    Notes: Ten natural populations of caper spurge (Euphoria lathyris L.) were evaluated in two greenhouse experiments. It appeared that the ‘between population’ component of variance predominated for most characters. Heritability values Fit into the general picture of seed oil-containing wild species. From estimates of response to selection it is concluded that for developing caper its genetic- base has to be broadened.

    Notes: The interrelationships of seed yield components in Euphorbia lathyris L. have been studied by means of path-coefficient analysis. Two of seven components, ‘Number of flowers of primary inflorescence’ and ‘Number of flowers of secondary inflorescences’ proved to be of major importance through direct effects on ‘Total number of fruits’ as indicator of seed yield. Indirect effects generally arc being canalized via the same variables. Selection for seed yield is made possible through the relation between ‘Number of secondary branches’ and ‘Number of flowers of secondary inflorescences’.

    Description / Table of Contents: Zusammenfassung In drei mehrjährigen Serien mit Erdbeerklonen (Fragaria ananassa Duch.) wurden die Erblichkeit im weiteren Sinne und der voraussichtliche Selektionsgewinn sowie die Wiederholbarkeit für zwei Tiefgefriermerkmale, die Saftabgabe nach dem Auftauen und die Formbeständigkeit der Beeren, geschätzt. Es zeigte sich, daß in allen Fällen noch nach 12–15 Jahren Züchtung und Selektion eine große genetische Varianz verfügbar war. Eine Berechnung der Ökovalenz der beiden Merkmale ergab, daß eine Tendenz zu größeren Ökovalenz-Werten in Abhängigkeit von der genetischen Divergenz besteht.
    Notes: Summary Heritability in the broad sense, the expected genetic advance with selection and the repeatabilities for two freezing characteristics were estimated in strawberry clones (Fragaria ananassa Duch.) over several years. The freezing characteristics were extravasation of juice and texture of berries after thawing. It could be shown that after 12–15 years of breeding and selection there was still much genetic variance. An estimation of ecovalence for these characteristics showed that ecovalence depends on genetic diversity.
