Genetic diversity analysis and DNA finger printing are very useful in breeding programs,
seed conservation and management. Jute (Corchorus spp.) is the second most important
natural fiber crop after cotton. DNA fingerprinting studies in jute using SSR markers are
limited. In this study, 58 jute accessions, including two control varieties (Huangma 179 and
Kuanyechangguo) from the official variety registry in China were evaluated with 28 pairs of
SSR primers. A total of 184 polymorphic loci were identified. Each primer detected 3 to 15
polymorphic loci, with an average of 6.6. The 58 jute accessions were DNA-fingerprinted
with 67 SSR markers from the 28 primer pairs. These markers differentiated the 58 jute
accessions from one another, with CoSSR305-120 and CoSSR174-195 differentiating
Huangma 179 and Kuanyechangguo, respectively. NTSYS-pc2.10 software was used to
analyze the genetic diversity in the 58 jute accessions. Their genetic similarity coefficients
ranged from 0.520 to 0.910 with an average of 0.749, indicating relatively great genetic
diversity among them. The 58 jute accessions were divided into four groups with the
coefficient 0.710 used as a value for classification, consistent with their species and
pedigrees. All these results may be useful both for protection of intellectual property rights
of jute accessions and for jute improvement.
