Title
AN ANALYSIS OF FREQUENCIES OF CHROMOSOME CONFIGURATIONS IN WHEAT AND WHEAT HYBRIDS

Other claims from this paper (9)
- Observation In euploid wheat, homologous chromosome association probability a was essentially unity.
- Observation In euploid wheat, chiasma formation probability c was about 95%.
- Intervention effect Colchicine primarily changed association probability a.
- Observation Observed and expected chromosome configuration frequencies generally agreed in wheat hybrids.
- Observation Wheat hybrids had excess closed bivalents relative to expected frequencies at the expense of multivalents.
- Mechanism The excess closed bivalents suggests that homoeologues are not effectively associated in every cell.
- Observation Homologues were inferred to associate almost certainly in euhexaploid wheat, while homoeologous pairs associated less efficiently.
- Observation Aneuploidy affected chiasma number rather than chromosome association.
- Observation Chromosome 5B deficiency may change chiasma distribution among homoeologues.
