Summary, etc	The increased awareness against deforestation, scarcity of timber from forest and cultivated land, high price of timber etc, have prompted a search for an alternative source for timber. Rubber cultivated over six lakh hectares in India is a potential source to be exploited in this regard. Unfortunately many of the high yielding rubber clones have now timber value. In India about 88;of the total area under rubber is in the small growers sector and the major share of this is planted with clone RRII 105. Though RRII 105 is a prolific yielder, high TPD incidence and the average bole volume are a matter of concern. To identify latex-timber clones, a study has been initiated with five popular clones for Hevea brasiliensis viz, RRII 105, RRII 203, RRII 208, RRIM 600 and GT 1 planted at five agro climatically different locations viz, Chittar (Pathanamthitta Dist), Kulathupuzha (Quilon Dist), Ranny (Pathanamthitta Dist), Balussery(Calicut Dist), and Mundakkayam (Kottayam Dist) within the traditional rubber growing tract in Kerala. The trees on maturity were tapped following 1/2S d/2 system and the yield was recorded for a period of fifteen years. RRII 105 exhibited the highest yield (kg/ha) with location wise variation, followed by RRII 208 and RRII 203. RRII 203 and RRII 208 possessed strainght prominant trunk with high girth increment and the estimation of its bole volume indicated higher values. The incidence of TPD in RRII 203 was lower than that of RRII 105. Even though RRII 203 and RRII 208 are found to be potential latex timber clones in terms of latex yield and timber yield, high incidence of diseases such as shoot rot, abnormal leaf fall, pink and tapping panel dryness makes RRII 208 unfit to be recommended to the growers as a latex timber clone. RRII 203 performed better with regard to yield of latex and timber and low incidence of diseases particularly TPD under 1/2S d/2 system which make it an ideal latex timber clone for Indian small rubber growers.
