Opis:: After duplicating the chromosome number by colchicine in sterile F₁ 16-chromosome hybrid T. pratense × T. diffusum some partially fertile plants with 32 chromosomes were found. Male fertility (viability of pollen grain) was from 69.3% to 86.2% (on average 81.8%), whereas female fertility estimated as seed setting after cross- and self-pollination was 21.8% and 6.9%, respectively. Male and female fertility as well as somatic chromosome number were examined in the F₂-F₄ generations. Selection for female fertility resulted in increasing seed setting in the first two generations (F₂ and F₃) and in decreasing it in F₄ generation. An average seed setting in the F₂-F₄ generations after cross-pollination amounted to 22.2%, 43.6% and 12.9%, respectively; after self-pollination it was 25.2%, 27.6% and 1.9%. In the F₂ generation all the plants had 2n=32 chromosomes. In the next generations there appeared aneuploids, among which 30-chromosome individuals were predominant.

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:: Twenty field-grown genotypes of diploid Italian ryegrass (Lolium multiflorum Lam., 2n = 2x = 14) were tested for their ability to induce callus and regenerate plants. Callus cultures were initiated from segments of immature inflorescences cultured on the MS medium supplemented with 4.0 mg L⁻¹ 2,4-D. The calluses were subcultured first on the maintaining medium (MS medium with 2.0 mg L⁻¹ 2,4-D) and later on the rooting medium (MS medium with 0.2 mg L⁻¹ 2,4-D). The frequency of callus induction varied depending on the source of explant and the initial genotype. A total of 473 green plantlets were regenerated, of which 420 were established in the soil. All these plants had the morphological characteristics of Italian ryegrass. Among 372 regenerants analysed cytologically, 302 (81.2%) had the expected diploid chromosome number (2n = 2x= 14), 65 (17.5%) were tetraploid (2n = 4x = 28); several aneuploids and mixoploids were also observed. All diploid and tetraploid regenerants were male and female fertile. However, a great variation of female fertility within and between both groups of regenerants was observed.

Opis:: Plants were regenerated from immature embryo cultures of 35 winter wheat genotypes. General responses of regenerated plants were investigated and a total of 7142 R₂ spike lines from 1593 R₁ plants were assessed in the field for somaclonal variants in 1985/86, 1986/87 and 1987/88. Selected variants were studied for their possible genetic inheritance. From regenerated plantlets, 81% survived and 63% produced fertile plants. Forms with reduced plant height, length of spike and other morphological abnormalities were found in this progeny. Populations of R₁ plants were highly variable due mainly to the physiological disturbances resulting from the in vitro process. Overall somaclonal variation frequencies were 14.2% per plant basis and 5.3% per R₂ spike basis. The variants were similar in the three different R₂ generations with predominant variants being negative in plant height, maturity, awns, spike type and plant type. Both uniform R₂ variant families and spike lines were found in addition to the segregating variants which constituted the majority. On average, in a variant family or line, 18% and 14% of their component lines and plants were variants, respectively. Inheritability was demonstrated for the uniform variant families and spike lines as well as segregated variants. Of those 134 selections, about 70% were classified as inheritable. Both recessive and dominant gene mutations at one, two or three loci were evident in some variants as suggested by the segregating data.

Opis:: Recent advances at Institute of Grassland and Environmental Research (Aberystwyth, U.K.) in cytogenetics of the Lolium/Festuca complex places us in the advantageous position of being able to map genes of agronomic importance onto chromosome arms using fluorescence in situ hybridization (FISH). The ability to physically map genes leads to the capability for "dissecting" quantitative traits into their different components and will lead to better understanding of the complex physiological processes involved and the identification of their genetic control. By tagging genes of interest, using molecular and morphological markers, it will be possible to select and combine suites of desirable genes in a single genotype and thus produce novel cultivars by conventional breeding procedures. Programmes for introgression depend on the relationships between species and on levels of chromosome pairing. Phylogenetic relationships within the Lolium/Festuca complex are being determined using both genomic in situ hybridization (GISH) and FISH. With recent advances in genetic manipulation within the Lolium/Festuca complex, opportunities now arise for gene transfer from Lolium and Festuca species into other important agricultural crops.

Opis:: Single and double-gene Rhtl, Rht2, Rht3, Rht1 + Rht2 and Rht3 + Rht2 isogenic lines of wheat in four parental rht varieties were grown in drilled yield trials at four sites in 1989. The same lines were also grown in 1988 together with hybrid genotypes from CHA (chemical hybridising agent) F₁ production plots. In the inbred lines shorter than one metre, Rht alleles reduced total shoot biomass by shortening the straw; mass of straw per unit plant height was unaffected. Highest grain yield was obtained from plant heights between 70 and 100 cm. The Rht genotype achieving this stature varied according to parent varietal height. The hybrids grown allowed comparisons between intra- and inter-varietal crosses over a range of Rht genotypes. In F₁ hybrids positive heterosis was observed for plant height, grain yield and mean grain weight. Highest yields were obtained from inter-varietal hybrids carrying one, two or three doses of Rht1 or Rht2 or one dose of Rht3. An Rht3lrht hybrid showed resistance to premature α-amylase production during grain ripening.

Opis:: Fusarium wilt is the most harmful soil-borne disease of lupins in Russia and in the Ukraine. The aim of the studies was to find broad resistance to disease in collection accessions and to breed lupin forms resistant to Fusarium wilt for the future breeding program. Lupin cultivars and lines (547 accessions) from the genebank of the N.I. Vavilov All Russian Scientific Research Institute of Plant Industry, St. Petersburg, Russia, were tested for Fusarium resistance under different environmental conditions of three regions in Russia and in the Ukraine on plots with artificially infested soil. So, differences in the disease susceptibility of the same accessions were found in contrasting environments. Resistant forms from one region were crossed with accessions showing their resistance in two other regions to accumulate resistance genes in new genotypes. As a result of hybridization two transgressive forms were obtained in F₄ of the crosses cv. Frost × cv. Apendrilon (L. angustifolius) and line G-413 × line 85 (L. luleus). Their resistance in all three regions appeared to be higher than that of their parental forms. These two lines were found suitable for the breeding programme of Fusarium resistant forms in Russia and in the Ukraine.

Opis:: The results of plant breeding trials with populations of fodder pea strains and broad bean hybrids were the basis of consideration on the interrelationship between some traits - the yield structure elements. Developed by Eaton, a relatively new method of yield component analysis called the two-dimensional partitioning method (TDP) was applied to analyse the data. The method, which combines multiple regression and ANOVA, allows for concise tabular presentation and simple interpretation of the distribution of traits in one direction and the sources of variance according to ANOVA model in the other direction. Additionally, the interpretation of the results was supported by such standard statistical techniques as ANOVA, simple and multiple regression and path analysis. The main components of pea yielding were plant height and the number of pods per plant. Among the analysed characters of broad bean the number of nodes with pods on the main stem, which turned out to be the determinant of broad bean yielding, might be strongly affected by environmental conditions. The number of nodes with pods might be considered a selecting character of high potential yielding of broad bean genotypes.
