Abstract


Molecular marker technology is the genetic tool for assessing genetic diversity and relationships among scented rice and other varieties of rice. In the present study, a random amplified polymorphic DNA technique was used for genetic diversity analysis among 45 genotypes of scented rice with 9 primers. A total of 57 bands were amplified by 9 pre screened polymorphic decamer primers at an average rate of 6.33 bands/primer and 83.17 were polymorphic. The data of 45 genotypes of scented rice were used to generate pair-wise matrix based on Jaccards co-efficient. The similarity co-efficient ranged from 0.423 in between Sugandha-2 and 3231 to maximum of 0.932 in between IR106 and IR-253U. It indicated the closeness of these genotypes. The UPGMA cluster analysis showed similarity between most of the cultivars. The information of the genetic diversity will be useful for the selection of the parents for breeding rice variety
