Aguedilla is a short-day strawberry (Fragaria ×ananassa Duch.) cultivar obtained by the Spanish public breeding program (Agreement CC01-0008-F1). 'Aguedilla' produces excellent extra-early, early, mid-season, and late-season large-sized, wedge-shaped fruit, and a low percentage of second quality fruit. An agronomic and sensorial characterization of this new cultivar, in comparison with the well-adapted cultivars 'Camarosa', 'Medina', and 'Ventana', was undertaken during the 2002–03 and 2003–04 crop seasons.

Plum production in the Southeastern United States is limited because cultivars are susceptible to bacterial canker (Pseudomonas syringae), bacterial fruit and leaf spot (Xanthomonas pruni), black knot (Apisporina morbosa) and plum leaf scald (Xylella fastidiosa). Evaluation of four new cultivars developed by the Alabama Agricultural Experiment Station indicated that AU-Rubrum, AU-Rosa and AU -Cherry were resistant to all the diseases listed, and AU-Amber was resistant to all excapt A. morbosa. Disease ratings were made on trees in six experimental plantings in Alabama, in Georgia test plantings and in grower trials.

Sun coleus (Solenostenum scutellarioides) are commonly used in the southern landscape. However, with the introduction of new cultivars, producers and consumers may be unaware of the selection and landscape performance of sun coleus. Sun coleus cultivars were trialed under landscape conditions at the South Mississippi Branch Station in Poplarville, Miss., in 2000 and 2001. The objective of this study was to evaluate sun coleus cultivars based on landscape performance criteria including flowering, durability, vigor, uniqueness, and insect and disease resistance. Cultivars performing well over both years included `Ducksfoot Red,' `Ducksfoot Tricolor', `Ducksfoot Yellow', `Sunflower Red', `Pineapple', Mardi Gras', and `Saturn'.

The Plant Patent Act of 1930 was a tremendous step forward in the development of new cultivars for ornamental horticulture and for the benefit of the American public. The `Peace' rose, PP 591, was the single breakthrough that had maximum impact. Prom the Plant Patent Act, other forms of breeders' rights were spawned worldwide, including our own Plant Variety Protection Act (PVPA). Proof of the success has been the increasing use and acceptance of plant patents and the lack of challenges to the act and plant patent litigation.

Seeds from arborvitae, Thuja occidentalis L., cultivars were grown to determine phenotypic variations which might be useable as new cultivars. Seeds were germinated and grown under greenhouse and lath house condition. Many seedlings from isolated plants of T. occidentals `Hetz Midget' and `Holmstrup' were similar or identical to the parent plant (98% and 58%, respectively). Seedlings grown from seeds of plants in a mixed planting produced seedlings similar to the seed parent as follows: `Hetz Midget' 100%, `Minima' 78%, `Little Giant' 0%, `Sherwood Moss' 11%, `Spiralis' 24%, `Hoseri' 36%; cultivars that produce a high percentage of true to type seedling could be propagated sexually.

Species and cultivars of Dieffenbachia Schott. (Araceae Juss.) have been important ornamental foliage plants for many decades. Their attractive foliar variegation, adaptability to interior environments, and ease of production are major reasons for their importance as ornamental foliage plants. Approximately 20 cultivars are commercially produced in Florida. Previously, most new cultivars were clones introduced from the wild or chance mutations of existing cultivars. Currently, cultivars are introduced into production from plant breeding programs (Henny 1995a, b; Henny and Chen, 2003; Henny et al., 1987). The hybrid Dieffenbachia `Sterling' was developed by the tropical foliage plant breeding program at the Mid-Florida Research and Education Center.

Chestnut (Castanea sativa Mill.) is an important crop in Spain. This inventory of chestnut cultivars complements previous studies. We have located 152 chestnut cultivars in 131 municipalities covering 108.6 ha, with 72 new cultivars in addition to the 80 previously found. Fewer than 50% of these cultivars are extensively cultivated. Chestnuts in Spain are grown from sea level to 1100 m, but are more frequent between 200 and 800 m on northern-facing slopes. Most of the chestnuts are harvested from 25 Oct. to 10 Nov.
