Taxon groups are the verbatim names found in the abstracts (case-insensitive), not normalised: maize, corn and Zea mays are separate groups here. The Organism view merges them through NCBI Taxonomy.

Other claims from this paper (6)

Observation Yield, flowering, height, panicle and grain traits were highly heritable.
Association Additive genetic variance declined over successive generations.
Association Nonadditive genetic variance declined more than additive variance.
Association Genotype rankings changed little across generations.
Observation Specific combining ability showed no clear trend.
Association The best crosses tended to have parents with divergent general combining abilities.
