‘Trounce’ is a new maincrop freezer pea developed for the vegetable processing industry. Its main advantage is its high level of resistance to powdery mildew(Erisyphe pisiDC). It is a mid‐season maturity cultivar resistant to pea common wilt{Fusarium oxysporumf.sp.pisirace 1), pea top yellows virus, and bean yellow mosaic virus. In 15 evaluation trials over 3 years, it has consistently outyielded the standard cultivars. ‘Trounce’ has performed well in quality assessments testing its suitability for freezing. A notable feature of this cultivar is the high proportion of small peas produced.
