    Notes: Summary An accession of Avena fatua L. subsp. fatua v. glabrata Peterm. subv. pseudo-basifixa Thell. (A. fatua L. CS Sel. No. 1), collected in Czechoslovakia in 1971, was found to be resistant to a wide range of crown rust races. Analyses of crosses of this oat with cvs. Weikuss, Leanda, Mona, Rodney A, Rodney B, Rodney M, Dodge and K 316 indicated that the resistance of A. fatua CS Sel. No. 1 is conditioned by one recessive gene which is in interaction with one partially dominant gene with additive effect. The expression of rust reaction was affected by temperature. The crown rust resistance genes of A. fatua L. CS Sel. No. 1 were non-allelic with stem rust resistance genes Pg-2 (A) and Pg-4(B).

    Description / Table of Contents: Zusammenfassung Das Weizenmaterial der Sammelreisen in die ČSSR (1974 und 1977) und nach Polen (1976 und 1978) wurde botanisch und im Hinblick auf seinen möglichen züchterischen Wert anhand der Untersuchungen der Originalproben sowie ihres Nachbaus analysiert. Das Material besteht aus Landsortenpopulationen und einigen alten Sorten. Obwohl eine rasche Generosion in den Sammelgebieten zu verzeichnen ist, sind die Populationen sehr variabel und enthalten bis zu 6 Varietäten. Einige der variabelsten Landsorten werden beschrieben. In den Populationen vonTriticum aestivum-Landsorten konnten insgesamt 11 Varietäten gefunden werden; alle mit braunem Korn. Bemerkenswerte Funde sind var.nigroferrugineum aus den gebirgigen Regionen der östlichen Slowakei 1977 und Emmer,Triticum dicoccon, aus südlichen Gebieten der Slowakei 1974. Für züchterische Zwecke besonders aussichtsreiche Merkmale sind kurzer Halm, Winterfestigkeit, Frühreife und Feldresistenz gegenüber einigen Krankheiten. In Gatersleben werden die Landsorten in morphologische Typen aufgetrennt und für künftige Züchtungsaufgaben erhalten.
    Abstract: Краткое содержание Образцы шпенцы, собра нные во время экспеди ции в Чехословакию (1974 и 1977 гг.) и Польшу (1976 и 1978 гг.) ана лизировались как ботанически, так и с точки зрения их ценн ости для селекционны х целей, причëм во внимание принимались как ориг инальные образцы, так и растения, выращенные из собранных семян. Анализированный мат ериал состоит из попу ляций местных сортов и неко торых сортов старой селекц ии. Хотя в местах сборо в и наблюдается интенси вная генная эрозия, популя ции оказались очень и зменчивыми и имеют в своëм составе до 6 разн овидностей. Описываю тся некоторые из наиболе е изменчивых местных с ортов. В популяциях ме стных сортов Triticum aestivum были найдены, в общей с ложности, 11 разновидно стей; все они имели коричневые зëрна. Стоит обратить внимание на var. nigroferrugineum из гор ных областей восточной Словакии в 1977 г. и эммер, Triticum dicoccon, из южных частей Словакии в 1974г. Для селекционных цел ей особенно перспект ивными признаками являются: короткий стебель, зим остойкость, раннезре лость и полевая резистентно сть к некоторым болезням. В Гатерслебене предп олагается расчленит ь местные сорта на отдельные морфологические тип ы и сохранить таковые для будущих селекционных заданий.
    Notes: Summary The wheat material of collecting missions to Czechoslovakia (in 1974 and 1977) and Poland (in 1976 and 1978) has been analyzed botanically and in respect to its possible breeding value by studying the original samples as well as their progenies grown up in the following years. The material represents populations of land-races and some old cultivars. Though there is a rapid genetic erosion in the collecting areas, the populations are very variable containing up to 6 botanical varieties. Some of the most variable land-races are described. In the populations ofTriticum aestivum land-races altogether 11 botanical varieties could be found, all with red grains. Exceptional findings are var.nigroferrugineum from the mountainous parts of Eastern Slovakia in 1977, and emmer wheat,Triticum dicoccon, from southern parts of Slovakia in 1974. The most promising characters for breeding purposes are short straw, winterhardiness, earliness, and field resistance against some diseases. In Gatersleben the land-races are separated into morphologically distinguishable types and maintained for their use in future breeding programmes.

    Description / Table of Contents: Untersuchungen an ABX6-Verbindungen. V. Thermodynamik und Kinetik der Hochdruckumwandlungen von ABX6-Verbindungen (A = Ca, Dy, Ge, Sn, Pb; B = Th, U; X = I)Es wird über Hochdruck-Untersuchungen an ternären Iodiden des Typs ABI6 mit A = Ca, Dy, Ge, Sn, Pb und B = Th, U berichtet. Diese Verbindungen lassen sich umwandeln vom β- in den γ-SnThI6-Typ, beides Varianten bekannter Trihalogenid-Strukturen (BiI3- und PuBr3-Typ). Im Gang der minimalen Umwandlungsdrücke und der Umwandlungsgeschwindigkeiten lassen sich Trends und Besonderheiten aufzeigen, die anhand von geometrischen und elektronischen Faktoren interpretiert werden.
    Notes: The results of high pressure experiments with ternary iodides of the general formula ABI6 with A = Ca, Dy, Ge, Sn, Pb and B = Th, U are described. These compounds transform from a β- to a γ-SnThI6-type structure, both variants of known trihalide structures (BiI3- and PuBr3-type). Trends and pecularities in the values for the minimal transformation pressures and in the velocities of transition are pointed out, and they are discussed in terms of geometric and electronic factors.
