2.1. Field experiment
The present experiment was conducted in Changnyeong county(35◦N, 128◦E), in southeastern Korea, in 2010–2011 growing season. In the county, onions were grown on a total of 1152 ha(KOSTAT, 2012). Experimental sites came from 16 long-term onion growing fields. Fourteen F1 hybrid onion cultivars (Turbo,E-joeun, Premium gold, etc.) and two open-pollinated cultivars (Changnyeongjunggo, Chunjujunggo) were intermediate-day onions in bulb development, and mid or late maturing type in maturity. The onion seeds were sown from late August to mid September,transplanted from late October to early November at a plant density of 33.3 ± 2.3 individuals m−2, and onion bulb were harvested from 3 to 9 June, when 80–100% of the plant tops had broken over at the neck.
