First venalization was of 10-12 week old seedlings in rootrainersTM (in SunshineTM #4 media) for a minimum of 4 months at 4 C with 12 hrs light and watered as necessary.
Subsequent re-vernalizations were of adult plants, trimmed and cleaned of debris, in 2 gallon pots for a minimum of 4 months at 4 C, 12 hrs light, and watered as necessary.
Some accessions require 2 or more re-vernalizations for the entire population to flower.
If bolted plants produced a good quantity of seed they were thrown out;only non-bolted plants were revernalized. If bolted plants didn't produce a good quantity of seed, all plants were saved and revernalized. Bolting 2 data is % of plants vernalized.
ErysipheDescriptor data collected from plants grown for seed increase in the greenhouse. Ratings for Erysiphe susceptibility were made based on natural infection. No inoculations were made.
