Study On Oriented Flue-cured Tobacco Varieties Based On The "Nanjing" Brand In Pu ’er Area

In order to extract flue-cured tobacco varieties to meet the raw material requirements of "Nanjing" cigarette and give full play to the region of the ecological resources in Pu’er area and show the features of Pu’er area leaf tobacco quality style. Four varieties comparison experiment was carried out in Ning’er county and Mojiang county in2011. Separately from the main growth period botany characters, appearance quality, economic characters, chemical composition and its coordination, sensory quality evaluation of KRK26,yunyan97, K326and yunyan87four kinds of flue-cured tobacco varieties. The four flue-cured tobacco varieties screening combined with Jiangsu zhongyan "Nanjing" cigarette brand material requirement in Pu’er area. The results showed that:Different species into the growth period (except KRK26late) have almost the same time, environment on both greater effects on the growth period, the agronomic traits of experimental varieties. All the varieties in yield and output value, average price, the proportion of superior tobacco, significant differences in the proportion of superior tobacco, MoJiang Jingxing yunyan87and Ning’er Mengxia K326has bigger advantage in economic characters.On the appearance quality performance in different regions of the varieties are inconsistent, Ning’er yunyan97and Mojiang yunyan87has good performances, KRK26has poor performance. The central tobacco leaves chemical indicators on the whole tobacco scored higher than the upper and lower tobacco leaves, Ning’er Mengxian KRK26, yunyan97and Mojiang Jingxing yunyan87, yunyan97has higher scores. The sensory quality of Ning’er Mengxian yunyan87, yunyan97and Mojiang Jingxing KRK26, yunyan87has higher scores. Comprehensive quality of Ning’er Mengxia yunyan97and Mojiang Jingxing yunyan87has the highest score.Considering factors such as economy and quality, Mojiang base planting yunyan87, Ninger base planting yunyan97can meet most of Jiangsu ZhongYan "Nanjing" brand of the raw material requirements.
