Abstract:Newly-introduced and early maturity tobacco variety of PVH19 was tested at 16 places. The results are as follow: PVH19 grow rather uniformly in the field with tower shapes; The been topped plant height of PVH19 is 107.5 cm with 19.7 harvestable leaves; The leaf is in ellipse shape with moderate angle between leaf and stalk, and with moderate to strong leaf midrib; The yield is similar to the yield of K326, and average days needed for staying in the field from being transplanted to being harvested is 111.9 d, shorter 11 days than K326; PVH19 is resistant to the TMV, moderately resistant to the black shank and brown spot; The flue-cured leaves are yellow with most in orange color, the luster of the cured leaves is moderate to strong with moderate oil and loose structure, and the leaf is in moderate to thin thickness, and is good in quality. It indicated that tobacco variety of PVH19 is early maturity, wide adaptability, rich comprehensive resistance to diseases, high quality and appropriate yield.
Keywords:Introduction test   Early maturity tobacco variety   PVH19
