Honors:                     Best-of-class (BC).  We select the best performer in each class, based on the "overall rating".  This rating may not be high, if the class does not perform well; also, the rating may not be significantly different from one or more members of the class. If two or more members of a class received the same overall rating, we used another rating to determine BC.  If only one cultivar was entered in a class, it automatically becomes uncontested BC.  See "Research Papers" 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: Foliage and flower ratings are combined to generate the "overall rating" listed below for each cultivar within its class.  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 rating, if it is a significant problem.  Refer to "Research Papers" for details.  Generally, 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.
 
Note: data and pictures are still being inserted.  Plot numbers are temporarily inserted into the "honors" cell to more easily match up new photographs with the correct cultivar.  Best of class listings are from the previous year, until trial data is analyzed.

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.  Measured in centimeters and inches [cm (inches)].  Values with an "a" are considered significantly greater than those with a "b", "c", etc., and those without a letter are not considered to be significantly different.
3.  Average number of days from sowing to unfurling of the first flower in the plots.  Flowering for alyssum was completed in the flat prior to planting in the field.  Values with an "a" are considered significantly greater than those with a "b", "c", etc., and those without a letter are not considered to be significantly different.
4.  The average of the combined foliage and flower data in the sprayed field as an expression of cultivar quality.  Values with an "a" are considered significantly greater than those with a "b", "c", etc., and those without a letter are not considered to be significantly different.
5.  The average of the combined foliage and flower data in the unsprayed field as an expression of arthropod and disease symptoms and adjusted to account for plant deaths from soilborne pathogens.  Values with an "a" are considered significantly greater than those with a "b", "c", etc., and those without a letter are not considered to be significantly different.
6.  The average of the combined overall foliage/flower rating and overall pest rating.  If plant deaths from soilborne pathogens resulted, this was factored into the rating.  Values with an "a" are considered significantly greater than those with a "b", "c", etc., and those without a letter are not considered to be significantly different.  See Articles, Papers & Reports for further explanation in the reports.
