Abstract :
Seven Brassica napus genotypes were field tested to find out adaptability and productivity of those genotypes in dry land environment of north east of Bali.  The aim of this research is to identify potentially high oil yielding and agronomically stable Brassica genotypes as a new source of biodiesel in Indonesia.  Crop evaluation includes germination rate, plant vigour, flowering time, harvesting time, seed yield and oil content.  Oil extraction technique using ’cold pressing’ technique were trialed.  DNA analysis has been conducted to determine genetic distant between cultivars tested.  Results shows that all cultivars has good adaptability in the tropical areas and more specifically in dry land areas, therefore can be an alternative for biodiesel sources in Indonesia.  All genotypes able to complete their life cycles and produce seeds.  Variation occurs in terms of flowering time.  Some genotypes has an early flowering types while others has intermediate or late flowering.  Pod set was excellence, however, seed set was quite low due to pest attack, namely Diamondback moth.  Oil content of the seeds ranging from 3 – 13 %.  RAPD analyses confirmed that there are variation in their genetic make up, and therefore will be a good source for breeding purpose.
