Other claims from this paper (3)
- Observation Of the 12 genotypes, five were classified as heat-tolerant and four as heat-susceptible based on the heat susceptibility index across two experiments.
- Observation 25 metabolic markers discriminated between heat-tolerant and heat-susceptible genotypes exposed to the heat treatment.
- Observation The variation identified in this germplasm indicates that genetic variation exists within B. napus for heat tolerance, enabling genetic gain.
