摘要
华烟06是从K326田间变异株系中选育出来的抗早花烤烟新品系。2008年在梅州烟区试种该品系,并对该品系的生育期、植物学性状、化学成分、抗病性以及经济性状进行观测分析。结果表明,华烟06的有效叶数为21.64片,产量为2 465.28 kg/hm2,明显优于云烟87,化学成分与云烟87差异不显著。华烟06具有优质高产,适应性广,抗早花能力强等优点,但上部叶糖含量、下部叶烟碱含量以及上等烟比例稍低,易感黄瓜花叶病,还需进一步改良。
A new resisting premature flowering tobacco variety Huayan 06 was selected in K326 field variants, which was cultivated in Meizhou region in 2008. Its growing time, phytological characters, chemical components, resistance to diseases and economical characters were analyzed in present study. The results show that its effective leaf number is 21.64 per plant and the yield has reached 2465.28 kg/ha, which are more than that of Yunyan 87 obviously. The differences of chemical components between the two varieties are insignificant. Huayan 06 has high quality and yield, extensive adaptability, high ability to resist premature flowering and other adversities. Nevertheless, the sugar contents of its upper leaves, nicotine contents of lower leaves and the rate of first class are low. It is also susceptible to CMV, which is necessary to study and improve it further.
