Other claims from this paper (10)
- Observation Crosses produced 9052 new allohexaploid hybrid seeds.
- Association Female and male parent genotypes affected crossing success rate.
- Observation F1 hybrids had mid parent seed fertility heterosis ranging from -64 to 275 %.
- Observation F1 hybrids had best parent seed fertility heterosis ranging from -79 to 241 %.
- Observation Most F1 hybrids had similar amounts of copy number variation events to their parents.
- Observation Most copy number variation events were inherited directly from a parent.
- Observation Combining allohexaploid types by hand pollination was feasible without extra embryo survival measures.
- Observation Novel hybrids had stability similar to their parents.
- Mechanism The authors infer no selection against CNVs during hybridization.
- Association Increased heterozygosity did not immediately improve seed fertility.
