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
Note:  This trial was conducted under 30 % shade in Bradenton with previously fumigated beds that had plastic mulch removed before the research center relocated to Balm, Florida.  In order to accommodate all the cultivars entered for evaluation, only three plants/cultivar/plot could be planted.  Each plot was closely planted to its neighbor, requiring that areas of many plot photographs be blocked out to exclude plants that are not part of the plot and might cause confusion.  There are three plots grown for each cultivar evaluation.  For this crop, all plots in row 1 were selected for display, while any better plots from row 2 or 3 are also displayed for comparison.

Begonia × hybrida

    In this evaluation of a new uncontested rose/white class cultivar, we conducted a special comparison with a Begonia ×hybrida pink class (established in spring 2004).  Both cultivars qualified for display in our best-of-class public gardens with foliage/flower ratings > 4.5 and overall performance ratings > 5.0 and will be added to our Best of the Best-of-class spring list.

Comments: New entry for 2005.  ‘Emperor Red’ replaced ‘Eureka Green Leaf Scarlet’ as best-of-class, due to fuller foliage between late May and early June, and more uniform flowering in late May.  Leaf spot symptoms were very minor and sporadic on ‘Emperor Red’.  Both cultivars experienced equally low plant death from soilborne disease.

Emperor Rose’ did not replace ‘Bayou Rose’ as best-of-class, because the latter had slightly higher overall performance rating than ‘Emperor Rose’; however, performance looked very similar, the largest difference foliage fullness and uniformity occurring between late May and early June.  More plant death from soilborne disease occurred to an equal degree to both cultivars in this class and exceeded all other classes of this begonia crop, thus having a greater impact on overall performance ratings values.
