e0“Photochemical activity of isolated mesophyll chloroplasts was measured as Hill reaction activity (HRA) and photosystem 1 (PS1) activity in three diallel crosses of maize (Zea mays L.) inbred lines and F1 hybrids. Statistically significant differences between genotypes together with positive heterotic effect in F1 generation were found for both traits studied.”

Other claims from this paper (6)
- Observation Maize genotypes differed significantly in Hill reaction activity and showed positive F1 heterosis.
- Observation Genotype differences in chloroplast activity were more pronounced per leaf area or dry matter than per chlorophyll content.
- Observation Genetic and non-genetic components of variation in photochemical activity were present in all three maize diallel crosses.
- Mechanism Positive F1 heterosis probably arises from positive dominance non-additive effects.
- Observation Additive genetic effects were highly significant.
- Observation Reciprocal maize crosses did not differ.
