| 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. |
