Other claims from this paper (9)
- Observation Twin embryos were rare despite two ovules per carpel.
- Association Twin embryo frequency correlated with variance in cultivar fertility.
- Association Twin embryo frequency did not correlate with low mean fertility.
- Association Plastids had no effect in the analysis of variance.
- Observation Self and hybrid families supported a genetic basis for twin formation.
- Association Lower parental twin frequency corresponded to fewer offspring families with twins and a lower overall mean.
- Observation A few self and hybrid families reached 16.4 per cent twin frequency.
- Association Twin embryo survival was sometimes poorer than single embryo survival.
- Association Upper twin embryos tended to survive better than lower twin embryos.
