Acacia species trials in MPM have given rise to open pollinated Acacia hybrids from the cross between Acacia auriculiformis and Acacia mangium. They are found to be well adapted to the hot humid conditions of Western Ghats in Karnataka. Acacia hybrids originated from Acacia mangium mother are designated as Mangi-auriculis and those originated from A. auriculiformis as 'Auriculi-mangis'. The growth performance of Mangi-auriculis is closely monitored since 1992 and the wood analysis has indicated that, the wood is suitable for pulp and paper production. Mass production of Acacia hybrid propagules is done through simple and cheap technology and large-scale clonal plantations are established. The MAI of Acacia hybrid in clonal plantation is 32m3 in 5th year whereas the MAI of Acacia auriculiformis is 16m3 at the end of 8 years. It is predicted that Acacia hybrid clonal plantations can achieve a MAI of 40 to 45m3 at the end of 8 years. Clone × site interaction trials are undertaken in both wet and dry zone to choose sitespecific clones for higher productivity. MPM has drawn future strategies in the field of Tree improvement and Tree breeding to further improve the productivity of plantations. The growth potential of Acacia hybrids and their role in plantation programme are discussed in this paper.- Appraisal of Species and Provenances Trial of Tropical Pines in Karnataka

Due to inadequate and diminishing supply of bamboo. the only source oflongfibred wood. Pines with long fibres are invaluable to meet the growing needs ofthe paper industry. Tropical Pines are fast growing with better adaptability and higher productivity. The performance of Tropical Pines varies with species. provenances. climatic and site conditions. Pinus caribaea var. hondurensis. 13 Hand 4 H provenances from Queensland. Australia have been found to be best adapted and potentially most productive seed sources. Pinus oocarpa represented only by one provenance showed satisfactory rate of growth. Pinus kesiya also exhibited satisfactory growth but prevailing climatic conditions slow down/prevent it's further expansion. Prior to large scale investment in industrial plantations with Tropical Pines. it is necessary to lay-out site specific trials to find out their adaptability. suitability and productivity.- Evaluation of the Effect of Pot Size and Time of Sowing on the Production of Pinus caribaea Var. Hondurensis Seedlings
