Other claims from this paper (4)
- Observation Chromosome pairing and chiasmata frequency indicate that the genomes of the diploid zinnia species are homologous.
- Association Pigment production in ray flowers segregates as a simple dominant over colorless in F2 progeny of Z. juniperifolia crossed with Z. acerosa.
- Observation The genomic constitution of Z. juniperifolia is designated A1A1.
- Observation Tetraploid zinnia species should tentatively be assigned the genomic formulae given in the paper.
