    Notes: Summary Sixty-two 2x families were generated by intermating 16, 2x clones and evaluated for resistance to potato tuber moth (PTM), Phthorimaea operculella under natural infestation in a storage at San Ramon, Peru and in laboratory tests. The following conclusions could be drawn: (1) relatively simple inheritance was observed for resistance derived from Solanum sparsipilum (spl), (2) the high level of resistance of the original spl has been transferred, undiminished, into an advanced 2x population, (3) simple phenotypic selection was successfully applied to transfer resistance into an improved 2x population, (4) there was a strong indication of reciprocal effects, however spl cytoplasm is not essential for the expression of nuclear resistance genes, (5) antibiosis and antixenosis are the mechanism of PTM resistance in this population, and (6) 4x × 2x crosses could be used to transfer the resistance into commercial cultivars.

    The breeding potential of wild potato species resistant to the potato tuber moth, Phthorimaea operculella (Zeller) (1988)

    Notes: Summary The potato tuber moth, Phthorimaea operculella (Zeller) is an important pest of potatoes in the field and in stores in warm environments throughout the world. In this study genetic resistance to potato tuber moth was identified in clones of Solanum sparsipilum (coded MBN) originally developed for resistance to bacterial wilt and root-knot nematode. Resistance to this pest in S. sucrense and S. tarijense as well as S. sparsipilum was exploited in wide crosses with diploid and tetraploid cultivated potatoes, and haploids derived from S. tuberosum; hybrid progenies were produced. Crosses between resistant S. pinnatisectum or S. commersonii and cultivated potatoes failed completely, although S. commersonii did hybridise with two bridging species S. lignicaule and S. capsicibaccatum which are slightly compatible with cultivated potatoes. Resistance to potato tuber moth was transferred to all progenies except those in which S. tarijense was the resistant parent. The development of potatoes resistant to potato tuber moth is discussed in the context of population breeding for the lowland tropics.

    Ballistic Modification of Composite Modified Double-Base Propellants containing ammonium perchlorate (1987)
    Weinheim : Wiley-Blackwell
    Propellants, Explosives, Pyrotechnics 12 (1987), S. 13-16 
    Details
    ISSN: 0721-3115
    Keywords: Chemistry ; Polymer and Materials Science

    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: The effect of certain lead and copper salts of organic acids and metallic oxides was studied on the burning rates and heat of explosion of CMDB propellants containing AP. Among lead and copper salts, basic lead salicylate gave increased burning rates, whereas lead methylene disalicylate and basic copper salicylate did not produce catalytic effect. In the case of metallic oxides, ferric oxide and cobalt oxide gave better catalytic activity than copper and chromium oxides. On crosslinking of nitrocellulose with an isocyanate, catalytic activity of ballistic modifiers was reduced. Burning rates obtained in a rocket motor (2-kg propellant) were higher by about 15%-20% than by strand burner (Crawford Bomb) method.

    Ballistic Modification of RDX-Based CMDB Propellants (1988)
    Weinheim : Wiley-Blackwell

    Notes: The effect of lead and copper salts and certain metallic oxides was studied on the burning rates of RDX-based CMDB propellants in the pressure region 35-105 [kg/cm2]. Lead methylene disalicylate (LMDS), basic copper salicylate (BCS). cobaltic oxide and lead stannate produced higher burning rates by 10%-16%. However, these additives were comparatively more effective with nitramine-based CMDB propellants than AP-based CMDB propellants. Fluorides of iron, lead and chromium were ineffective as burning rate catalysts. Inclusion of carbon black along with lead salts or metallic oxide gave only marginally higher burning rates. None of the ballistic modifiers studied produced plateau/mesa effect.
