Abstract

Shorea roxburghii or white meranti belongs in the family Dipterocarpaceae. It is native to the northern part of Peninsular Malaysia, Thailand, Myanmar, India and Indo-China. This species has been a focus of interest in forest tree breeding and plantation in Malaysia due to its robust characteristics such as high survival rate, adaptability to grow in disturbed areas and considerably fast growth. Since 2018, progeny trial plots have been established utilizing 27 half-sib families at three FRIM’s research stations (SPF); SPF Jeli (Kelantan), SPF Mata Ayer (Perlis) and SPF Setiu (Terengganu). A progeny trial is conducted to identify the genetic characteristics of the parent trees. The outcome of the trial will be selected progenies that would become the sources of high-quality planting materials. The progeny trial plots could also be converted into Seedlings Seeds Orchards (SSO). SSO serve as seed production areas for high-quality planting materials and also as germplasms in an effort toward genetic conservation. This paper will be discussing the findings on the growth variations within and among the 27 half-sib families grown in the progeny trials at three different sites at the age of three years old. The sites were selected based on different geographical conditions, environments and soil properties. SPF Mata Ayer has sandy loam type of soil, extremely hot weather conditions and most importantly S. roxburghii is native to this area. Second, SPF Jeli on the other hand located in hilly areas that have silty clay loam type of soil and higher annual rainfall. Third, the main reason for choosing SPF Setiu is to experiment with the Beach Ridges Interspersed with Swales (BRIS) type of soil. Assessment of the height (HT) parameter at three years old showed that there were high variations among the Sites, Family and Site by Family interactions with p values < 0.000. Survival rates of the seedlings were very promising, varied from 85.7% (SPF Jeli) to 94.6% (SPF Setiu), whereas SPF Perlis recorded 94.0%. In terms of growth performances, seedlings at SPF Jeli recorded the highest overall height (225.2 cm), followed by SPF Setiu (154.5 cm) and SPF Mata Ayer (147.2 cm). Whereas for the families’ variations, the top three highest heights recorded by the families F4 (199.1 cm), F38 (195.0 cm) and F11 (187.9 cm). Family 27 consistently recorded the lowest height (131.9 cm) throughout the three years of observation. Early findings indicate that S. roxburghii can be grown under various geographical and environmental conditions, and also at even disturbed soil conditions. This preliminary assessment showed that the top three best performances families (F4, F38 and F11) could be promoted as the sources of high-quality planting materials. However, variations within the family (among the progenies) were considered as high. Therefore, growth data are still being collected and monitoring of the growth performances is still ongoing.
