Comparison And Analysis Of Flue-cured Tobacco Varieties In Baoqing

Baoqing County,Heilongjiang tobacco smoke contradiction single plant varieties,cultivars degradation industrial enterprises to provide high-quality raw materials,screening out tobacco Baoqing area screened by fine breed new varieties experiment and explore appropriate cultivation technical measures.2014 tobacco-growing areas in Heilongjiang Province Baoqing nine varieties comparison test,tested nine Longjiang tobacco varieties to 981(for the control variety),flue-cured tobacco variety Longjiang 911,PVH2254,0408,0206-41,0110-142,Longjiang 982,Yunyan 97,Hongda,comprehensive comparison of the tested botanical characters,economic characters,disease resistance,quality appearance and internal quality varieties were analyzed.The results show that:The growth period of 9 varieties was about 116 days.Longjiang 981 has good appearance,good growth potential,good smell and resistance to wildfires.However,the anti-climate spot disease and virus disease are poor and the economic benefits are not high.Longjiang 911 had good growth,strong adaptability,balanced chemical composition,good sensory evaluation,anti-climate spot and bacterial wilt.However,resistance to wildfires and brown spot disease is poor,the economic benefits are low.PVH2254 growth potential is good,sensory evaluation of the quality of smoking is good,anti-brown spot disease,black shank disease,wildfire disease and bacterial wilt.But the ability of anti-virus disease and climate spot disease is poor,the general economic benefits.Longjiang 982 has good appearance,good sensory evaluation,high economic benefit,resistance to brown spot,bacterial wilt and wildfires,but poor antiviral ability.0408 and 0110-142 had strong growth vigor,and the field growth was neat;the diseases occurred less,and the integrated disease index was the lowest compared with other tested varieties;0110-142 had the best comprehensive economic traits,0408 comprehensive economic characters were better,And the other varieties were weaker than those of the control.The chemical composition was more harmonious and the practicability was strong.The chemical composition of the former varieties was lower than that of the control..The results of industrial preference analysis showed that the cosine of 0110-142 was the largest and slightly higher than that of the control.The angle cosine of 0408 was the closest to the control,which proved that the chemical index of tobacco in Heilongjiang Province The most close.According to this study,the tested varieties in the local situation and overall performance,and think 0110-142 0408 best overall performance,integrated control characters close to or better than the control,more in line with demand for raw materials in Heilongjiang tobacco companies,so 0110-142 and 0408 should further demonstration for rational distribution and upgrading of flue-cured tobacco varieties Baoqing provide a scientific basis and reference.
