Pedigree
Description:
Both CPPSIH 3 01 and CPPSIH 3 20 are Viroflay. The only difference is that they are different seed increases. The old one being from 2010 and the new one being from March 2024. The same seed source may have been used to generate them. They should both be universally susceptible to all named races of spinach downy mildew as of early 2025.
