TxD / DxT Hybrid seedlings or other released varieties
This program is also implemented on equal matching share (50:50) between CDB and State Govt. the norms of assistant are Rs. 25 for raising of one seedling. This progamme is beign taken up now only in Departmental Coconut Farms and Nurseries where technical expertise is available. But this can also be taken up in farmers filled where facilities for hybridization and technical expertise are available. The sale rate is decided Horticulture Department, Odisha.
In the production program, the details of male and female parent sources should be clearly recorded. The receipt accrued from the sale of seedling under TxD or DxT scheme shall be intimated to CDB without fail. These receipts are to be shared by the board and state govt. on 50:50 basis.
In the process of DxT seedling production program , dwarf plants are taken as the female parent where in the male flowers are emasculated from the spadix, immediately after its emergence from the plant , leaving the female flowers only and are covered with a cotton cloth. Bag / polythene bag to avoid pollination from any other male parent. Pollens are collected from the tall male parent from the spadix, proceed at 450 F and are brushed (touched) against/ over the stigma of the flowers of the female parent manually. Alternatively this pollination process can also be affected through an auto miser and covered with cotton bag/polythene bag immediately. This process has to be repeated for three consecutive days for effective pollination. The cotton/ polythene bags will be removed from the spadix after week of pollination. The fruits on the spadix will grow and will be matured after 12 months which will be harvested from the mother plant and will be treated as DxT hybrid seed nuts. These seed nuts shall be sown in the nursery beds for raising seedlings and full grown seedlings of 10-12 months old will be obtained for planting in the field. For large scale production of DxT hybrid seedling sufficient number of dwarf plants should be available in the State Govt. farms.
Similar in the case for the production of TxD hybrid seedlings where tall plants will be treated as female parent and dwarf plants will be treated as male parent.
