Field trials in oil palm breeding: a manual.

Book cover for Field trials in oil palm breeding: a manual.

Description

A central objective in Verdant's mission is to develop better, more productive and more sustainable cultivars of oil palm (Elaeis guineensis), rubber and other plantation crops, particularly through plant breeding. Field testing is an essential component in selecting and developing new varieties with superior performance for yield, quality, pest and disease resistance and in meeting new market dem...

Pre-trialling considerations and activities.

Before trialling can begin, various considerations and preparations need to be made. First it is beneficial to know if the trait of interest is governed mainly by genetic or environmental factors. If the trait is controlled by genes which are little affected by the environment then field trials may be set up in a narrow range of environments. If, however, the trait is strongly affected by environment, for example, soil type or climate, then trials need to be more extensive to give an estimate of the environmental and genotype x environment interaction. Multi-locational trials can determine the extent of genetic versus environmental factors involved. Plant breeding is an essential pre-trialling activity as it supplies progeny that have potential for crop improvement (see Setiawati et al., 2018, this series). Field performance testing, in turn, is essential in selecting the progenies or palms sought. Materials for field trialling are seedlings. These are made ready for trialling in the nursery (see Laksono et al., 2019, this series). Coordination is therefore required in preparing planting materials and land preparation for the trial. These aspects are discussed.
