Abstract: The tree farming is ecologically as well as economically more viable than traditional agriculture. Investment in tree plantations always remained relatively low in India, in spite of the fact that the existing forests cannot continue to meet our wood requirements. However, realizing the existing problem, the expenditure on afforestation has increased enormously from fifth five year plan onwards but still the results on the land are not encouraging and we have not been able to increase area as well as the forest productivity to the desired level. The misery caused to the entire nation due to unprecedented ecodegradation is enormous and warrants immediate remedial measures. To counteract the impending crisis, use of fast growing tree species managed with intensive cultural operations especially in tree farming have opened up new vistas in wood biomass production. Against this backdrop, the current study was planned to screen and identify superior genotypes of Eucalyptus for higher pulp yield. Eleven eucalyptus genotypes were subjected for pulp quality analysis. The clone EC 48 has been characterized for wood quality towards its amenability for pulp and paper industries and the results are very encouraging. The clone expressed the Pulp yield of 48%, Kappa number 19.3 and Lignin content of 23.20% which expressed superiority over the local seed sources. Similarly, this clone expressed acceptable strength properties viz., Burst index (5.0 K Pa m2 g -1), Tear (8.20 m Nm2 g -1 ) and tensile index (80.0 Nm g-1 ) which are again proved superior. Considering the pulp quality, the genotypes EC MTP 48, EC MTP 47 and EC MTP 41 proved superior and this study recommends the suitability of EC MTP 48, EC MTP 47 and EC MTP 41 for pulpwood plantation programme.
