Other claims from this paper (12)
- Observation Reciprocal crosses with embryo or ovule culture produced interspecific hybrid plants.
- Observation Using A. fistulosum as seed parent produced far fewer hybrid plants per pollinated flower.
- Observation Hybrid plants frequently showed the reported chromosome pairing configurations at meiotic metaphase I.
- Observation Tetrads, dyads and heptads were observed at the tetrad stage.
- Observation Hybrid anthers had fully developed, aborted or mixed forms.
- Observation Fully developed hybrid anthers contained unreduced spherical pollen grains.
- Observation Hybrid pollen stainability ranged from 13 to 65%.
- Observation Backcrossing to A. fistulosum yielded no plants.
- Intervention effect Colchicine treatment produced chromosome-doubled hybrid plants.
- Observation A chromosome-doubled derivative of a fully developed-anther hybrid had 64% pollen stainability.
- Observation That chromosome-doubled derivative produced no seed under open pollination or a cross with A. fistulosum pollen.
- Observation The chromosome-doubled derivative of an aborted-anther hybrid had aborted, pollen-sterile anthers.
