Significant Yield

Five winter barleys (Hordeum vulgare L.) of interspecific origin were crossed onto five local strains of spring barley, and F1 progeny which were evaluated under solid-seeded and spaced-planted arrangements were compared with their spring parent for yield and seed size. No significant yield advantages were detected under solid seeding. Under spaced planting, 12 of 23 hybrids significantly outyielded their respective spring parents. The levels of yield advantage, which exceeded 100% in some cases, were attributed to the genetic diversity of the parents. There was no relationship between performance of hybrids at the two rates of planting. No significant seed size advantage was observed in any of the hybrids.

The Difference

A large number of resistances to powdery mildew (Blumeria graminis f.sp. hordei) and their combinations are known in barley (Hordeum vulgare L.). A similarity of resistance spectra between cultivars carrying the resistance Bw, designated for the winter barley cultivar Borwina, and the near-isogenic spring barley line P15, which carries the resistance Ru2, derived from the landrace Rupee, was found. The objective of this study was to test the difference between resistances Bw and Ru2. Six cultivars were tested, four with Bw and two with Ru2. Testing with 40 isolates showed identical reaction spectra between both groups. Testing of the cultivar Kompolti 4 (Bw) and line P15 (Ru2) with 300 isolates confirmed this result. Thus, the resistances currently designated Bw and Ru2 can be regarded as identical, and are determined by the gene Ml(Ru2). Both Bw and Ru2 should be designated by the earlier code, Ru2.

Aim. The aim of the study was to investigate the varieties of hordein loci of spring barley suitable for cultivation in Ukraine. Methods. To identify the genotype by the loci of the hordein, we used the method of separating the hordeins in polyacrylamide gel (PAAG) in acidic medium by the Brzezinski method with modifications. Results. In 26 varieties of spring barley, genotypes were identified by the hordein loci of Hrd A, Hrd B and HrdF. Differences between alleles of storage protein loci were found in the frequency with which they were distributed among varieties. Conclusions. Found a high level of allelic variability. In barley varieties there is a tendency for the distribution of certain alleles of loci of hordein storage proteins of barley: Hrd A (A2,A4, A12,A18, A23, A32), Hrd B (B1, B5, B6, B8, B17, B19, B21,B29, B35,B67, B164, ), Hrd F (F1, F2, F3, F0).

Seed longevity of 76 spring barley gene pool samples (Hordeum vulgare L. subsp. distichon, convar. distichon: 56 nutans Schubl., two deficience (Steud.) Koern., two erectum Rode ex Shuebl., two medicum Koern.; convar. nudum (L.) A.Trof.: one nudum L. та subsp. vulgare: convar. vulgare: nine pallidum Ser., three rikotense Regel.; convar. coeleste (L.) A.Trof.: one coeleste (L.) A.Trof.) from 26 countries, 11 years and four places of reproduction was analyzed. Seeds with 5–8% moisture content were stored in chamber with unregulated and 4oC temperature. The possibility of seed storage under these conditions for at least 10 years without significant changes in germination has been established. The importance of meteorological conditions in the formation and ripening of seeds for their longevity is confirmed. The relationship between the decrease of barley seeds longevity and storage conditions, amount of rainfall, temperature regime during the growing season of plants is discussed.

Breeding Material

Determination of genetic diversity and population structure of breeding material is an important prerequisite for discovering novel and valuable alleles aimed at crop improvement. This study’s main objective was to characterize genetic diversity and population structure of a collection representing a 40-year long historical period of barley (Hordeum vulgare L.) breeding, using microsatellites, pedigree, and phenotypic data. The set of 90 barley genotypes was phenotyped during three growing seasons and genotyped with 338 polymorphic alleles. The indicators of genetic diversity showed differentiation changes throughout the breeding periods. The population structure discriminated the breeding material into three distinctive groups. The principal coordinate analysis grouped the genotypes according to their growth habit and row type. An analysis of phenotypic variance (ANOVA) showed that almost all investigated traits varied significantly between row types, seasons, and breeding periods. A positive effect on yield progress during the 40-year long breeding period could be partly attributed to breeding for shorter plants, which reduced lodging and thus provided higher yield stability. The breeding material revealed a considerable diversity level based on microsatellite and phenotypic data without a tendency of genetic erosion throughout the breeding history and implied dynamic changes in genetic backgrounds, providing a great gene pool suitable for further barley improvement.
