GUWAHATI, Sept 19 � The 103-year-old Tocklai Tea Research Institute (TTRI), formerly Tocklai Experimental Station of the Tea Research Association (TRA), has developed two tea clones � TTRI-1 and TTRI-2. Both the clones were released for commercial use at the 50th annual general meeting (AGM) of the TRA yesterday at Kolkata.

It needs mention here that the first tea clone � Tocklai Vegetative (TV)-1, developed by Tocklai, was released in 1949 and the last of this series TV-31 was released by it in 2006. TTRI-1 and 2 are the first two tea clones released by the institute after a gap of 8 years from the release of TV-31, TRA secretary Joydeep Phukan told this correspondent today.

Phukan said that the TTRI-1 is draught tolerant and it possesses high yield potential with desired quality for CTC manufacture. The TTRI-2 is meant for orthodox variety of tea and it is expected that after 5 to 6 years, the producers would be able to release their products from TTRI-2 clone to the market.

Rajani Ranjan Rashmi, Additional Secretary, Union Ministry of Commerce, released the tea clones for the tea industry and symbolically handed them over to AK Bhargava, Vice Chairman, Indian Tea Association, Bidyananda Barkakoty, Chairman, North Eastern Tea Association and Raj Barooah, Chairman, Assam Tea Planters� Association at the function, Phukan said.

Phukan further apprised that the TTRI-1 originated from a seedling population selected from Betjan Jat seed nursery of Cinnamara TE and planted at Tocklai in 1980. Over the years under testing, yield of TTRI-1 was about 35 per cent higher than the mean yield of control clones (TV-1, S3A3 and TA-17). It is expected to yield 3500-4000 kilograms (kgs) per hectare. This clone is being recommended after a gap of 8 years after the last release of TV-31.

The TTRI-2 is a selection from an early germplasm collection of seed jats (stock 19) at Tocklai. Over the years under field testing, yield of TTRI-2 was significantly higher than the control clones (TV1, TA17 and S3A3) and is expected to commercially yield more than 3500 kgs made tea per hectare. TTRI-2 has a good potential for 100 per cent orthodox manufacturing. The release of a quality clone is being done after a gap of 38 years from the last release of the quality clone TV-21, Phukan added.
