- Intervention effect Space flight reduced germination percentage versus the check.
- Intervention effect Space flight reduced seedling survival rate versus the check.
- Intervention effect Space flight reduced seed setting rate versus the check.
- Intervention effect Space flight caused less physiological damage than gamma irradiation.
- Observation Some cultivars segregated for grain color in M 1.
- Observation Plant height and heading date segregated more strongly in M 2.
- Association Mutation frequency and mutagenic efficiency varied with genotype.
- Association Mutation frequency and efficiency varied by mutation character after either treatment.
- Observation Many mutants with desirable agronomic traits were obtained in M 2.
