摘要：

为筛选出鄂东大别山区油茶优良种质资源,对位于鄂东大别山区黄冈市红安县、麻城市、蕲春县的28株油茶实生单株进行调查,测定分析不同单株的冠幅产量、单果重、果纵径、果横径、果形指数、鲜出籽率、干出籽率、种仁含油率以及脂肪酸成分等性状指标,选取冠幅产量、单果重、干出籽率、种仁含油率、油酸、亚油酸等12个主要经济性状指标进行模糊综合评价。结合油茶品种选育技术的相关标准筛选出HQ-3、MF-46和QY-105 3个油茶实生单株,其平均隶属度分别为0.82693、0.80718和0.80524,高于其他单株。通过模糊综合评价筛选出的3个油茶优良单株4年平均冠幅产量、鲜出籽率、种仁含油率、油酸、亚油酸含量等指标均达到国家标准《油茶优良品种选育技术》的要求,宜作为优良单株开发利用。

Abstract:

To screen the superior germplasms of Camellia oleifera at the Dabie Mountain of eastern Hubei, an investigation of 28 individuals of C. oleifera seedlings was conducted in Hong’an, Macheng, Qichun of Hubei. Main economic characters such as crown yield, single fruit weight, fruit diameter, fruit shape index, the ratio of seed to fresh fruit, the ratio of dry seed to fresh fruit, the oil rate of dry kernel and fatty acid composition were determined and analyzed. 12 major economic characters such as crown yield, single fruit weight, the ratio of dry seed to fresh fruit, the oil rate of dry kernel, oleic acid, linoleic acid were selected for fuzzy comprehensive evaluation. According to relevant standards of breeding techniques of C. oleifera, HQ-3, MF-46 and QY-105 were screened as superior individuals, whose average membership degree was 0.82639, 0.80718, and 0.80524, respectively, higher than that of other individuals. The crown yield, the ratio of seed to fresh fruit, the oil rate of dry kernel, oleic acid and linoleic acid content of the three individuals all met the requirements of the national standard Oil Tea Excellent Variety Breeding Technology, and could be developed and utilized as superior individuals.

Key words: Camellia oleifera, superior individual, economic character, average value of membership, fuzzy comprehensive evaluation
