A male sterile is essential for development of hybrid onion varieties. An onion male sterile line ‘Wonye30004’ was developed by Bioenergy Crop Research Center, NICS, RDA in South Korea in 2009. It was used to producing hybrid seed of onion. It is mid-late maturing type and lodging date is on May 15th. It was selected from ‘402AC203’ inbred population and cross-pollinated with a male fertile line, ‘M4’. The populations showed 100% male sterility for subsequent four back-cross generations. ‘Wonye30004’ was numbered as ‘MMS30’ in 2009 and the corresponding male parent is called MMSB30. ‘Wonye30004’ has round bulb shape (Bulb index, 95), cold resistance, and excellent storage quality and average bulb weight is 320g. Lodging date in field test is May 15th. Flowering date is June 1th and flower bud size is 96mm when full bloom. The number and length of flower stalks per bulb are 4 and 116cm, respectively. ‘Wonye30004’ was filed in Korea Seed and Variety Service in 2010. Overall, this line will be useful for onion hybrid seed production and breeding program.
