【摘要】 试验表明当前推广的红花大金元和 K₃₂₆产量、产值、均价、上等烟率均超过5个新引进品种（系）,结果经方差分析均有显著差异。轻感花叶病的有 K₃₂₆、RG₁₁;感赤星病的有红花大金元、K₃₂₆。综述其各品种经济性状仍以红花大金元为主栽品种,辅以一定面积的 K₃₂₆等品种为宜。更多还原

【Abstract】 The experiment has indicated that the popularized tobacco vsrieties,safflower gold dollar and K₃₂₆ have higher yields and output values,even prices and top-qualities than those of the 5 varieties which were newly introduced.There are significant differences in their variance analyses.The varieties infected by mosaic virus are K₃₂₆ and RG₁₁,and the varieties infected by barn rot are safflower gold dollar and K₃₂₆.To sum up the economic characteristics of all varieties,it is believed that safflower gold dollar is still the chief planting variety,and K₃₂₆ can also be planted as asupplement.更多还原
