    Notes: Summary 1. Gibberellic acid caused a considerable decrease of fertility and some other morphological anomalies in barley plants. The present investigations were carried out to prove whether there is a special sensitive phase for these reactions in plant development. 2. By time-gradual application (spraying daily with GA3, 100 ppm) we observed in all varieties tested — Haisa, mutant MS 1196, mutant MS 733 —a sensitive period around the 30th day after beginning the experiments (two-leaves stage). None of the other application variants showed similar effects (Figs. 1–7). 3. Cytological investigations have proved that GA has no influence on chromosomes and meiosis. There is, however, a marked effect on pollen formation when application is carried out during the sensitive period (Figs. 8–11). Several degrees of pollen degeneration were found which lead to sterility. Femal gametes seem not to be affected. 4. It is discussed whether the characters mentioned above are directly or indirectly effected by GA and whether GA can be used as a possible gametocide in barley breeding. Some remarks are given on the problems which are concerned with the species or varietal specificity of the sterility effect caused by GA.

    Notes: Summary The genetic behaviour of some X-ray induced early heading mutants of both spring and winter barley was studied. In crosses with original varieties all mutants showed monogenic segregation ratios in F2-generations. The early heading date of four mutants was found to be due to a dominant allele, while six mutants are dependent on recessive alleles. In crosses of some mutants one with another four different loci for early heading were identified. For them the genetic symbolmat (matura) resp.Mat is proposed. The combination-effect of two non-allelic genes is always additive and manifests itself in a marked transgression. Plants with such genotypes seem to be useless for breeding purposes.

    Untersuchungen über die Häufigkeit und Weitergabe aneuploider Typen bei autotetraploider Gerste (1966)

    Description / Table of Contents: Zusammenfassung 1. An einem etwa 25 Jahre lang bearbeiteten, im Jahre 1938 von Freisleben durch Hitzeschock induzierten tetraploiden Gerstenmaterial wurden Untersuchungen über das Ausmaß, die Variabilität und die Weitergabe von aneuploiden Typen durchgeführt. 2. Die Aneuploidenfrequenz variierte in drei Versuchsjahren nur geringfügig und hatte bei unserem relativ alten Zuchtmaterial mit etwa 40–45% das gleiche Ausmaß, welches auch für jüngere Generationen anderer Herkunft festgestellt worden ist. 3. Zwischen der Einzelährenfertilität und der Aneuploidenhäufigkeit in der Nachkommenschaft besteht keine Korrelation. Die interindividuelle Variabilität der Aneuploidenfrequenz (ermittelt an 54 Ährennachkommenschaften) reichte von 6 bis 73%. 4. Nachkommenschaftsprüfungen an 28chromosomigen Pflanzen aus Ausgangsähren mit unterschiedlich hoher Aneuploidenhäufigkeit zeigten bisher keinen spezifischen Übertragungsmodus, so daß die Selektion erfolglos blieb. 5. Die Möglichkeiten zur Verringerung des Anteils der sich negativ auf den Ertrag auswirkenden aneuploiden Pflanzen durch Siebfraktionierung der Saatware oder über eine cytologische Selektion auf geringe Aneuploidenfrequenz werden diskutiert.
    Notes: Summary 1. Incidence, variability and transmission of aneuploidy were investigated. The material used was the 25th generation of barley in which Freisleben, in 1938, had induced tetraploidy by Randolph's method. 2. There was only little variability in the frequency of aneuploids over a period of three years. Our relatively old material showed about the same amount of aberration (40–45%) as was found by other workers in younger 4 x-barley generations. 3. No correlation was observed between ear fertility and frequency of aneuploidy in the progeny. The known tendency of increasing aneuploidy with decreasing kernel weight was confirmed by our results (table 5). The interindividual variability of aneuploidy frequency (measured on 54 spike descendants) ranged from 6 to 73% (table 2). 4. Progeny tests on euploid plants derived from spikes with different aneuploidy frequencies showed no specific mode of transmission (table 3), and efforts to select have remained unsuccessful. 5. The high percentage of aneuploid seeds is, in our opinion, responsible for the low productivity of tetraploid barley. The discussion is concerned with problems regarding the reduction of these types by screening out small seeds or by means of cytological selection for low aneuploidy frequency.

Linien der Weizenkollektion der Gaterslebener Genbank wurden unter Verwendung eines modifizierten Testverfahrens auf das Vorhandensein bzw. Fehlen von Gibberellinsäureinsensitivitätsgenen (Gai-Gene) geprüft. Dabei zeigte sich, daß 77 hexaploide und 5 tetraploide Weizen gegenüber GA3 insensitiv waren.
