Abstract:

Currently,tobacco variety breeding primarily focuses on macro-level aspects such as agronomic traits,whereas the flavor characteristics of cigar tobacco leaves depend on the accumulation levels of metabolites during the early growth stage and their subsequent transformation during post-harvest processing. Therefore,breeding cigar tobacco varieties with abundant metabolite accumulation and superior agronomic traits is of paramount importance. This study employed derivatized gas chromatography-mass spectrometry (GC-MS) and headspace-solid phase microextraction-gas chromatography-mass spectrometry(HS-SPME-GC-MS)techniques to analyze major agronomic traits and detect volatile and aroma-contributing metabolites in nine cigar tobacco varieties cultivated in Xuancheng,Anhui Province. Differential metabolites were identified for subsequent metabolic pathway analysis. The results demonstrated that T11 exhibited the best agronomic traits. Metabolic profiling revealed that 63.0% of differential metabolites were upregulated in T11,with these upregulated metabolites correlating positively with tobacco aroma,flavor profile,and smoking quality. In summary,T11 not only demonstrates outstanding agronomic characteristics but also possesses a richer repertoire of beneficial metabolites,indicating its potential for developing high-yield and premium-quality cigar tobacco varieties.
