小苍兰新品种‘紫依’的选育

Breeding of Freesia hybrida Ziyi

  • 摘要:
    目的 选育花色新颖、适应性强、多用途的紫色小苍兰新品种,以丰富小苍兰花色类型,满足小苍兰切花、盆栽及景观应用等多样化需求。
    方法 以福建省认定品种‘曙光’为母本,以荷兰引进品种‘Rose Marie’为父本进行杂交,根据育种目标筛选出杂交F1优良单株Y1P1-2,经多代无性系繁殖、植株优选、生物学性状稳定性和一致性观测评价、SRAP分子鉴定,证实Y1P1-2 无性系为其父母本的真实杂交后代,定名为‘紫依’。开展品比试验和多点试验,以明确‘紫依’的栽培适应性、种球和切花产量。
    结果 育成小苍兰新品种‘紫依’(Freesia hybrida ‘Zi Yi’),其花被片上表面为亮紫色(RHS:N87C),花喉部上表面为淡黄色(RHS:6D)。福州地区种植期为9月下旬至10月上旬,始花期为2月下旬至3月上旬,花期35~40d。‘紫依’平均叶长 37.34 cm、花茎长38.66 cm、具3~4个分枝、主花序长8.75 cm、主花序小花数9.56朵、花径4.31cm、繁殖系数为5.5~6.5。多点试验表明,‘紫依’在福州、福清等3地种植时,花色、花型等性状和种球繁殖均表现一致且稳定,亩产商品开花种球2.46万粒,每667m2产切花5.39万支,种球和切花产量稳定。
    结论 小苍兰新品种‘紫依’具有花色新颖、性状稳定、栽培适应性强、景观应用效果好等特点,具有商业开发应用潜力,可在福州地区及具有相似气候条件的地区露地推广种植。

     

    Abstract:
    Objective A new variety of novel-color and highly-adaptable freesia was bred to meet the diverse market demand for cut flowers, potted plants, and landscaping.
    Method The Fujian-certified Freesia hybrida Shuguang as female parent and the Netherlands-origin F. hybrida Rose Marie as male parent were used for the hybridization of an F1 hybrid, Y1P1-2. After generations of asexual reproduction, selection, biological stability test, consistency observation, and SRAP molecular identification to confirm the hybrid progeny, the resulting plant was named F. hybrida Ziyi. Subsequently, comparative tests at multiple locations were conducted to examine the adaptability for cultivation and yield of seed bulbs and cut flowers of the newly bred variety.
    Result The upper perianth of Ziyi was brilliant purple (RHS: N87C), and the throat light yellow(RHS: 6D)in color. Planted from late September to early October, it bloomed 35-40d from late February to early March in the following year. On average, the leaves on the plants were 37.34cm long, the flower stems 38.66cm long with 3-4 branches on each, the main inflorescence 8.75cm with 9.56 main inflorescence florets, and the flower diameter 4.31cm with a reproduction coefficient of 5.5-6.5. In trial cultivations at 3 localities, it showed consistent and stable coloration, floral pattern, and productions per 667m2 of 24,600 commercial flowering bulbs and 53,900 cut flowers.
    Conclusion The new Ziyi freesia had an exquisite purple color with stable floral traits, highly adaptable for cultivation, and applicable for landscaping. Thus, it could be commercially cultivated in Fuzhou, as well as areas of similar climate.
