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...

Recording.

Careful recording is an important component of field trialling. In addition to the target traits of interest, all conditions that appear during the trial should be recorded as well as anything unusual or noteworthy. All the data are used in assessing the value of the materials being tested. Recording methods may differ among oil palm research stations. However, some methods are commonly used and these are described in this chapter. Scored traits include yield and yield components (including bunch and oil analysis), growth (height increment), occurrence of common pests, diseases and physiological disorders, nutrient deficiencies and toxicities. New traits include those that can be exploited in developing mechanical harvesting systems in oil palm (fruit colour, long bunch stalks and late fruit abscission or the opposite - total fruit abscission).
