Other claims from this paper (7)
- Method / resource An SC karyotype identified each maize SC and linked it to a linkage group.
- Method / resource Maps were produced from 4267 RNs on 2080 SCs.
- Association RN frequency correlated closely with chiasma frequency and SC length.
- Observation The RN map was about twofold shorter than most maize linkage maps.
- Observation Relative lengths of individual bivalent maps corresponded well.
- Observation Each bivalent had a unique crossover distribution.
- Observation RN frequency at knobs was similar to or above average SC frequency.
