양파 웅성불임 계통 ‘원예30006’은 2000년에 중생계통인 ‘F2-6’집단에서 웅성불임개체를 선발하여 자식계통인 ‘HMB’를 화분친으로 하여 교배하였다. 2002년에 유지계통을 선발하고 2010년까지 5회 여교잡을 하여 계통의 안정성을 확인한 후 ‘MMS66’으로 명명하고 2010년에 직무육성신품종 심사를 거쳐 2011년에 품종보호출원 하였다. ‘원예30006’의 초형은 직립이며 중생종으로 도복기는 5월 25일, 초장 56 cm, 엽수 8매, 엽초경 12.4 mm로 초세가 중간정도이며 엽초경이 가늘다. 구중은 184 g의 중구형에 속하며, 구형지수 99로 원형이다. 저장성과 내한성이 강하고 노균병에 다소 저항성이 있다. 채종모구의 개화기는 6월 4일, 화경수 4개, 화경장 115 cm, 화구폭 86 mm이며 웅성불임 발현이 안정적이다.
The production of hybrid onion (A. cepa L.) seed is economically feasible using systems of cytoplasmic male sterility (CMS). Therefore, male sterile (A-line) and maintainer (B-line) is essential to development of F1 hybrids. Male sterile line Wonye30006’ was developed by Bioenergy Crop Research Center, National Institute of Crop Science, RDA in South Korea in 2010. The first cross for introduction of CMS was conducted in 2000. Male-sterile parents which were selected from ‘F2-6’breeding lines were pollinated with male fertile line ‘HMB’ (inbred line). The fertility test was conducted in 2002 and maintainer line ‘Mo2005’ was selected. The proportion of male-sterility plants of F1 population was 100% for subsequent four backcross generations. ‘Wonye30006’ was named ‘MMS66’ in 2009 and the corresponding male parent was called ‘MMSB66’. As an mid-late maturing type, lodging date is around May 25th. ‘Wonye30006’ has round bulb and the average bulb weight is 184 g. Plant height and stem diameter are 56 cm and 12.4 mm, respectively. Number and the length of flower stalks per mother bulb are 122 cm and 6, respectively. Flowering date is June 4th and flower bud size is 81.2 mm. Wonye30006 will be used for development of F1 hybrids in breeding program. (no. 4674)
