VASILEVA, S. and M. MARCHEVA, 2016. Genetic analysis of productivity components in malting barley (Hordeum vulgare, L.) hybrid progenies. Bulg. J. Agric. Sci., 22: 452–457 The investigation was conducted on the experimental fi eld of the Agricultural University of Plovdiv, during the period 2011–2014. Coeffi cients of heritability and selection, the number of genes, transgressions and heterosis in relation to maintraits, determining productivity in malting barley crosses were studied. For this purpose biometrical data of P1, P2, F1 and F2 populations of four hybrid combinations were used. Hybridological analysis data of studied barley populations showed that the inheritance of some traits as plant height, productive tilling, main spike lenght, number of spiklets and grains, grains weight on spike and 1000-grain weight is mainly overdominant in direction of the higher trait values. Parental genotypes Kaskadior, 96105046, 96105023, Emon, 96105027 and 96105024 differ in a small number of genes affecting expression of productive tillering and grains weight on the spike. Based on the conducted analysis it was found that the mass selection by phenotype for main spike lenght, number of spiklets and grains and 1000-grains weight would be more effective in earlier hybrid generations (F2-F3).

Quantitative Trait Loci and Maternal Effects Affecting the Strong Grain Dormancy of Wild Barley (Hordeum vulgare ssp. spontaneum)
Wild barley (Hordeum vulgare ssp. spontaneum) has strong grain dormancy, a trait that may enhance its survival in non-cultivated environments; by contrast, cultivated barley (Hordeum vulgare ssp. vulgare) has weaker dormancy, allowing uniform germination in cultivation. Malting barley cultivars have been bred for especially weak dormancy to optimize their use in malt production. Here, we analyz...
متن کاملGenome-Wide Association Mapping for Kernel and Malting Quality Traits Using Historical European Barley Records
Malting quality is an important trait in breeding barley (Hordeum vulgare L.). It requires elaborate, expensive phenotyping, which involves micro-malting experiments. Although there is abundant historical information available for different cultivars in different years and trials, that historical information is not often used in genetic analyses. This study aimed to exploit historical records t...
متن کاملComparative Proteomic Analysis of Two Barley Cultivars (Hordeum vulgare L.) with Contrasting Grain Protein Content
Grain protein contents (GPCs) of barley seeds are significantly different between feed and malting barley cultivars. However, there is still no insight into the proteomic analysis of seed proteins between feed and malting barley cultivars. Also, the genetic control of barley GPC is still unclear. GPCs were measured between mature grains of Yangsimai 3 and Naso Nijo. A proteome profiling of diff...

In order to determine the heritability and genetic parameters of some agronomic traits in barely (Hordeum vulgare L.) cultivars, a seven-parent half diallel (F1 crosses + parents) was conducted in the non-stress and salt stress (8 and 12 ds m-1) conditions in a randomized complete block design with three replications. Genetic analysis was performed by Hayman’s method and Griffing’s fixed model,...
