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 (Germany) and planted the first seedlings. By 1928, 8,000 vines had already been planted out and the extensive vine breeding activities of today's institute were established. At the beginning of his work, his main focus was on clone selection, such as the very successful Riesling clone No. 90, and the breeding of fungus-resistant varieties between European and American vines. From 1937 onwards, he then focused his activities on crossbreeding between European varieties and created, among others, the new varieties Bacchus, Domina, Forta, Madeleine Sylvaner (2), Morio-Muscat, Noblessa and Optima. Between 1928 and 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.
