Boxwood Breeding at the U.S. National Arboretum
Fred Gouker • July 18, 2021
Learn more about the development of improved woody ornamental landscape plants with superior ornamental value and that are tolerant to abiotic and biotic stress. Using the boxwood germplasm collection amassed at the U.S. National Arboretum, researchers are screening boxwood accessions for disease resistance, developing screening assays, and studying crossing and seed parameters to create new hybrids as part of a long-term breeding program to develop blight resistant boxwood cultivars.

It is neither economically sustainable nor environmentally acceptable to make multiple fungicide applications to protect boxwood, a key nursery crop and iconic landscape plant, from boxwood blight.
This educational session aims to equip nursery producers, gardeners, and plant health professionals with vital knowledge and strategies to combat the pervasive threat of Calonectria pseudonaviculata, the fungus responsible for the devastating boxwood blight. Boxwood blight, a serious concern for the horticulture industry, jeopardizes the health and viability of boxwood plants, significantly impacting the ornamental plant market. Addressing this issue, the webinar will delve into the critical control points in nursery production, emphasizing effective sanitation practices to prevent and manage the spread of this disease. Attendees of the webinar can expect to gain: An understanding of the lifecycle and spread of Calonectria pseudonaviculata. Insight into the latest research and developments in boxwood blight control. Practical guidance on implementing effective sanitation and preventive measures in nursery production. Strategies for identifying critical control points to mitigate the risk of boxwood blight in their operations. This webinar is essential for anyone involved in the cultivation, care, or management of boxwood
