Other claims from this paper (6)
- Intervention effect Tetraploid inbreds and hybrids generally had longer, wider leaves and larger stalk diameters than their diploid counterparts.
- Intervention effect Tetraploid inbreds and hybrids generally had higher grain and stover moisture than diploid counterparts.
- Intervention effect Stover, cob and grain yields were greater for diploid inbreds and hybrids.
- Intervention effect Total biomass yield was greater for diploid inbreds and hybrids.
- Observation Ranking of genotypes at the diploid level is not necessarily indicative of rankings at the tetraploid level.
- Recommendation The results do not support using tetraploids to increase total biomass production in maize.
