• 1 Self-pollinate; self-fertilize.

    ‘the flowers never open and pollination is normally by selfing’
    • ‘Flowers of all species under study were selfed to determine the time taken by pollen tubes to reach the ovules.’
    • ‘Inflorescences of flowering plants were selfed and isolated with bags.’
    • ‘Although not in a significant proportion, seeds produced by selfing often show a bimodal weight distribution, with about one-quarter of seeds lighter than others (data not shown).’
    • ‘Accessions generally consist of seed multiplied by selfing a single initial wild-collected individual.’
    1. 1.1Genetics Cause (an animal or plant) to breed with or fertilize one of the same hybrid origin or strain.
      ‘progeny were derived from selfed crosses’
      • ‘These 648 plants, representing selfed progenies of irradiated maize chromosome 9 monosomic addition line plants, were screened for the presence or absence of maize DNA.’
      • ‘From each of the heterozygotes for nonlethal chromosomes, 40 selfed progeny were obtained.’
      • ‘The hybrid plants, used as the female parents, were back-crossed with H. polyrhizus and S. megalanthus, crossed with the diploid H. undatus, or selfed.’
      • ‘A resulting triple-heterozygous resistant-susceptible plant, i.e., a heterozygous plant at the three resistance loci, was isolated and selfed to produce the 27 expected genotypes described in Table 1.’
      • ‘In order to study the inheritance of cytomixis, the cytomictic plants were selfed and crossed as both male and female parents with one of the five control plants under controlled conditions.’
