Peat Pellet Inoculation: A Potential Rapid Screening Method for Fusarium Resistance in Cucumis melo L.
Cucurbit Genetics Cooperative Report 6:43-44 (article 20) 1983 Richard N. McArdle and Stephen A. Kendall Department of Horticulture, University of Maryland, College Park, Maryland 20742 Greenhouse tests for Fusarium resistance in muskmelon typically involve inoculation by dipping young melon plants into spore suspensions (2, 3) or growing in infested soil (1). These methods are time-intensive, cumbersome, and […]
