Material preparation.

Abstract

Abstract The aim of oil palm trialling is to evaluate field performance among a range of genotypes and to select those of interest. A basic necessity is the provision of good quality planting material, usually produced from deliberate cross-pollinations. Details of methods in pre-trialling activities, i.e. in crossing, seed production and the production of field-ready planting materials, are given in Kelanaputra et al. (2018), Setiawati et al. (2018) and Laksono et al. (2019), respectively (this series of manuals). Thus, only brief overviews of these operations are given here.
