This chapter focuses on breeding barley for durable resistance to net and spot forms of net blotch. It starts by reviewing how Pyrenophora teres f. teres can cause net form net blotch. The chapter then goes on to examine the molecular markers that can be identified to provide resistances to net form net blotch. A section on the population dynamics of barley–P. teres f. teres interactions is also provided. The chapter also reviews how breeding crops with specific genes can help to create durable resistance to net form blotch. It moves on to discuss how Pyrenophora teres Drechs. f. maculata can cause spot form net blotch and how identifying specific molecular markers can help provide resistance to this form of net blotch. The chapter concludes by highlighting the importance of combining durable resistance to both forms of net blotch.

Ascospore progeny of cross of Pyrenophora teres f. teres isolates was evaluated on virulence to three barley genotypes. Monogenic inheritance of virulence (26 a:17 v and 31 a:18 v) was shown to cultivar Harbin and accession c 21272 and supported by results of two fungal backcrosses. The existence of three unlinked avirulence genes to CI 4922 is suggested (37 a:7 v). The model of interaction between barley resistance genes and avirulence genes with postulated fungal genotypes is proposed.

The distribution in western Canada of three biotypes of Pyrenophora teres, the cause of net blotch of barley, was determined. Two of these produced typical net blotch symptoms but differed in virulence and were found throughout the prairies in 1974. The third, which produces spot-like symptoms, was found only in Manitoba and comprised half the total isolates. The incidence of net blotch was higher in fields of two-rowed than in six-rowed barley. Resistance to the three biotypes of P. teres was found in several barley lines when symptom expression and rate of conidial development on infected host tissue were compared. CI 9214 was superior to CI 5791, the resistance source used in some barley breeding programs.

The review presents the perspectives of using DNA-markers in barley breeding for resistance to toxicity of aluminum, boron, manganese and cadmium ions. Currently, there have been identified quite a number of ion-resistance genes and quantitative trait loci (QTLs). Markers 1 kb-insertion and HvMATE-21indel that are linked to the HvAACT1 gene are recognized as standard gene-specific markers of aluminum resistance. Loci QTLs still require validation, but in the future they can serve as a basis for pyramiding several loci of aluminum tolerance in a single genotype. Molecular markers specific to the boron resistance genes of barley (HvBot1, HvNIP2;1 and HvBot2), and the QTL of barley resistance to the manganese toxicity (QSur.yf.3H) have also been developed. QTLs, genes, and markers related to low cadmium accumulation were identified in barley. Most studies focus on finding and developing markers linked to ion resistance rather than on their practical application in plant selection. However, breeding programs have already used markers related to the resistance of barley to high concentrations of aluminium and boron ions. Marker-assisted selection has high potential, and in course of time advances in science make its technologies more accessible, easier, and less expensive.
