Important

Isozyme variation in seven populations of Santa/urn a/bum L. in Kerala

Published on

Genetic diversity within and between seven sandal
populations viz., Marayoor, Wayanad, Thenmalai,
Wadakkanchery, Ottappalam, Kasargod and Kannavam
were investigated using metabolic enzymes viz., peroxidase
(PRX), shikimate dehydrogenase (SKDH), gluco phosphate
isomerase (GPI), malate dehydrogenase (MDH) and esterase
(EST). Eight out of the eleven resolved loci (72.73%) were
found to be polymorphic at least in one of the individuals
analysed. The average rate of gene flow between the
populations was found to be very ~ow (0.11). An
examination of the partitioning of genetic diversity within
and between populations indicated that 69% of the
observed variation occurred between populations and the
rest of the variation within populations. The genetic
relatedness of the seven populations revealed by the
UPGMA dendrogram, showed genetic grouping of
populations in three clusters. Kasargod and Kannavam
were the most genetically similar and Marayoor and
Wayanad were the most diverse populations.
