Verbatim
e0“The progeny of a 7 x 7 diallel cross between plants randomly selected from a segregating tetraploid setaria population (S. sphacelata var. sevicea and var. splendida) was studied”
e7“The data suggested that resistance may be controlled by a gene exhibiting tetrasomic inheritance with two alleles necessary for expression of a high order of resistance”

Other claims from this paper (8)
- Observation General combining ability variance for yield was of a high order in the Setaria population.
- Association Yield showed a strong positive genetic correlation between seasons.
- Method / resource Variance estimates from analysis of variance and from parent-offspring regression were comparable.
- Observation Genetic variance for days to flower and flower head number was strongly and consistently additive.
- Association Genetic correlations between seasons and years for days to flower were positive and indicated that genetic differences in flowering were not strongly confounded by environmental effects.
- Association Dry matter yield was genetically correlated with flower head number and hence earliness to flower.
- Association Days to flower was genetically correlated with flower head length.
- Observation Resistance to Pyricularia grisea was under genetic control in the Setaria progeny.
