(1) Development of New Strains:
- The new strains are developed by ICAR Crop Research Institutes and State Agricultural Universities for specific purposes. Various breeding methods are used for development of new strains in self- and cross-pollinated species.
(2) Evaluation of Performance:
- The performance of newly developed strains is evaluated in AICCIP. ICAR Institutes, SAUs and private registered seed companies enter their improved strains/hybrids in the AICCIP of respective crop for multi-location testing. The new strains are tested at multi-locations under the coordinated project for a minimum period of three years/ seasons.
- The new variety is first tested for yield under the initial varietal trials (IVT); the promising ones are promoted to the advanced varietal trials (AVT) in the second year. The strains that give good performance in AVT for two years are selected.
(3) Identification of Superior Strains:
- The strains which show good yield performance in AVT are identified as superior strains and are considered for release in the workshop meetings. The newer agro and plant protection techniques required to obtain potential yield of new strains are also worked out by that time. The workshop after considering the new promising varieties, recommend them to replace existing varieties.
(4) Release and Notification:
- The proposal for release of new varieties is put up in a prescribed proforma to variety release committee. There are two types of variety release committees, viz. State Variety Release Committee (SVRC) and Central Variety Release Committee (CVRC). In case of state variety release committee, Director of Agriculture for field crops and Director of horticulture for vegetable and horticulture crops is the chairman.
- In central variety release committee, Deputy Director General (Crop Science) of ICAR is the Chairman. The release proposal of varieties recommended for All India release is put up before CVRC, while for those recommended for release in a particular state is placed before the SVRC of respective state.
- These committees consist of scientists, and representatives of seed producing organizations (NSC, SSC and SSCA) and other related government agencies. After release, the variety is notified. Seed production can be taken up only after notification of new varieties.
