Breeding For Resistance In California Strawberry To Verticillium Dahliae, Zachary Christman

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Since 1930 the University of California, Davis, has been developing strawberry cultivars that are adapted to the agricultural industry and regional farms. Developing cultivars that require fewer inputs are of significant economic importance in agronomy. Developing a crop resistant to a disease is beneficial for horticulturists since less labor and chemicals are needed for a high yield.⁶

In commercial strawberry cultivars, complete resistance to V. dahlia is extremely rare. The majority of Californian strawberry cultivars are highly susceptible to it.² Over the last 18 years of plant breeding for strawberry cultivars with a high degree of resistance and …

Bois 412/812: Human Genetics—A Peer Review Of Teaching Project Benchmark Portfolio, Colin D. Meiklejohn

UNL Faculty Course Portfolios

Nf04-597 Biosecurity And The Poultry Flock, Dan Mcguire, Sheila Scheideler

University of Nebraska-Lincoln Extension: Historical Materials

What is Biosecurity? Biosecurity is a modern term created out of a need to protect, in our case poultry, from an intentional or unintentional threat from a biological agent. In our everyday management, biosecurity is an endless endeavor to keep viral disease agents and/or the spread of such disease agents at bay. We have learned from our own personal welfare that by keeping our environment clean, i.e., "cleanliness is next to godliness" and by reducing contact with infected people or animals, i.e., "being a good neighbor," we can reduce our chance of catching or spreading disease. This NebGuide discusses what …
