In three Camellia vietnamensis producing areas of southwest tropical rainforest in Hainan Province, Baomeiling Ecological Protection Reserve (JB), Bawangling Gibbon Reserve (QS), and Jiangpai Village (XS), Baisha Li Autonomous County, 22 high-yielding single strains were selected, for primary screening and comparison. Observe fruit yield per unit area, oil content rate of fresh fruit, grude oil yield per unit of crown area, peroxide value, iodine value, acid value, saponification value and the contents of palmitic acid, stearic acid, oleic acid, linoleic acid, myristic acid, palmitoleic acid, linolenic acid, arachidic acid, eiconsenoic acid in seed oil for 3 years, after the data was treated with the methods of ANOVA, gray association analysis, and cluster analysis, then screen out the more superior single strains. There existed significant difference in grude oil yield per unit of crown area, oil content rate of fresh fruit and fruit yield per unit area, among them, fruit yield per unit area might be the key indicator of high-yield screening. The physicochemical nature and fatty acid content of camellia seed oil both meet the requirements of "oil-tea camellia seed oil" (GB/T 11765—2018), but there existed some significant difference in some indicators, and there existed the linear correlations between some saturated and unsaturated fatty acids, then there existed the phenomena of the saturated acids changed into unsaturated acids, indicating that the camellia seed oil has no quality problems, and the different tree had its specific characteristic, so the breeding target should be mainly high yield and stable yield, and iodine value, saponification value and the contents of oleic acid might be the effective indicators for selection. Known from the grey association analysis data, the single strains with superior integrated traits were successively JB2, JB7, QS6, JB1, QS5, XS2, JB4, XS4, JB9 and XS5 respectively; Known from the clustering results, it is better to gather all the individual strains into 9 categories (r=0.904), among them, the top seven single strains of comprehensive traits were clustered in Ⅰ, Ⅸ,Ⅶ and Ⅵ respectively, indicating it was expected to screen out the characteristic diverse varieties. JB2, JB7, QS5, XS2 and XS4 belonged to the expected individual strains whose comprehensive behaviors in economic traits were excellent, and JB2 among them was the best one and rare.

在海南省保梅岭生态保护区(JB)、霸王岭长臂猿保护区(QS)、白沙黎族自治县细水乡江排村(XS)等琼西南热带雨林越南油茶产区选出22株丰产单株,开展初选比较试验。连续3 a观测单位冠幅面积果实产量、鲜果含油率、单位冠幅面积毛油产量、过氧化值、碘值、酸价、皂化值和棕榈酸、硬脂酸、油酸、亚油酸、肉豆蔻酸、棕榈油酸、亚麻酸、花生酸、花生一烯酸等含量,经过方差分析、灰色关联分析和聚类分析,以期筛选出供复选的单株。不同丰产单株的单位冠幅面积果实产量、鲜果含油率、单位冠幅面积毛油产量效率都存在显著差异,其中单位冠幅面积果实产量可能是丰产性选择的关键指标;茶籽油理化性质和脂肪酸含量均符合《油茶籽油》(GB/T 11765—2018)的要求,但不同产区的不同单株茶籽油理化性质和脂肪酸组成存在差异,某些饱和与不饱和脂肪酸含量间存在线性相关性,存在由饱和向不饱和转化的现象,说明琼西南热带雨林产区的茶籽油无品质问题,同时各有特色,育种目标应以丰产性和稳产性为主,并且茶籽油碘值、皂化值和油酸含量可能是油茶品质育种的有效选择指标;综合性状较优的单株依次为JB2、JB7、QS6、JB1、QS5、XS2、JB4、XS4、JB9、XS5,全部供试单株聚成9类(r=0.904)效果较好,其中,综合性状排名前7的单株分别聚在了Ⅰ、Ⅸ、Ⅶ、Ⅵ类,表明越南油茶经实生选种有望筛选出特点多样化的品种,并且JB2、JB7、QS5、XS2和XS4是综合表现优异的5个单株,其中JB2最优,可能是稀有基因型。

在海南省保梅岭生态保护区(JB)、霸王岭长臂猿保护区(QS)、白沙黎族自治县细水乡江排村(XS)等琼西南热带雨林越南油茶产区选出22株丰产单株,开展初选比较试验。连续3 a观测单位冠幅面积果实产量、鲜果含油率、单位冠幅面积毛油产量、过氧化值、碘值、酸价、皂化值和棕榈酸、硬脂酸、油酸、亚油酸、肉豆蔻酸、棕榈油酸、亚麻酸、花生酸、花生一烯酸等含量,经过方差分析、灰色关联分析和聚类分析,以期筛选出供复选的单株。不同丰产单株的单位冠幅面积果实产量、鲜果含油率、单位冠幅面积毛油产量效率都存在显著差异,其中单位冠幅面积果实产量可能是丰产性选择的关键指标;茶籽油理化性质和脂肪酸含量均符合《油茶籽油》(GB/T 11765—2018)的要求,但不同产区的不同单株茶籽油理化性质和脂肪酸组成存在差异,某些饱和与不饱和脂肪酸含量间存在线性相关性,存在由饱和向不饱和转化的现象,说明琼西南热带雨林产区的茶籽油无品质问题,同时各有特色,育种目标应以丰产性和稳产性为主,并且茶籽油碘值、皂化值和油酸含量可能是油茶品质育种的有效选择指标;综合性状较优的单株依次为JB2、JB7、QS6、JB1、QS5、XS2、JB4、XS4、JB9、XS5,全部供试单株聚成9类(r=0.904)效果较好,其中,综合性状排名前7的单株分别聚在了Ⅰ、Ⅸ、Ⅶ、Ⅵ类,表明越南油茶经实生选种有望筛选出特点多样化的品种,并且JB2、JB7、QS5、XS2和XS4是综合表现优异的5个单株,其中JB2最优,可能是稀有基因型。

In three Camellia vietnamensis producing areas of southwest tropical rainforest in Hainan Province, Baomeiling Ecological Protection Reserve (JB), Bawangling Gibbon Reserve (QS), and Jiangpai Village (XS), Baisha Li Autonomous County, 22 high-yielding single strains were selected, for primary screening and comparison. Observe fruit yield per unit area, oil content rate of fresh fruit, grude oil yield per unit of crown area, peroxide value, iodine value, acid value, saponification value and the contents of palmitic acid, stearic acid, oleic acid, linoleic acid, myristic acid, palmitoleic acid, linolenic acid, arachidic acid, eiconsenoic acid in seed oil for 3 years, after the data was treated with the methods of ANOVA, gray association analysis, and cluster analysis, then screen out the more superior single strains. There existed significant difference in grude oil yield per unit of crown area, oil content rate of fresh fruit and fruit yield per unit area, among them, fruit yield per unit area might be the key indicator of high-yield screening. The physicochemical nature and fatty acid content of camellia seed oil both meet the requirements of "oil-tea camellia seed oil" (GB/T 11765—2018), but there existed some significant difference in some indicators, and there existed the linear correlations between some saturated and unsaturated fatty acids, then there existed the phenomena of the saturated acids changed into unsaturated acids, indicating that the camellia seed oil has no quality problems, and the different tree had its specific characteristic, so the breeding target should be mainly high yield and stable yield, and iodine value, saponification value and the contents of oleic acid might be the effective indicators for selection. Known from the grey association analysis data, the single strains with superior integrated traits were successively JB2, JB7, QS6, JB1, QS5, XS2, JB4, XS4, JB9 and XS5 respectively; Known from the clustering results, it is better to gather all the individual strains into 9 categories (r=0.904), among them, the top seven single strains of comprehensive traits were clustered in Ⅰ, Ⅸ,Ⅶ and Ⅵ respectively, indicating it was expected to screen out the characteristic diverse varieties. JB2, JB7, QS5, XS2 and XS4 belonged to the expected individual strains whose comprehensive behaviors in economic traits were excellent, and JB2 among them was the best one and rare.
