Varietal release

Before a variety is released and reaches to the farmer, the All India Co-ordinated Crop Improvement Project identifies the variety for release in its workshop as per the established norms for testing for its value for cultivation.
Presently, All India Co-ordinated Crop Improvement (AICCPs) Projects have been created for almost for all the crops or groups of crops (Paroda, 1992).
AICCIPs follow a three tier system of multilocation evaluation spread over a minimum of three years involving the following stages:

• First year - (IET, Initial evaluation trial)
• Second year — Advance varietal trial — I (AVT - 1)
• Third year — Advance varietal trial — II (AVT-II)
