Other claims from this paper (10)
- Observation Corn and perennial teosinte nDNA densities were similar.
- Observation Corn and perennial teosinte nDNA densities were significantly greater than those of tripsacum and annual teosinte.
- Observation Tripsacum and annual teosinte did not differ in nDNA densities.
- Observation Corn-tripsacum hybrid nDNA densities resembled those of the higher parent.
- Observation Small significant differences in parental base composition did not preclude corn-tripsacum hybridization.
- Observation In grasses nDNAs were resolved as single bands without satellites.
- Observation In grasses nDNAs had relatively high guanine and cytosine contents.
- Observation Chromosome number of T. andersonii is 2n = 64, reported for the first time.
- Observation Chromosomal knob numbers of Tripsacum accessions ranged from 0 to 40.
- Observation One Tripsacum accession had 3 to 4 B chromosomes.
