Studies On The Adaptability Of New Varieties Of Flue-Cured Tobacco In Nanyang Tobacco Area Of Henan Province

7tobacco varieties, including Y101, LJ237, CF222Youxuan1, LY0414, Y8190and0408, were compared through field experiment in Nanyang tobacco planting areas. The agronomic traits, economic traits, disease resistance, appearance quality, smoking quality and the physical and chemical indicators of different varieties were investigated. And a field demonstration test for the new variety0408was conducted. The main results were as follows:1. Im2007, the results showed that, the0408’s growth period, number of leaves, plant height, stem girth, and the comprehensive economic traits were significantly better than other varieties. It has strongest disease resistance, and can be a large demonstration in the local area. The overall performances of Y101and Y8190were next only to0408, with stronger resistance, and can be used as alternatives; The CF222had the worst performance.2. The maturity of the0408is good, it has a strong gloss, sufficient oil content, better comprehensive appearance quality, good and fullness smell, good combustibility and low irritation, comfortable aftertaste, moderate physical and chemical indicators, meet the needs of China’s cigarette industry better, followed by Y101, Y8190, the comprehensive performance of the Y101,Y8190were only bext to0408.3. The results,from large-scale demonstration test of0408in Nan Yang in2012, showed that the growth potential in field, the appearance qualities after curing, and the economic traits of0408were better than the control variety NC89under different ecological conditions.In general,0408can be properly populized in Nanyang region, the Y101and the Y8190as a back-up varieties need to be tested further.
