福建10个茶树杂交创新种质初步鉴定

对10个茶树杂交创新种质形态特征和生物学特性、生化成分、乌龙茶制茶品质、遗传相似性进行初步鉴定，结果表明：①参试种质为灌木型或小乔木型，树姿直立或半开张，中叶类。发芽密度中或密，1芽2叶生育期在3月中旬至下旬，芽叶色泽有黄绿色、紫绿色、紫红色3种类型，茸毛少。叶片大小为中叶，叶型有卵圆、椭圆、长椭圆3种类型，叶质均柔软。②参试种质间1芽3叶长、1芽3叶百芽重、花冠直径、花瓣个数、果实大小、种径大小均无显著差异。③参试种质生化分析样品水分、水浸出物、氨基酸、咖啡碱、茶多酚、酚氨比均无显著差异。④FT104、FT516、FT528乌龙茶加工品质优，可作为育种材料利用。⑤在遗传相似系数为0．53处可将参试种质分为4类，其中 FT102和 FT516为第1类，FT1031为第2类，FT1032为第3类，其他7个种质为第4类。

Preliminary Identification of 10 Tea Hybridization Germplasms in Fujian Province

The morphological and biological characteristics,biochemical composition,Oolong Tea quality,genetic similarity of 10 tea hybridized germplasms were character.Our results showed that：①The tree model are shrub or small tree,and the tree pose are erect or semi opened;the bud germinated moderately or densely,a bud and two leaves growth begins in the middle to late March,and there are 3 color types on bud and leaves：yellow green, purple green,purple,and less hair on leaves;All tested germplasms are middle leaves,and there are 3 leaves types：oval,elliptical,long elliptic;Leaves matter is soft.②There have no significant differences in the length of a bud and three leaves,the 100 buds weight of a bud and three leaves,the flower diameter,the flower number,the fruit size and the seed size.③ There have no significant differences in moisture content,water extracts,amino acids,caffeine,tea polyphenols,phenol ammonia ratio.④ FT104,FT516,FT528 could be priority used as breeding materials as their excellent Oolong Tea quality.⑤The tested germplasms could be divided into 4 types in genetic similarity coefficient of 0.53,the first class included FT102 and FT516,the second class is FT1031,the third class is FT1032,the fourth class included the other 7 germplasms.
