Drought represents the most devastating abiotic stress factor worldwide. It severely limits plant growth and development as well as agricultural characteristics including the final yield. The aim of this review is to summarise recent results of the breeding of barley (Hordeum vulgare) and wheat (Triticum aestivum; T. durum) for improved resistance to drought stress. First, drought-associated terms and definitions are outlined and plant strategies to cope with drought are presented.

Barley (Hordeum vulgare L.) is produced in the Ecuadorian highlands ( > 3,000 m a.s.l.) primarily for self-consumption and small-scale commercialization. Not many crop species are adapted to this altitude; therefore, barley is one of a few crop species that can be grown at these locations. Severe environmental conditions can be found in the Ecuadorian highlands since the region is characterized by poor soils and water deficiency (< 300 mm yr-1).

AbstractSince the 1980s, Ramularia leaf spot (RLS) is an emerging barley disease worldwide. The control of RLS is increasingly aggravated by a recent decline in fungicide efficacy and a lack of RLS-resistant cultivars. Furthermore, climate change increases drought periods in Europe, enhances variable weather conditions, and thus will have an impact on severity of plant diseases. Hence, identification of RLS-resistant cultivars and understanding of disease progression under abiotic stress are important aims in integrated disease management under climate change.

An effective way to increase the genetic diversity of plants and create sources of resistance to edaphic stressors is the selection of cells under selective in vitro conditions based on somaclonal variation. The use of somaclones (regenerant forms) of barley with resistance to increased acidity, ionic toxicity of aluminum, heavy metals and drought is promising in the northeast of the Non-Black-Soil Zone of Russia. Development of regenerants with integrated resistance to soil stressors due to specific and nonspecific mechanisms is a relevant trend.The target research material was a hybrid combi

One of ways to increase resistance of agricultural plants to abiotic stresses is the use of biofertilizers with anti-stress and growth-regulating properties. They improve absorption of nitrogen and phosphorus from organic fertilizers and soil.

Spring barley is a key grain-fodder and fodder crop, which forms an increased yield compared to other grain-fodder crops due to early maturity and drought resistance. Taking into account climatic factors and production demands, breeding for increased productivity and adaptability to local natural and climatic factors, resistance to biotic and abiotic stresses is relevant today.

The improvement of yield stability largely depends on responsiveness to favorable growing conditions and resistance to stress factors. The promising varieties should have stable yields, resistance to unfavorable environmental conditions, such as winter resistance and drought tolerance. In this regard, a purposeful breeding for adaptability, i.e. resistance to stress factors is of great importance.

Modern investigation techniques (e.g., metabolomic, proteomic, lipidomic, genomic, transcriptomic, phenotypic), allow to collect high-dimensional data, where the number of observations is smaller than the number of features. In such cases, for statistical analyzing, standard methods cannot be applied or lead to ill-conditioned estimators of the covariance matrix. To analyze the data, we need an estimator of the covariance matrix with good properties (e.g., positive definiteness), and therefore covariance matrix identification is crucial.

Mildew resistance locus O (Mlo) gene was first found in barley as a powdery mildew susceptibility gene, and recessive mlo alleles confer durable resistance to barley powdery mildew. To identify candidate Mlo susceptibility genes in rubber tree, HbMlo12 was cloned from rubber tree clone CATAS7-33-97, which is susceptible to powdery mildew. Protein architecture analysis showed that HbMlo12 was a typical Mlo protein with seven transmembrane domains. Protein blast search in the Arabidopsis thaliana proteome database showed that HbMlo12 shared the highest similarity with AtMlo12, with 63% sequence
