Abstract
A spontaneous mutation with “naked” (hull-less) seeds (Cucurbita pepo L. convar. pepo var. styriaca Greb.) occurred about 100 years ago in Europe.
This material was used as the basis of the breeding work of pumpkins at Saatzucht Gleisdorf in Austria.
Different germplasm selections have been bred for higher seed yield, better agronomic characters, increased oil content, unsaturated fatty acid content, and tocopherol content.
Under our climatic conditions in Austria it seems that the oil content and the linoleic acid content of the seeds is higher than in regions with higher temperatures.
As for other oil crops, an increase in the percentage of linoleic acid is associated with a decrease in the oleic acid.
Considering the range of variation found in our genetic material, increases in the oil content, linoleic acid content, and tocopherol content through breeding efforts seem likely.
