i zajmuje czwarte miejsce pod względem areału upraw na świecie. Mączniak prawdziwy, powodowany przez grzyb patogeniczny Blumeria graminis f. sp. hordei, jest jedną z najważniejszych chorób wpływających negatywnie na ilość i jakość plonu jęczmienia. Ograniczona pula genów odporności wykorzystywanych w odmianach uprawnych stwarza potrzebę poszukiwania i identyfikacji nowych źródeł odporności.
