Abstract: Methods are provided for obtaining a genetically modified plant, wherein the plant exhibits an increased oil yield relative to a corresponding control plant that is not so genetically modified. The methods comprise genetically modifying a plant progenitor cell to cause a decrease in triose-phosphate isomerase activity and an increase in glycerol-3-phosphate dehydrogenase activity. The methods also comprise culturing the genetically modified plant progenitor cell to obtain the genetically modified plant. Also provided are methods for increasing oil yield, comprising genetically modifying a plant to cause, in at least one oil-producing organ or tissue of the plant, a decrease in triose-phosphate isomerase activity and an increase in glycerol-3-phosphate dehydrogenase activity. The genetic modification is carried out across more than a single generation. The genetically modified plant exhibits an increased oil yield relative to a corresponding control plant.

Abstract: Methods for predicting palm oil yield of a test oil palm plant are disclosed. The methods comprise determining, from a sample of a test oil palm plant of a population, at least a first SNP genotype, corresponding to a first SNP marker, located in a first candidate gene region for a high-oil-production trait and associated, after stratification and kinship correction, with the high-oil-production trait with a p-value <0.001 in the population or having a linkage disequilibrium r2 value of at least 0.2 with respect to a first other SNP marker that is linked thereto and associated, after stratification and kinship correction, with the high-oil-production trait a p-value <0.001 in the population. The methods also comprise comparing the first SNP genotype to a corresponding first reference SNP genotype and predicting palm oil yield of the test plant based on extent of matching of the SNP genotypes.
