    Notes: The N- and C-banding patterns of the chromosomes of the hexaploid wheat cultivar ‘Viking’, and the hairy-necked line derived from it, were described. Except for chromosome 4B (formerly 4A), no significant variation in banding patterns were found between the two genotypes. In addition to a 5BS.7BS (5BL.7BL) translocation in both genotypes, the presence of a small 5RL rye segment in a terminal position on the long arm of chromosome 4B was suggested by banding and confirmed by meiotic analysis, and by the hairy neck marker as well as by rye-specific leaf esterase bands in the translocation line. The translocation breakpoint is presumed to be located in the distal 4BL2.2 and/or 5RL2.3 band. The hairy-necked ‘Viking’ was shown to be copper efficient. Its utilization in wheat breeding programmes is proposed.

    RFLP mapping of genes affecting plant height and growth habit in rye (1993)

    Notes: Summary RFLP mapping of chromosome 5R in the F3 generation of a rye (Secale cereale L.) cross segregating for gibberellic acid (GA3)-insensitive dwarfness (Ct2/ct2) and spring growth habit (Sp1/sp1) identified RFLP loci close to each of these agronomically important genes. The level of RFLP in the segregating population was high, and thus allowed more than half of the RFLP loci to be mapped, despite partial homozygosity in the parental F2 plant. Eight further loci were mapped in an unrelated F2 rye population, and a further two were placed by inference from equivalent genetic maps of related wheat chromosomes, allowing a consensus map of rye chromosome 5R, consisting of 29 points and spanning 129 cM, to be constructed. The location of the ct2 dwarfing gene was shown to be separated from the segment of the primitive 4RL translocated to 5RL, and thus the gene is probably genetically unrelated to the major GA-insensitive Rht genes of wheat located on chromosome arms 4BS and 4DS. The map position of Sp1 is consistent both with those of wheat Vrn1 and Vrn3, present on chromosome arms 5AL and 5DL, respectively, and with barley Sh2 which is distally located on chromosome arm 7L (= 5HL).

    Notes: Abstract A 4B/5R wheat-rye translocation line derived from the Danish wheat variety ‘Viking’ was revealed to be highly copper efficient. The chromosomal exchange includes a very small terminal segment of chromosome arm 5RL of rye which was physically mapped by genomic DNA: DNA in situ hybridization and chromosome analysis. The gene for Cu efficiency (Ce) is linked to a dominant hairy neck character from rye (Ha1) and to two rye-specific leaf esterase loci (Est6, Est7), all of which are postulated to map to the distal part of 5RL. Genes coding for mugineic acid synthetase and 3-hydroxymugineic acid synthetase also on chromosome 5R are not included in the 4B/5R translocation and hence map outside the terminal 5R region. These genetic and molecular markers can be useful tools for large-scale screening in wheat breeding programmes.

    Description / Table of Contents: At the technological performance of the microsuspension polymerization of vinyl chloride a constant velocity of polymerization over the whole course of reaction is desired. This will be achieved by the use of a redox system consisting of dilauroylperoxide, dicetylperoxidicarbonate, copper sulfate, and ascorbic acid.
    Notes: Bei der technischen Durchführung der Mikrosuspensionspolymerisation des Vinylchlorids wird eine konstante Bruttopolymerisationsgeschwindigkeit während des ganzen Reaktionsverlaufes angestrebt. Dies wird durch Verwendung eines Redoxsystems aus Dilauroylperoxid/Dicetylperoxidicarbonat, Cupfersulfat und Ascorbinsäure als Initiator erreicht.
