As noted in the Foreword to this Series, a central objective in Verdant Bioscience’s mission is to sell better varieties of oil palm, rubber and other plantation crops through plant breeding. Essential to this objective is that the seedlings fulfil as far as possible their genetic potential, while at the same time being part of a sustainable plantation system. Therefore, one of the major breeding objectives for oil palm improvement, in line with the major need for sustainability, is the development of disease-resistant var - ieties. Ganoderma is the biggest disease problem of oil palm in South-east Asia and the number one target for disease resistance breeding in this part of the world. Interestingly, in many of the African countries, the major disease problem is Fusarium rather than Ganoderma . Effective breeding requires the identification of germplasm resistant to Ganoderma and the screening and selection of progenies and palms from crossing programmes in order to improve the resistance levels in the commercially grown seed. Early and rapid screens are needed to allow a sufficiently effective and high selection pressure to be imposed in order to increase the chances of identifying us- able levels of resistance. Here, we present methods in a seedling screen for Ganoderma resistance/susceptibility in oil palm, which means large num- bers of seedlings can be screened at the nursery level, and hence allow large numbers to be handled. The results of such selection will give palms, fam- ilies and populations that can be used in further selection or advancement to commercialization. These then will be grown in a system that also uses appropriate husbandry techniques and biological controls, which in unison prevent or reduce Ganoderma incidence, in other words, in integrated man- agement systems. Our target audiences are students and researchers in agri- culture, plant pathologists, plant breeders, growers and end-users interested in the practicalities of oil palm breeding.
