• Seed play an important role
in any technology.
• No one stop database
available.

3. Review on Other Databases
TNAU Genomics – http://www.tnaugenomics.com/seedportal
• With a view to
provide a user
friendly interface
for users, TNAU
Seed Portal has
been developed.
• With a view to
provide varietal
search for paddy.
• Lacks user

4. Varietal Identification
TNAU Genomics – http://www.tnaugenomics.com/seedportal
• There are many varieties of crop available.
• Market forces are increasingly demanding
pure (or single) varieties of grains for
specific purposes.
• This means varietal testing must become a
standard practice in order to guarantee
the sale of grain.

5. Marker Fingerprint Identification

influence of environment

be updated

12. Future Development
• TNAU Seed Portal is an is an organized database that provides the
information about all crops seed standards, Varietal characters, DUS
characters seed production, processing, testing techniques and
seed legislations.
• Since, SSR Marker Fingerprinting data enables the researchers to
classify the various types of cultivars in a efficient way. It can lead to
seed purity.
• Due to recent developments in IT, steps has been taken to make the
database available to the users in the form of Android application
so that data can be accessed using mobile phones.
• The dynamic nature of the PHP enables us for the further updates
in marker data.
• More SSR markers for each chromosome of paddy will be added in
the days to come.
