| Abstract: |
| 【Objective】The study was carried out to screen new varieties (lines) of flue-cured tobacco with high
quality adapted to ecological conditions in Ji’an tobacco production area.【Method】Five flue-cured tobacco varieties (lines)
including CC400, PVH2233, PVH2343, 1604 and Xiangyan 7 were introduced from the imported varieties and domestic
self-bred varieties, and the main conventional varieties Yunyan 87 and K326 were used as control varieties. A community
comparative trial was conducted for two consecutive years from 2019 to 2020. The growth period, agronomic traits, disease
resistance, economic characters, appearance quality, chemical composition and sensory quality of each variety (line) were analyzed.【Result】The Xiangyan 7,which showed a good balance between quality and benefit, had better color and oil content.
The output and yield of Xiangyan 7 were higher than those of Yunyan 87 by 305.85 kg/hm2 and 4 837.95 Yuan/hm2
respectively.
The sensory quality was obviously better than the main variety Yunyan 87. However, attention should be paid to the prevention
and control of common mosaic disease in field at early stage. The PVH2233 with good interannual stability and medium sensory
quality had 3-4 pieces of leaves more than the control, and the vigorous growing period was 5-7 days longer than that of the
control. It was necessary to strengthen the researches on supporting cultivation techniques. The 1604 had the advantages of early
growth and rapid development, largest pitch and lumbar leaf area, better appearance quality and economic character, and better
sensory quality than Yunyan 87. The CC400 was similar to K326 in field growth and had better leaf opening, but the occurrence
of bacterial wilt was relatively severe and the economic character was not prominent. The PVH2343 had thicker leaves, but the
incidence of climatic spot disease was more severe, and the sensory quality was slightly poor.【Conclusion】The comprehensive
performance of Xiangyan 7, PVH2233 and 1604 was better, which could be further verified by expanding the planting area. |
