    Heterosis without selectional coadaptation inDrosophila ananassae (1985)
    Springer
    Theoretical and applied genetics 69 (1985), S. 437-441 
    Details
    ISSN: 1432-2242
    Keywords: Inversion karyotypes ; Relative fitness ; Heterosis in interpopulation crosses ; Coadaptation ; Drosophila ananassae
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary The relative viabilities of homozygous and heterozygous karyotypes were measured by making crosses between strains ofD. ananassae homozygous for ST or inverted gene orders in the second and third chromosomes. The strains utilized during the present study originated from widely separated localities in India, Kuala Lumpur and Kota Kinabaru, Malaysia and Chian Mai, Thailand. The presence of heterosis in many interpopulation crosses is evident from the results which show that the inversion heterozygotes formed by chromosomes coming from distant populations exhibit heterosis. On the other hand, heterosis is absent in two intrapopulation crosses. Thus the present results provide evidence that heterozygosis for many genes and gene complexes does produce high fitness without previous selectional coadaptation.

    Genetics of disease resistance in urdbean (Vigna mungo (L.) Hepper) to the leaf spots caused by Colletotrichum truncatum (Schw.) Andrus & Moore (1988)
    Springer
    Euphytica 37 (1988), S. 279-281 
    Details
    ISSN: 1573-5060
    Keywords: Vigna mungo ; urdbean ; Colletotrichum truncatum ; leaf spotting ; inheritance of resistance ; non-allelic

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary The resistance sources among various test cultivars of urdbean to Colletotrichum truncatum, a leaf spotting pathogen, were identified and genetics of resistance was worked out by studying F1, F2 and F3 generations of crosses between resistant cultivars and the susceptible cv. Kulu 4 and of those among the resistant parents. The resistance was found to be controlled by single dominant genes and the resistance genes were non-allelic.

    Interspecific hybridization between urdbean (Vigna mungo (L.) Hepper) and adzukibean (Vigna angularis (Willd.) Ohwi and Ohashi) (1988)
    Springer
    Euphytica 39 (1988), S. 53-57 
    Details
    ISSN: 1573-5060
    Keywords: Vigna mungo ; urdbean ; Vigna angularis ; adzukibean ; interspecific hybridization ; immuno ; suppressants

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary To introduce resistance to fungal and viral diseases into urdbean (Vigna mungo), it was crossed with adzukibean (Vigna angularis) to achieve an interspecific hybrid between the two species by using different non-conventional breeding methods. Partial success was obtained with the use of UV irradiated pollen, intraspecific hybrids as parents and spray of immuno-suppressants on the female parent under glass house conditions and to the extent of callusing in aseptic culture.

    214Po: A γ-γ and γγ(θ) Coincidence study (1989)

    Notes: Abstract Extensive γ-γ coincidence measurements have been made on γ rays accompanying theβ − decay of214Bi using a conventional GeGe coincidence spectrometer. A total of 33 new γ transitions among levels of214Po have been established. Twenty-three previously reported but unplaced transitions have now been assigned in the level scheme. In addition to confirming 56 previously proposed levels, four new levels are established at 1015.05, 1712.98, 3003.5 and 3160.5 keV. Directional correlation measurements have been made on six weak cascades which have the first excited state in common. Mixing ratios have been deduced for the transitions concerned.

    Thermal stress analysis of underground openings (1989)
    New York, NY [u.a.] : Wiley-Blackwell
    International Journal for Numerical and Analytical Methods in Geomechanics 13 (1989), S. 411-425

    Notes: In the use of underground space for storage of solar energy, storage of excess heat from thermal power plants and containment of nuclear waste, the host medium is subjected to a thermal field accompanied by a thermal stress field. These stresses may endanger the stability and integrity of the structure. In this paper, the stress field, in circular and spherical openings, due to a given thermal field is analytically determined and numerically verified. Both lined and unlined openings are considered. The numerical and analytical results are in a satisfactory agreement. The lining stresses, support pressure and radial interface displacement depend only on the thermal field in the lining. A simplified method of stress computation applicable to a thin lining is also presented.
