In 2005, we discovered some plants of a zucchini yellow mosaic virus (ZYMV)-tolerant oilpumpkin breeding line (Cucurbita pepo), severely affected by a virus. Our first assumption was that ZYMV might have overcome the resistance, but ELISA tests revealed that most likely cucumber mosaic virus (CMV) caused the symptoms, although ZYMV was detected in very low […]

Proceedings of the 1st International Oil Pumpkin Conference
Cucurbit Genetics Cooperative Report 23:86-86 (article 29) 2000 9-13 August 1999 Styria & Lower Austria Preface Extracting oil from pumpkin seed is a century-old tradition centered in Styria, in the south-eastern part of Austria. Some 130 years ago, a recessive mutation occurred which prevented the coat of the pumpkin seed from lignifying. Generations of people […]
Genetic Diversity Within and Between the Species Cucurbita pepo, C. moschata and C. maxima as Revealed by RAPD Markers
Cucurbit Genetics Cooperative Report 23:73-77 (article 25) 2000 Miroslav Baranek, Gergtud Stift, Johann Vollmann and Tamas Lelley Department of Plant Biotechnology, Institute of Agrobiotechnology Tulln, A-3400 Tulln, Austria: [email protected] Introduction. Genes not available in a species can often be obtained through interspecific hybridization. A good example is resistance against Zucchini Yellow Mosaic Virus (ZYMV), which […]
Genetic Diversity in Pumpkins (Cucurbita pepo L.) as Revealed in Inbred Lines Using RAPD Markers
Cucurbit Genetics Cooperative Report 21:48-50 (article 17) 1998 Maria Stachel, Gyula Csanadi, Johann Vollmann and Tamas Lelley Department of Plant Biotechnology, Institute of Agrobiotechnology Tulln, Konrad Lorenz Str. 20, A-3430 Tulln, Austria Introduction. Pumpkin is grown in austria on approximately 8000 ha. The specific hull-less form cucurbita pepo var. styriaca (2n=2x=40) has facilitated easy seed-oil […]
