The German agronomist and vine grower Peter Morio (1887-1960) studied agriculture at the Technical University in Munich. From 1921 to 1948 he was an assessor at the teaching and research institute in Neustadt an der Weinstraße (Palatinate). In 1926 he founded the branch office for vine breeding of the Bavarian State Institute for Viticulture, Fruit Growing and Horticulture in Würzburg at the Geilweilerhof
in Siebeldingen-Pfalz and planted the first seedlings. By 1928, 8,000 vines had already been planted out and the extensive vine breeding of today's institute was founded. In the beginning, his main focus was on clone selection
(e.g. the Riesling clone No. 90) and the breeding
of fungus-resistant varieties between European
and American vines
From 1937 onwards, he focused his activities on the crossing of
European varieties and created, among others, the new varieties Bacchus
. From 1928 to 1934 he was also a viticulture expert for the Oberhaardt area (today Südliche Weinstraße) in Landau (Palatinate). The "Gemeinschaft der Förderer und Freunde des Instituts Geilweilerhof e.V." awards the Peter Morio Prize for special services to vine breeding. It was awarded for the first time in 1993 and since 1994 every two years.
