    Abstract:

    Volatiles of four loquat cultivars, Xiangtian, Jiefangzhong, Xiangzhong No.11 (Xiangtian♀×Jiefangzhong♂) and Zhongxiang No.25 (Jiefangzhong♀×Xiangtian♂) were evaluated by HS-SPME-GC-MS. Results showed that 91 aromatic volatile compounds in 11 categories were detected, in which terpenoids D-Limonene was the highest, accounted for 62.59%-68.32%, aldehydes were the next, accounted for 12.53%-18.15%. Sixty two components of volatile in Xiangtian were detected, in Jiefangzhong only 44 components. The volatile quantities in Xiangzhong No.11 and Zhongxiang No.25 were between in their parents. The common aromatic components present in both Xiangtian and its hybrid progeny were 38 and 36 kinds, respectively, whereas in Jiefangzhong and its hybrid progeny were 27 and 26 kinds of components, indicating that most of aroma compounds in offsprings were inherited from Xiangtian. The main aroma components were D-limonene, (E)-2-hexenal, , octanal, hexanal, benzenemethanol, .alpha.-methyl-, acetate, butanoic acid, 2-methyl-, methylester, allyl heptanoate and butanoic acid, 2-methyl-, ethyl ester. And the reason of Jiefangzhong has no significant aromatic volatiles were discussed.
