Seed play an important role in any technology embedding and we have to produce pure, quality, resistant, healthy seeds for production of healthy food to satisfy our needs.The vast variety of information regarding seeds is scattered and no such organized one stop database available at present Hence information regarding quality seed production, maintenance of seed quality and purity, minimum seed standards of the crop, Varietal characters, DUS characters and many are incorporated in the user friendly interface TNAU SEED PORTAL .

4. Varietal Identification
• 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.

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.
