A new intermediate parent 'Wonye 30002' (Allium cepa L.) was developed by Bioenergy Crop Research Center, NICS in 2009. As a male sterile line, 'Wonye 30002' can be used to hybrid seed production by crossing with pollen parent. The first cross was conducted between male sterile plants of 402AC203 and M1 in 2002. The male sterile line 'Wonye 30002' has circular bulb and bulb weight is 283 g. As early maturing type, lodging date is May 6. Plant height and pseudostem diameter are 43 cm and 15.5 mm, respectively. In seed harvesting characteristics, number of flower stalks and the length are 43 cm and 110 cm, respectively. The flowering date of 'Wonye 30002' is around May 24 and is completely male sterile. 'Wonye 30002' is a promising male sterile line for hybrid bulb onion seed production.
