Other claims from this paper (4)
- Observation Heterosis was not exhibited by tomato yield or yield components at any of the four nutrient levels in the controlled-nutrient experiment.
- Observation The total heterosis phenomenon in tomato was classified as nutrient-dependent: present under field conditions but absent under the nutritional restrictions of the controlled-nutrient experiment.
- Mechanism Heterosis hypotheses 1 and 2 were rejected by the controlled-nutrient experimental results.
- Mechanism It is speculated that the indeterminate pattern of plant development responsible for yield and its components is due to two major gene systems.
