Abstract:

The Malaysia No.1, XYS17, XYS18 and Liulianmi jackfruit accessions were used as materials to evaluate the difference of characteristic aroma compounds. The aromatic profile of different genotypes can provide a theoretical foundation for future breeding program. Headspace solid-phase microextraction and gas chromatography-mass spectrometry (GC-MS) were used to analyze the aromatic profile of different jackfruit accessions. Sixty-six aroma compounds were identified in the jackfruit accessions. These four genotypes shared 9 aromatic substances, and showed significant difference in the relative contents, such as 3-methyl-1-butanol, dodecanal, 2-methylbutyl isovalerate, isoamyl acetate, and propyl isovalerate. Malaysia No.1 was characterized by high contents of n-amyl isovalerate, and esters (benzyl acetate), butyl acetate, isoamyl acetate, isobutyl isovalerate, and 2-methylbutyl isovalerate, XYS17 has high contents of isobutyl isovalerate, 2-methylbutyl isovalerate, n-amyl isovalerate, octyl acetate, and decanal, XYS18 has high contents of ethyl isovalerate, butyl isovalerate, ethyl butyrate, methyl isovalerate, and octanal, Liulianmi accession has exhibited contents of 3-methyl-1-butanol, 2-methyl-1butanol, 2-methylbutyl isovalerate, ethyl isovalerate, and 3-methylbutyl 3-methylbutanoate. These results will provide reference for breeding of new verities and exploiting of outstanding jackfruit germplasm in the future.

Key words: jackfruit (Artocarpus heterophyllus), germplasm, aroma compositions, aroma analysis
