RATINGS
Honors:                     Best-of-class (BC).  We select the best performer in each class, based on the "overall performance rating".  This rating may not be high, if the class does not perform well (indicating a possible need for improvement in the class).  The rating  may be significantly different from one or more members of the class. If two or more members of a class received the same highest overall performance rating, we used another rating (such as overall foliage/flower rating or flower average rating) to determine BC.  If only one cultivar was entered in a class, it automatically becomes uncontested BC.  BC is evaluated in future trials against the performance of new entries in the same class.  Refer to a report in "Articles, Papers & Reports" for detailed information. In addition to BC, other "honors" received for these cultivars may be added to BC at a later date, time permitting.  Seed companies may forward these honors (awards) to Rick Kelly. 
Rating System: The rating is a 1 to 7 scale: 7- all foliage and flowers free from defects; 4- average foliage and flower condition, minimal plant defects or pest damage to tissue, but  still acceptable; 1- foliage and/or flowers with severe defects and/or severely infested with pests and damage unacceptable, making plant undesirable.  Plant death due to soilborne pests may be factored into the overall performance rating, if it is a significant problem.  Refer to a report in  "Articles, Papers & Reports" for details.  If listed, ratings with an "a" are the best in a class.  If cultivars share the same letters, those ratings are considered to be similar to each other.  If there are no letters, there is only one cultivar in a class or all the members of a class have similar ratings.

Winter

    This crop will be reevaluated in spring 2006, because healthy plugs, normally excellent for planting for other crops, were too well developed for this specific crop, resulting in retarded development in the field. All conditions being equal, the doubles, ‘Sapphire Double White’ (best-of-class) and the new ‘Tiramisu Double Cream’, were the best looking cultivars in a special comparison of double-flowered dwarf classes.

    Pest symptoms. No plants succumbed to Fusarium crown rot or other soilborne pathogens, unlike vinca and pentas. No foliar or floral diseases were observed. Armyworm damage was sporadic and did not continue into mid July

ROK
1. The number of weeks from seed sowing to the date the plant was photographed.  Photographs were taken in a field sprayed on demand as needed, after scouting for pests, and a field that is not sprayed at all. 
2.  Average number of days from sowing to unfurling of the first flower in the plots.
3.  The average of the combined foliage and flower data in the sprayed field as an expression of cultivar quality; rating scale: 1 = poor to 7 = excellent (details above).
4.  The average of the combined foliage and flower data in the unsprayed field as an expression of arthropod and disease symptoms; rating scale: 1 = poor to 7 = excellent (details above).
5.  The average of the combined overall foliage/flower rating and overall pest rating; rating scale: 1 = poor to 7 = excellent (details above).  If plant death from a soilborne pathogen resulted, this was factored into the rating.  See Articles, Papers & Reports for further explanation in the reports.
