A chromatographic study of leaf phenolic compounds in two Citrus interspecific hybrids and their parents

Two interspecific F1 hybrids of Citrus species were examined for inheritance of leaf phenolic compounds. Both the hybrids revealed a reduced number of compounds compared with those of the parents. In addition, the spot pattern of each taxon offered a basis for analysis of inheritance pattern. Due to the production of clones with a consequent reduction in the number of sexual offspring by nucellar embryony in these plants, the unusual pattern of inheritance observed in the hybrids could not be categorized as either a product of disturbed Mendelian ratios or as transgressive segregation affecting only a few individuals in the segregating generations.
