    Notes: Summary A somatic hybridisation programme was undertaken to evaluate the expression of reducing sugar accumulation in potato. Interspecific hybrids created between the Solanum tuberosum cultivar Record and the diploid species Solanum phureja were evaluated at the morphological and molecular levels. These analyses indicated that the protoplast regenerants were partial (asymmetric) hybrids which had undergone elimination of S. phureja chromosomes. Tubers of the parents exhibited significant differences for reducing sugar accumulation during cold storage with S. phureja having lower levels of glucose and fructose than Record. The somatic hybrids resembled the S. phureja parent in terms of reducing sugar accumulation demonstrating that low reducing sugar accumulation is dominant to high reducing sugar accumulation in these particular genotypes. These results are discussed in relation to the exploitation of asymmetric hybridisation for the production of potato genotypes for the potato processing industry.

    Description / Table of Contents: On étudie les informations relatives aux indices de réfraction pour quelques gaz pour obtenir des formules analytiques. De celles-ci on obtient le coéfficient du terme principal de l'interaction de longue portée entre deux corps ainsi que celui de l'interaction de longue portée non-additive entre trois corps. On calcule les coéfficients correspondants pour des mélanges des gases He, Ne, A, Kr, Ze, H2, N2 et CH4, l'erreur probable étant 5%.
    Abstract: Gewisse Brechungsindexinformationen für mehrere Gase sind zu analytischen Formeln angepasst. Von diesen berechnet man die Koeffiziente des Prinzipalglieds der Wechselwirkung zwei entfernter Körper und der non-additiven Wechselwirkung drei entfernter Körper. Koeffizienten sind für Mischungen der Gase He, Ne, A, Kr, Xe, H2, N2 und CH4 berechnet, mit einem wahrscheinlichen Fehler von 5%.
    Notes: The refractive index data for various gases are fitted to analytical formulae from which may be calculated the coefficient of the leading term of the long-range two-body interactions and the coefficient of the leading term of the long-range non-additive three-body interactions. Coefficients are obtained for mixtures of the gases He, Ne, A, Kr, Xe, H2, N2 and CH4, the probable error being 5%.
