Genetic diversity analysis of traditional Sali rice {Oryza sativa L.) germplasm of Assam through RAPD markers

Published on

Genetic diversity of Assam rice collection was analyzed
using 51 Sali rice accessions were characterized based
on 72 random amplified polymorphic DNA (RAPO) markers.
Among the 11 primers, the percentage of polymorphic
bands ranged from 33% (OPK-14) to 100% (OPK-19),
showing a high degree of molecular variation. The
Jaccard's similarity co-efficient used for RAPO data was
found to be 0.515, indicating a high level of diversity.
Cluster analysis of RAPO data using the UPGMA revealed
11 pairs of accessions might be considered as suspected
duplicates. The potentiality of using molecuiar marker in
rice germplasm management of Assam rice collection is
discussed.
