ABSTRACT
During European domestication, people selected oil pumpkins containing seeds rich in oil. Pumpkins develop medium deep taproot, and their roots have weak suction abilities. Oil pumpkins are extremely susceptible to the cucumber mosaic virus. After World War II, Austria, Belgium, the Netherlands, North America, and Russia began planned production of camelina as oilseed. Camelina is proposed as an appropriate cover crop in systems where soil is cultivated without the use of a plow, and it is suitable for natural agriculture due to its weed competitiveness. Soils with good drainage are important in a humid climate, but in dry areas irrigation is essential although safflower is known as a crop that is drought resistant and appropriate for semiarid condition. The genotypes that contain highly concentrated opiate alkaloids are used for this kind of production, and they are grown in hot areas, mostly tropical climates. The seeds and oil, organically produced in some places, are an important product in gastronomy.
