Plant improvement, plant physiology, production and chemical weed control are the major areas of research in the Crop Production department.



So far the TRF has released 29 (vegetatively propagated cultivars) clones. Among these, clones such as UPASI-3, UPASI-8, UPASI-17, UPASI-25, UPASI-27, UPASI-28 and TRF-1 are high yielders. Clones such as UPASI-2, UPASI-6, UPASI-9, UPASI-20 and UPASI-26 and the TRF 3 are moderate yielders but are tolerant to drought. Certain SriLankan clones such as TRI-2024, TRI-2025 and TRI 2026 and a few estate clones such as CR-6017, C-1, ATK-1 and SA-6 are also widely used for planting in southern India. Certain clones such as CR 6017, UPASI 3, TRF 2, are known for their quality. Current clonal selection work in the Anamallais, Nelliampathy and Nilgiris resulted in the selection of 140 bushes based on visual examination. Studies are in progress to monitor their nursery and field performance.





Besides the clones, five biclonal seed stocks have also been released for commercial planting. The biclonal seed stocks are UPASI: BSS-1 to BSS-5. These seed stocks germinate early in the nursery and establish well in the field. They are good for infilling, replanting and extension planting. The stocks are moderate yielders but are tolerant to drought. Seed bari blocks for all the five seed stocks have been established in the Research Institute and in other planting districts for supplying seeds to the tea growers. There are specific designs for seed baries for BSS I and II and III, IV and V. The seed baries are regularly inspected and certified by the personnel from TRF. In the current hybridization programme crosses were made between UPASI -9 and the drought tolerant clone C-1, blister resistant clone SMP-1 and the quality clone CR-6017. Progenies derived out of all these crosses were planted in the field for studying their field performance.




Six compatible graft partners have also been identified by us. The high yielding, drought susceptible clones such as UPASI-3, UPASI-8 and UPASI-17 can be cleft grafted on to the drought tolerant root stock clones UPASI-2, UPASI-6 and UPASI-9.Composite plants developed through grafting are superior to the ungrafted clones in field. When compared to the ungrafted scion clones, the grafts have shown 30% increase in productivity.

To simplify the grafting technique and to make large scale production commercially viable, grafting clips were developed to secure the graft partners at the graft interface. We have also developed motorised scion and root stock maker to facilitate large scale production of grafts. The new scion clones such as UPASI- 28 and TRF 2 and the drought tolerant clones TRI-2025, UPASI-26, C-1 and ATK were evaluated for their graft compatibility. The graft success ranged from 88 to 98 percent in different graft combinations.
