    摘要:

    通过与赣南各县(区)果业主管部门合作及走访果农,在赣南进行了野生山金柑种质资源调查与收集,共收集与鉴定评价野生山金柑种质资源716份。结果表明:赣南野生山金柑分布于安远、龙南、章贡、崇义、于都、信丰等县(区);性状统计发现树姿、节间长度、刺数量、刺长度、叶片长度、叶片宽度、叶柄、叶形、翼叶、叶尖缺刻、单果重量、果面主色、果面杂色、种子数量、油胞明显度、果皮厚度16个性状存在差异,进一步基于差异性状进行聚类分析发现可分为4大类8小类;抗病性鉴定初步筛选出一批对柑橘溃疡病、碎叶病、裂皮病和衰退病具有抗性的单株。根据柑橘产业需求,筛选出无刺、无籽、大果、晚熟和抗病性植株,对山金柑新品种选育、柑橘产业发展具有较明确的利用价值。

    Abstract:

    Through cooperation with the fruit industry authorities of various counties (districts) in Gannan and visits to fruit farmers, the systematic investigation and collection of wild Fortunella Hindsii germplasm resources were carried out in Gannan, and a total of 716 wild Fortunella Hindsii germplasm resources were collected, identified and evaluated. The results showed that the Gannan Fortunella Hindsii was distributed in Anyuan, Longnan, Zhanggong, Chongyi, Yudu, Xinfeng and other counties (districts). The trait statistics showed that there were differences in tree posture, internode length, thorn number, thorn length, leaf length, leaf width, petiole, leaf shape, wing leaf, leaf tip lack of engraving, single fruit weight, fruit surface main-color, fruit surface variegation, seed number, oil cell obviousness, peel thickness 16 personality traits, and further cluster analysis based on those difference traits found that they could be divided into 4 categories and 8 subcategories. Disease resistance identification preliminarily screened a batch of single plants resistant to Citrus Bacterial Canker Disease, Citrus Tatter Leaf Virus, Citrus Exocortis Viroid and Citus Tristeza Virus. According to the needs of citrus industry, thornless, seedless, big-fruit, late-ripening and disease resistant plants were screened, which have clear utilization value for the selection and breeding of new varieties of camellis and the development of citrus industry.
