摘要

'Minkui 1' is a new ornamental sunflower variety developed by hybridizing, inbreeding and backcrossing. The new variety was confirmed to be a hybrid offsping by RAPD molecular marker analysis. The flower color of ' Minkui 1' is significantly different from their parents with orange ligulate petals, green discs, brown tubular flowers, yellow pollens, yellow-green layered flowers and stable ornamental characteristics. The results obtained from the cultivation at various sites for several years showed that it had a growth period of 88~115 d, Its plant height was 115~172 cm with faceplate diameter of 7.5~8.2 cm, flower diameter of 13.5~15.8 cm, petal number of 33~40, cut flower lifespan of 9~13 d and provided a cutting output of 90 000~120 000 pieces/hm2. 'Minkui 1' could be used for ornamental cut flower production or garden landscape cultivation, or for open ground cultivation in frost-free areas and simply protected cultivation in winter in other areas. 'Minkui 1'was passed the provincial appraisal in 2011. The instruction manual for cultivation is also available.%‘闽葵1号’系利用杂交、自交、回交等育种途径选育出的观赏向日葵新品种.结果显示:该品种经RAPD分子标记鉴定其是亲本的杂交后代,其花色与其父母本差异明显,表现为舌状花瓣黄橙色,花盘绿色,管状花褐黄色,花粉黄色,花朵黄绿层次分明,观赏性状稳定.经多年多点试验结果表明:该品种四季种植,全生育期为88～115 d,株高为115～172cm,花盘径为7.5～8.2 cm,花径为13.5～15.8 cm,花瓣为33～40枚,瓶插寿命为9～13 d,切花产量为9.0～12.0万枝/hm2. ‘闽葵1号’可作切花生产或庭院景观种植观赏,适宜在无霜地区露地栽培,其它地区冬季简易保护栽培.于2011年12月通过福建省林木品种审定委员会审定,并总结其配套栽培技术的要点.
