The occurrence of female sterile plants is a very rare phenomenon in oil palm. The sterility in dura is may be due to crossing over and recombination of genes. The female sterile palm is a promising genetic tool for use as the male parent in hybrid palms production. The problem of gene flow is particularly important to the genetic improvement of perennial crop like oil palm. By using female sterile lines there is a possibility to create sterile hybrid plants to control gene flow. The ovule of female sterile plants is aborted but the phenotype of most of the plant is otherwise normal. The inflorescence and flowers of sterile plants are normal and had high pollen fertility. Wild traits are the reservoir of many useful genes/ alleles which can be used to survive climate extremes. Wild traits have very high level of resistance/tolerance to various stresses. To cope with this situation, there is a need to breed new crop cultivars with a broad genetic base capable of withstanding frequent climatic fluctuations and wider adaptability due to adapted gene complex.
