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.

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.

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:: Poor seed set is a limiting factor in alfalfa breeding, as it slows the selection response. One strategy used to overcome this problem is to search for mutations of inflorescence morphology. Long-peduncle (lp), branched-raceme (br) and top-flowering (tf) inflorescence mutations increase the number of flowers per inflorescence, but they do not improve seed set per flower. Here we assessed pollen tube growth in styles of those inflorescence mutants and we observed embryo and endosperm development in seeds 1 to 16 days after pollination (DAP). The number of pollen tubes penetrating the style and the ovary was similar in all tested mutants and in the reference cultivar Radius. At 2 DAP, fertilized ovules were 2.7–3.9 times less numerous in certain inflorescence mutants than in the short-raceme cv. Radius. Ovule degeneration progressed at 2–4 DAP in all analyzed plants. Most ovules were not properly developed in the control cultivar (62%), nor in the forms with mutated inflorescence morphology (69–86%). The number of seeds per pod was lowest in the tf form despite its having the highest number of ovules per ovary. It appears that the number of ovules per pistil is not a crucial factor in seed set in alfalfa when fertilization efficiency is very low. Both poor fertilization and gradual ovule degeneration were factors causing poor seed set in the investigated alfalfa genotypes.

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.

Opis:: Anther and somatic tissue culture in combination with mutagenesis were carried out to evaluate the efficiency of different mutagenic treatments of various in vitro culture materials, and to obtain some promising variants for rice improvement. Results indicated that in japonica rice radiation treatment of dry seeds and young panicles influenced the percentage of green plantlets regeneration from anther culture. Both treatments increased significantly the percentage of regenerated green plantlets in comparison with the control. Irradiation with 30 Gy of rice callus increased also the percentage of regenerated green plantlets. For indica rice, the combination of the suitable dose of gamma rays irradiation on seeds and an improved medium, increased the percentage of callus induction. This approach made it possible to use anther culture in indica rice breeding. Somatic tissue cultures combined with radiation-induced mutagenesis led to the development of a number of promising mutants including some new cytoplasm-nucleus interacting male-sterile lines with almost 100% stigma exsertion. Their development would be of practical significance for increasing the genetic diversity for production of hybrid rice.

Opis:: The aim of the study was to investigate the delayed ripening caused by the nor gene and its possible interaction with selected traits observed in two combinations, namely, Dw₄ x nor and C36 x nor. The lines Dw₄ and C36 differed from each other in the majority of examined characters. There was no significant effect of reciprocal crosses on these characters (total yield, number of fruits, fruit weight, locule number, earliness and fruit shelf life). In Dw₄ x nor fruit weight was inherited with incomplete dominance of small fruit, while in C36 x nor the inheritance proved to be intermediate. This important statement made it possible to distinguish the hybrids characterised by fruit weight intermediate in relation to the parental forms. The experiments attested to the high significance of additive effects for fruit weight, periods from sowing to ripening and from flowering to ripening in both combinations and for locule number in Dw₄ x nor. It was also found that the nor gene slightly delayed the onset of fruit ripening but did not affect such traits as total yield, number and weight of fruits, locule number and period from sowing to flowering. In its homozygous state the nor gene totally inhibited fruit ripening. However, as a heterozygote it revealed an intermediate action, slowing down fruit ripening and prolonging shelf life 2-3 times as compared with standard tomato. The expression of the nor gene was also found to be dependent on the genetic background. Line C36 positively influenced the flavour and firmness of hybrid fruits, while Dw₄ had a negative effect on fruit quality.
