Varieties Released

a)     Simaruba  - Paradise tree

Simarouba glauca is commonly called as 'The King of Oilseed Trees' .The kernels, which form 92 per cent of the seeds, yield on decortication 55 to 65 per cent of oil. The oil of Simarouba glauca is suitable for human consumption without hydrogenation or blending with other fats (Bhagmal and Kochhar, 1991).  Boiling the fat from the kernels and mixing with wood ashes make a crude household soap. The wood of the aceituno tree is white and soft and can be used for making cheap light furniture, boxes, match sticks, yokes for oxen and also as good fuel. Eight-year-old tree yields 42.9% of screened pulp and strength property is comparable with Eucalyptus hybrid (Anonymous, 2005). It has anti-malarial and anti-dysentric properties also (Rath, 1987). Bark and leaves also possess similar medicinal properties. The press cake contains 7.7 per cent Nitrogen (N), 1.07 per cent Phosphorus (P) and 1.24 per cent Potassium (K) and is valuable as organic manure. The species is highly drought tolerant, adapts to all kinds of soil except coastal sandy soil, can check erosion and has enormous potential for wasteland reclamation. It is a promising species for wasteland afforestation and establishing green belts.

Considering its ecological and economical significance, the species has been tested under various agro climatic zones of the state since 1995 and based on the appreciable early performance in varied climatic and soil conditions, it has been released (introduced) by Tamil Nadu Agricultural University during January 2000 for cultivation by farmers and other stake holders. As the species is dioecious producing more male trees (60%), cleft grafting technique has been standardized to produce more female trees for commercial plantations. So far, the Institute has supplied more than 300000 seedlings and 25000 grafts to various stake holders.

b)     Casuarina clones

This institute has developed superior clones in Casuarina (MTP CA1 – Casuarina equisetifolia; MTP junghuhniana 1) as a source of short rotation, industrial pulp wood species with a cellulose content of moreC than 45%, kappa number around 20% with an yield of 100 tonnes/ha and 150 tonnes per ha respectively.

  c)     Eucalyptus clones

The institute has developed superior clones in Eucalyptus (FCRI EC 48, FCRI 103, FCRI 53, FCRI 56 and NGL 2) as a source of higher productivity, superior pulp wood quality and also as a clone suitable for bio drainage purpose. These clones are promoted and demonstrated and are at varied stages of adoption.

d)    Development of alternate pulp wood

Two species have been identified viz., Melia dubia and Dalbergia sissoo as an alternate source of pulp wood with a potential of 50% cellulose and around 20% kappa number coupled with suitable fibre strength properties viz., tear strength, burst index and tensile index.  The two species have been transferred to paper industries for further mass multiplication and promotion. Clones of nearly 20,000 numbers have been multiplied and promoted.

 e)   Jatropha hybrids

          Biofuel research formed major activity of the research agenda of this institute. Accordingly the institute has developed 27 hybrid derivates with varying degree of variability in terms of seed and oil yield and associated morphological characters. From these hybrid derivates two distinct hybrids viz., FCRI HC 21 and FCRI HC 32 have been certified as new developed varieties by NBPGR and assigned the new variety number of INGR 09037 and INGR 09036 respectively.
