Recent advances in genetic improvement of coconut yield
The general method for genetic improvement of yield in coconut as adopted by the Institut de Recherches pour les Huiles et Oleagineux (IRHO) has been already described in several articles. It comprises a stage in which genetic variability is accumulated by prospecting and collection, followed by comparative tests of hybrids between different ecotypes to select the best ones, and improvement of these superior hybrids. Multisite performance trials allow an assessment of environmental effects and disease incidence. As a result of recent advances in modem plant breeding, new methods can now be used for many species. They are particularly attractive when it comes to surmounting the biological constraints limiting coconut improvement. This paper outlines the new strategies developed and the programmes set up in order to produce above-average clones through vegetative propagation by in vitro culture, as well as to obtain new varieties from gamete cell culture through androgenesis and gynogenesis.
