Genetic analysis in Chrysanthemum morifolium. II. Flower doubleness and ray floret corolla splitting

Summary

The inheritance of flower doubleness and floret corolla shape was studied in 70 F1 populations from 16 parents. Singleness is partially dominant over doubleness. The overall segregation for doubleness in crosses of the type double × single was 29% single, 58% semi double and 12% double. The percentages varied with the parents.

The anemone flower type is inherited as if it were a single. Crosses between plants with ligulate (split lengthwise) and tubular corollas produced ligulate, tubular and intermediate types in various ratios depending on the parents used. Flower doubleness and corolla shape are not linked.
