Poster Session 23—Vegetable Crops: Cultivar Evaluation 19 July 2005, 1:15–2:00 p.m. Poster Hall–Ballroom E/F
The genus Salix L. (Salicaceae Mirb., willow) comprises ≈450 species ( Argus, 2010 ) with numerous subspecies, varieties, forms, natural and artificial hybrids, and cultivars. Genus diversity and a wide natural distribution from the tropics to the
Huylenbroeck and Van Bockstaele, 2001 ; Stuefer and Huber, 1998 ). For breeding programs, turfgrass cultivars, and novel turfgrass accessions must be evaluated to improve on specific traits. Typically, these collections are subjected to rigorous selection
production chain of sweet peppers and, as sweet pepper crops of different growers are synchronized, it causes fluctuations in the price of sweet peppers as well ( Gottschall, 2001 ). Sweet pepper cultivars are known to differ in fruit set percentage
has been identified, as Nuessly and Nagata (1994) reported that ‘Valmaine’, a romaine lettuce cultivar, had a high level of resistance to SL. This cultivar was later found to be resistant to BCB ( Huang et al., 2002 ; Sethi et al., 2008 ) and two

growers in cold climates ( Kronenberg 1975 ). Planting date and cultivar selection affect total yield potential, timing of bud enlargement, and optimal harvest date ( Everaarts and Sukkel 1999 ). The commercial availability of cultivars has changed
resistance, but has not focused much on abiotic stresses of creeping bentgrass such as drought stress ( Meyer et al., 2017 ). Creeping bentgrass cultivars are synthetic because the species is highly outcrossing—meaning, there can be genetic variation within
elderberry has been studied only marginally. A few improved cultivars were introduced from southeast Canada and New York many decades ago ( American Society for Horticultural Science, 1997 ). Only a handful of minor, dated reports ( Craig, 1978 ; Hill, 1969
University of Wyoming Lander Experimental Fruit Farm Orchard contained 1700 trees of 175 cultivars by the early 1920s and contained the largest cultivar diversity in the state. Between these two orchards, only 127 trees of the original 4700 remain ( Miller
