Abstract
One of the major applications of molecular techniques to investigate and estimate the level of genetic diversity in germplasm and populations, it is ideal for use in breeding and management of plant genetic resources is maintained. The diversity and genetic relationship of 25 samples of cultivated and wild species of crocus C. sativus, C. speciosus, C. cansellatuse, C. haussknechii and C. michelsonii were studied using several ISSR markers. Eight ISSR primers produced 78 bands it scored. Average polymorphism of ISSR markers obtained 87/3 %. Results of analysis of molecular variance showed that genetic variation between populations and within populations were significant. Based on this analysis with ISSR markers genetic variation among populations was 36%. Values of polymorphism information content (PIC) varying from 0.220 to 0.341. The results showed that there is a lot of variation between and within species crocus that can be used to value the plant breeding programs.
