One possible method for the determination of DNA-polymorphism is the PCR-based AFLP (Amplified Fragment Length Polymorphism). This method had been succesfully introduced to the Department of Botany at University of Debrecen in 2000-2001 with the examination of hay saffron (Crocus sativus L.) and its allies. Hay saffron is grown as a spice for s
...ome thousand years producing the most expensive spice in the world. This plant is sterile, triploid reproduces only vegetatively with no fertile seeds. However its origin is unknown it exists only in cultivation and it is a mutated variety of another species or an artificial or natural hybrid. Usual methods for the systematic examination are restricted hence it seemed to be reasonable to apply molecular biological methods in its case. Results of this work include the introduction and many fold application of the method beside ensuring the consequences of science literature with determining the C. cartwrightianus to give the most similar genetical pattern to C. sativus.
The hay saffron (Crocus sativus L.) is a sterile triploid plant, known in human culture only, with no fertile seeds produced. The origin of saffron is still a mist, however it is assumed to be an autopoliploid mutant or a hybrid. The recent classification and most of the former taxonomic publications define C. sativus to be derived from C. cart
...wrightianus, a wild species. Because of the sterility of hay saffron it seemed to be reasonable to apply molecular biological methods to complete classical taxonomic studies in examining its relations. The DNA polymorphism based AFLP method has confirmed the close relationship between these species.
