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.

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.

OAC Elmira is a high-yielding, disease-resistant, hardy winter barley adapted to Southern Ontario. OAC Elmira has good winter hardiness and high hectoliter weight. It has better disease resistance than any of the check cultivars and long straw with a lax, nodding head. It was developed by the Ontario Ministry of Agriculture and Food through the Crop Science Department of the University of Guelph. Key words: Hordeum vulgare L., high yield, disease resistance, winter hardiness
