Abstract
A new intermediate parent 'Wonye 30001' (Allium cepa L.) was developed by Bioenergy Crop Research Center, NICS in 2009. As a male sterile line, 'Wonye 30001' could be used for hybrid seed production by crossing with pollen parent. The first cross was conducted in 2000. Male sterile plants were selected from 'Ginque' breeding lines and fertile plants were selected from YG-1-1. The male sterile line 'Wonye 30001' has circular bulb and bulb weight of 260 g. As mid-late maturing type, lodging date is around May 20. Plant height and stem diameter are 57 cm and 15.9 mm, respectively. In seed harvesting characteristics, number of flower stalks and the length are 6 and 135cm, respectively. Flowering date of 'Wonye' is May 23 and is completely male sterile. 'Wonye 30001' is a promising male sterile line for hybrid bulb onion seed production.
