A chrysanthemum plant of the morifolium ramat species having a rapid growth rate reaching a height ranging from about 85 cm. to about 112 cm. within substantially two long-day weeks at 60.degree. F. with internode lengths approximately 30 mm. and a stem diameter of from 4 to 7 mm.;
- a reliable 8 to 12 weeks short-day response in winter light and 45.degree. to 60.degree. night temperature, this plant having a continuous year-round flowering capability producing a profusion of flowers borne in compound lateral clusters;
- each cluster comprising 10 to 14 flowers each having a newly-opened diameter of 70 to 80 mm., a fully expanded diameter of 70 to 90 mm., florets comprising approximately 23 to 30 ray florets of about 35 to 45 mm. long and about 10 to 20 mm. wide and approximately 220-260 disc florets, the disc florets being of a green color (R.H.S. 144B) before dehiscence and yellowing on dehiscence, the average disc diameter being about 20 mm.;
- this plant being further distinguished by its high sensitivity and responsiveness to CO.sub.2 and supplementary light, with bud and flower development at 50.degree. F. or less, by its very rapid apical leaf formation with as much as one leaf per day in high light, by its free branching with rapid and erect shoot development, by having a chromosome count of 54 of which one chromosome is telocentric;
- and wherein the color of the ray florets is one of the group consisting of the R.H.S. designations 4D (Primrose Yellow), 5D (Dresden Yellow), 12D (Aureolin) overlaid with 182A, 11B (Straw Yellow), 14C (Lemon Yellow), 22B (Orange Buff), 23D (Cadmium Orange), 24B, 24C (Tangerine Orange), 26C, 26D (Spanish Orange), 34B, 31B (Burnt Orange), 75C-D, 155D (White), 159B overlaid with 186A, 161C overlaid with 182C and 4C overlaid with 70A.
A chrysanthemum plant named Pale Pink Snapper of the classification morifolium ramat distinguished by having (a) a height of about 99 cm. and a stem diameter of about 6 mm. and being of vigorous and strong upright growth, (b) branching freely with terminal shoots which express buds rapidly under short-day conditions, and (c) having a leaf formation of about one leaf per day in high-light conditions, (d) about a nine-week short-day response to maturity for June flowering at 60.degree. F. night temperature and flowering year around under photoperiod control, (e) the flowers being of daisy capitulum form borne in corymbiform spray clusters and having a fully expanded diameter of about 70 to 80 mm., a coloration of substantially RHS 75C-D, and a chromosome count of 54 with at least one that is telocentric.
Propagating material from a chrysanthemum morifolium ramat plant selected from the group consisting of the plant named Pale Pink Snapper and radiation-induced mutants thereof, including the Snapper cultivars generically named White Snapper, Bronze Snapper, Salmon Bronze Snapper, Yellow Snapper, Dark Salmon Snapper, Pale Yellow Snapper, Apricot Snapper, Copper Bronze Snapper, Pale Salmon Snapper, Salmon Red Snapper, Dark Golden Bronze Snapper, Dark Salmon Bronze Snapper and Bright Yellow Snapper.
