Other claims from this paper (11)
- Observation Individual beet root size and sugar content differences showed no evidence of inheritance.
- Association Sugar percentage or quantity in ordinary-sized roots did not correlate with seed yield.
- Association Seed yield did not correlate with mean progeny sugar percentage.
- Method / resource Within-family fluctuation exceeded real family differences, but replication distinguished them.
- Observation Areas within an apparently uniform field differed by 2 per cent sugar.
- Association Sugar percentage and sugar yield varied independently among sugar-beet rows.
- Association Mean root weight per row increased with sugar yield.
- Association Mean root weight per row decreased with sugar percentage.
- Intervention effect Stopping selection for one generation caused no deterioration in sugar percentage and an apparent gain.
- Intervention effect Continuous selection did not improve sugar yield or sugar percentage.
- Observation Good and poor beet families both transmitted average qualities.
