Classifying Cider Apple Germplasm Using Genetic Markers for Fruit Acidity

Susceptibility of fruit from diverse apple and crabapple germplasm to attack from apple maggot (Diptera: Tephritidae).

Apple maggot, Rhagoletis pomonella (Walsh) (Diptera: Tephritidae), is a pest of major concern to apple, Malus x domestica (Borkh.) production in eastern North America. Host plant resistance to apple maggot among apple germplasm has been previously evaluated among a small number of exotic Malus accessions and domestic hybrid selections. However, a large number of exotic accessions housed in USDA...

Genetic diversity analysis of tree peony germplasm using iPBS markers.

We examined the genetic diversity of 10 wild species (populations) and 55 varieties of tree peony using inter-primer binding site (iPBS) markers. From a total of 36 iPBS primers, 16 were selected based on polymorphic amplification. The number of bands amplified by each primer ranged from 9 to 19, with an average of 12.88 bands per primer. The length of bands ranged from 100 to 2000 bp, concentr...

Genetic Markers and Horticultural Germplasm Management

This paper is adapted from the text of a seminar of the same title presented as part of the Workshop on Sustainability of Vegetable Breeders’ Genetic Resources, 26 July 1993, at the 90th Annual Meeting of the American Society for Horticultural Science. It represents the distillation of a more extensive treatment of genetic markers and germplasm management (Bretting and Widrlechner, 1995). Disci...

Cryptosporidiosis Associated with Ozonated Apple Cider

We linked an outbreak of cryptosporidiosis to ozonated apple cider by using molecular and epidemiologic methods. Because ozonation was insufficient in preventing this outbreak, its use in rendering apple cider safe for drinking is questioned.
