Opis:: The usefulness of mutagenic treatment to enlarge isozymic variability of barley and the use of induced mutants for genetic analysis were evaluated. N-methyl-N-nitroso urea, sodium azide and gamma rays were employed as mutagenic agents. Electrophoretic assays of 3848 M₂ seedlings obtained by chemical mutagenic treatment of the spring barley cultivars Dema, Aramir, Bielik and 3100 M₂ seedlings obtained by physical mutagenic treatment of the cv. Dema revealed 70 isozymic mutants, which represent 30 separate mutants in 25 M₁ plants. Most of mutations (27) were induced by chemical mutagen at polymorphic esterase loci. The occurrence of induced mutants at monomorphic loci, Got2 and Lap2, made it possible to perform genetic analysis of those loci in barley including mapping respective genes within chromosomes.

Opis:: Hordein polypeptides patterns of 146 mutants in M7 from a hulless spring barley breeding line were examined. The mutants were obtained after treatment of grains of Polish hulless spring barley breeding line, 1N/86, with the chemomutagens N-nitroso-N-methylurea and sodium azide. The mutants were distinguished from the parental line with regard to morphological and yield structure traits. SDS-PAGE of the main hordein fractions, B and C, showed that the electrophoretic patterns of the majority of the analysed mutants were similar to the hordein polypeptide spectrum of the parental line. However, specific hordein patterns were obtained from six of the mutants. In the previous study, the same mutants showed a significantly better feeding value as compared to hulled cultivars and the rest of the analysed mutants.

nutritional value
Opis:: Nutritional value of protein in 146 mutants of hulless spring barley was estimated. Evaluation of protein quality was based on the portion of a relative content of protein fractions with different amino acid composition and, therefore, with different nutritional value. The ratio of albumins, globulins and glutelins to hordein, determining nutritional value of protein in the initial genotype was 1.1; in mutants it was within the range of 0.9-1.5. Several mutants with a high protein content and good nutritional value have been distinguished.

Tytuł:: Intermedium mutants in barley [Hordeum vulgare L.] - diversity, interactions and plant breeding value

Opis:: Mutation research has given an insight into the rather complex genetics of kernel rows in barley. At least 12 gene loci can act to promote the spike development, fertility, and kernel development. Mutants with such effects as sixrow and intermedium phenotypes show clear morphological distinctions among different loci, but also among different allelic mutants. These genes, without exception, are capable of unexpected synergistic reinforcing or disturbing intraction, the extremes being typically six-rowed or deformed spikes, respectively. The investigations have centered on 69 intermedium mutants, representing 9 loci, in double mutant combinations, in double combinations with the six-row gene hex-v, in triple combinations with hex-v, and in triple and quadruple mutant combinations. The effects of the interaction may differ among the three characters of lateral floret development, among intermedium loci, and among alleles of the particular locus. Particular types of gene interaction are indicated, particular loci being more competent than others, and the particular alleles being more competent in relation to the constellation of loci. Accumulation of intermedium genes in more complex gene systems leads to progressive promotion of lateral floret development, but there are indications that such systems may be more sensitive to environmental stress, leading to irregular or even deformed spike formation. Probably, representatives of the hex-v locus should form the fundamental constituent in the synthesis of gene systems with the most efficient promotion of lateral floret development in the breeding of six-row barley.

Opis:: To saturate barley (Hordeum vulgare L.) genetic maps the linkage relationships of two isoenzyme loci Amp2 (aminopeptydase) and Aat2 (aspartate aminotransferase) with known genetic markers were investigated. Results of the genetic analysis support previous information on the localization of these loci on chromosome 1 and 6, respectively. The following recombination values were estimated: between locus Amp2 and T1-3b translocation break point 13.8 ± 2.1%, between locus Aat2 and translocation T6-7i, 17 ± 3.0% and between locus Aat2 and marker о 24.1 ± 3.0%.

Opis:: Induced mutation rate of barley esterase loci has been estimated. Results suggested that about 3% of investigated M₁ spikes had seeds which gave rise to M₂ seedlings mutated in one of four esterase loci. M₁ plants were obtained after chemical treatment of seeds from two spring barley cultivars Aramir and Bielik. The majority of mutants were reconfirmed in the М₃ generation.
