There are over 30,000 named daylily cultivars in existence today. Ancient Chinese used the plant for nutritive and medicinal qualities. The Greek name Hemerocallis means beautiful for a day. Daylilies demonstrate potential in food service due to the range of color, fragrance, flavor, and textural varieties. The objective was to quantify by descriptive analysis the attribute descriptors for two edible daylily cultivars, i.e., `Rosie Meyer' and `Siloam Powder Pink' and to provide data indicating optimum month for consumption of these two cultivars of daylilies. Blooms were harvested during early morning hours over 5 months (May to September). Six panelists were trained utilizing Quantitative Descriptive Analysis for 6 months on the sensory attributes of `Rosie Meyer' and `Siloam Powder Pink' cultivars. Training consisted of determining attribute categories as well as intensity ratings for references. Attribute categories included appearance, odor/scent, handfelt texture, oral texture, basic taste(s), flavor, mouth feeling factors, and chew rate. Results showed attribute categories with descriptors for `Siloam Powder Pink' as odor/scent, flavor, mouth feeling factors, and oral texture as having a significant difference (P < 0.05) for the evaluation months. `Rosie Meyer' demonstrated significant differences (P < 0.05) for the evaluation months in attribute categories for appearance, odor/scent, flavor, oral texture, and mouth feeling factors. The optimum month for consumption of `Rosie Meyer' was September (P < 0.05); `Siloam Powder Pink' was July (P < 0.05). These results provide a descriptive language for daylily (Hemerocallis sp.) cultivars `Rosie Meyer' and `Siloam Powder Pink'. The optimum month for consumption to obtain the fullest range of desirable attributes will provide the food and horticultural industry with added information by which to market these cultivars.

There are >52,000 cultivars of daylilies (Hemerocallis spp.), some of which the ancient Chinese used for nutritional and medicinal purposes. Daylilies have tremendous potential in foodservice due to the range of color, fragrance, flavor, and textural varieties. The objective was to quantify by descriptive analysis the attribute descriptors for two edible daylily cultivars; that is, `Rosie Meyer' and `Siloam Powder Pink,' and to provide data indicating the optimum month for consumption of these two cultivars of daylilies.

The optimum month for consumption of `Rosie Meyer] was September (P < 0.05); for `Siloam Powder Pink,' it was July (P < 0.05). These results provide a descriptive language for daylily cultivars `Rosie Meyer' and `Siloam Powder Pink.' The optimum month for consumption to obtain the fullest range of desirable attributes will provide the food and horticultural industries with added information by which to market these cultivars.

Abstract

Roots from 8 advanced generation breeding lines of carrot (Daucus carota L.) repeatedly selected for high or low total soluble solids content, and 2 selections of Tmperator 58', one with high and one with low soluble solids, were evaluated for perceived sweetness and eating quality by taste panels. Most taste evaluations were made using the Quantitative Descriptive Analysis method. Two breeding lines, 5158 and 5164, had high levels of solids (X's averaging 10.4 and 10.8% respectively) but were downgraded in perceived sweetness in panel evaluations. The ranking of the other lines according to their mean preference scores for perceived sweetness was related to total soluble solids content. Bitter taste and harsh flavor characteristics were associated with 5158 and 5164. No perceived sensory differences were found between the high and low selections of Imperator 58 by a technological panel. A consumer preference taste panel, however, showed a slight preference for eating carrots from the high solids selection. The background constituents of carrot flavor appear to play an important role in the perception of sweetness at all levels of soluble solids.
