Abstract. Barley is an important crop in Trakia region, Turkey and due to various environmental factors it can suffer some biotic stress and yield loss in the region. This research was carried out in two locations (Edirne and Tekirdağ) of Trakia region during 2013-2014 growing year. The experiment was set up with 25 advanced genotypes in completely randomized blocks with four replications at two locations. Grain yield, plant height, days to heading, leaf rust, net blotch, powdery mildew and relationship among these characters were investigated. According to the results, there was significant difference among genotypes for grain yield, biotic stress factors and other characters. The mean grain yield of the genotypes was 6866 kg ha-1. TEA1619-11 had the highest grain yield with 7667 kg ha-1. TEA2311-19 (7593 kg ha-1) and Harman (7593 kg ha-1) were the other highest yielding genotypes. Due to various environmental conditions, there was significant difference between locations. Mean yield in Edirne location was 7841 kg ha-1 and in Tekirdağ location it was 5891 kg ha-1. TEA1619-8 and TEA1619-9 sister lines had the shortest plant height and early genotypes had higher grain yield. Net blotch (Pyrenophora teres f. teres) is the mainly prevalent disease in Trakya region. Leaf rust and powdery mildew had negative effect and decreased grain yield. TEA1619-12, TEA1619-17, TEA2311-19 and TEA1980-25 genotypes were resistant at both locations. TEA1980-25 was an outstanding line to net blotch, leaf rust and powdery mildew. It was determined that increase of net blotch had negative effect and decreased the grain yield in the genotypes.

Biotic Stresses

Abiotic and biotic stresses adversely affect rice growth, development and grain yield. Traditional rice breeding techniques are insufficient in modern agriculture to meet the growing population’s food needs on a long-term basis. The development of DNA markers closely linked to target genes or QTLs on rice chromosomes, and advanced molecular techniques, such as marker-assisted selection (MAS), have encouraged the evolution of contemporary techniques in rice genetics and breeding, such as gene pyramiding. Gene pyramiding refers to the act of combining two or more genes from multiple parents into a single genotype, which allows the overexpression of more than one gene for broad-spectrum abiotic and biotic stress resistance. Marker-assisted pedigree, backcrossing and pseudo-backcrossing methods can increase the conventional breeding speed by reducing the number of breeding generations in order to enhance the pyramiding process. Pyramiding is affected by several factors: the number of transferred genes; the range within gene and flanking markers; the number of chosen populations in every breeding generation; the features of genes and germplasms; and the potentiality of breeders to identify the target genes. Modern breeding methods, such as the marker-assisted backcrossing approach, have made gene pyramiding more precise and reliable for the development of stress-tolerant rice varieties in the coming decades. This review presents up-to-date knowledge on gene pyramiding schemes, marker-assisted gene pyramiding techniques, the efficiency of marker-assisted gene pyramiding and the advantages and limitations of gene pyramiding methods. This review also reports on the potential application of marker-assisted selection breeding to develop stress-tolerant rice varieties that stabilize abiotic and biotic stresses. This review will help rice breeders to improve yields by increasing rice productivity under abiotic and biotic stress conditions.

Twelve articles (ten research papers and two reviews) included in the Special Issue entitled “Wheat and Barley: Acclimatization to Abiotic and Biotic Stress” are summed up here to present the latest research on the molecular background of adaptation to environmental stresses in two cereal species. Crucial research results were presented and discussed, as they may be of importance in breeding aimed at increasing wheat and barley tolerance to abiotic and biotic stresses.
