    Abstract:

    Improving the fragrance characteristics through hybridization is an important way of fragrant flower breeding. In this study， Headspace-Solid Phase Microextraction-Gas Chromatography-Mass Spectrometry （HS-SPME-GC-MS） was employed to determine the volatile organic compounds （VOCs） in blooming petals of the rose variety Mantingfanghua and its parents. Comparison analysis of VOCs showed that 25， 36 and 22 VOCs were identified in the blooming petals of Mantingfanghua， its paternal species Rosa beggeriana Schrenk and maternal variety Queen Elizabeth， respectively. The totally identified 59 components can be sorted to 8 major compounds based on their chemical structures， including alcohols， terpenes， esters， hydrocarbons， ethers， aldehydes， ketones and acids. Mantingfanghua has 10 components in common with Rosa beggeriana Schrenk， while 13 in common with Queen Elizabeth； Mantingfanghua has the VOCs composition in higher similarity to its maternal variety. The total VOCs content in Mantingfanghua was 579.70 ng/g， which was lower than that in its paternal species （13939.42 ng/g） and its maternal variety （1157.10 ng/g）. The contents of terpenoids and benzenoids/phenylpropanoids were lower in Mantingfanghua than those in its parents； in opposite， the contents of sesquiterpenoids in Mantingfanghua were higher than those in its parents. Meanwhile， the content of fatty acid derivatives in Mantingfanghua fell in between those in their parents. Principal component analysis showed that the β-Cubebene， β-Cadinene， β-Caryophyllene were the main VOCs that may affect the fragrance from Mantingfanghua. This study provides insights for the genetic improvement of rose floral fragrance metabolism， which has important value for both theoretical and practical purpose.
