- Observation A yellow mutation of sunflower arose in the F2 generation.
- Observation A white mutation of sunflower arose later, in the F5 generation.
- Observation Both pigment-deficient sunflower mutations are inherited as single recessive factors.
- Association Albino strains of sunflower form chlorophyll during seedling stages when grown at low light intensities.
- Association Chlorophyll is destroyed in albino sunflower strains under bright illumination.
- Association Once bleached, albino sunflower strains appear to lose the capacity for chlorophyll formation.
- Observation The yellow sunflower mutant contains xanthophyll.
- Observation No traces of carotene were found in the yellow sunflower mutant.
- Observation Flower color of the yellow sunflower mutant is normal.
- Observation The flowers of the white sunflower mutant have no apparent pigmentation.
- Observation The growth pattern of grafted yellow sunflower mutants is normal.
- Observation Grafted yellow sunflower mutants have a stiffer and woodier condition.
- Observation Grafted yellow sunflower mutants have a greater resistance to wilting.
- Observation Grafted white sunflower mutants show the same stiffer, woodier and wilt-resistant characteristics.
- Observation The white sunflower mutant has a pronounced reduction in leaf size.
- Observation Both sunflower mutants set viable seeds after grafting onto green host plants.
