Molecular characterization and identification of candidate markers for seed longevity in soybean [Glycine max (L.) Merill]

Published on Jun 11, 2018 02:54 AM

Soybean [Glycine max (L.) Merill] genotype varies in
storability period during ambient storage. In this study, 33
genotypes of soybean varying in storability (good and
poor) and seed coat colour (black and yellow) were
characterized with 53 SSR and 51 RAPD markers.
Polymorphisms detected by SSR and RAPD markers were
62.26 and 68.62%, respectively. Genotypes with black seed
coat colour showed better storability (89.85%) than the
yellow seed coated genotypes (71.15%) indicating possible
association of black seed coat colour with good storability.
Genetic similarity coefficients obtained through SSR data
analysis grouped the genotypes into two major clusters
representing black and yellow seeded genotypes. SSR
markers Satt371, Satt453 and Satt618 produced specific
allelic bands making them candidate markers for linkage
with seed storability and testa colour. RAPD markers data
grouped the genotypes broadly into two major clusters
that had no congruence with seed longevity and testa
colour.

Keywords: Soybean, seed longevity, candidate marker, SSR, RAPD and testa colour
