Microsatellite diversity among aerobic and lowland indica rice genotypes with differential water requirements

Published on

Molecular polymorphism in a set of 15 rice genotypes
comprising of aerobic and lowland Basmati, indica and
japonica rice varieties was evaluated using BAD2 aromaspecific and 50 mapped SSR markers. A total of 260 alleles
were detected and number of alleles per locus and
polymorphism information content values ranged from 2
to 9 (average 5.1) and 0.226 to 0.836 (average 0.672),
respectively. Notably, two SSR markers (RM212 and
RM302) amplified specific alleles in all the five aerobic
rice genotypes, which were absent in non-aerobic rice
genotypes. SSR diversity data analyzed using NTSYS-pc
clustering algorithms showed greater divergence between
the Basmati and aerobic rice varieties as compared to
lowland indica and aerobic rice varieties.
