延边晒红烟杂交种延晒10号选育

延晒10号是吉林省延边农业科学院以自育的新品系B7为母本,抗病新品种延晒9号为父本杂交选育的杂交种.经多年各类试验表明,延晒10号的平均产量为2 401.63 kg/hm2,产值为23 562.49元/hm2,均价为9.81元/kg,一、二级烟率为45.63％左右.结果表明,该品种适应性较强,易晾晒,免疫TMV病毒病、抗野火病和赤星病、中抗PVY病毒病;株式塔形、叶形长椭圆、大田生育期94 d左右.烟叶成熟较集中,原烟颜色棕红色,油分多,色度强,单叶重8.22 g左右;主要化学成分含量适宜,比例协调;评吸质量较好.

Breeding and selection of a new hybrid Yanbian sun-cured red tobacco variety Yanshai10

Yanshail0, a new sun-cured variety was developed by crossing the female parent B7 bred by Yanbian Academy of Agricultural Sciences and male parent Yanshai9 with good resistance to dis- ease. The results after years of all kinds of experiments showed that Yanshail0 produced 2 401.63 kg/hm2 in average yield and 23 562.49 yuan/hm2 in average output value,and its average price was 9.81 yuan/kg, the rate of first and second grade leaves was about 45.63%. Yanshail0 re- vealed several properties of good adaptability,sun-cure easiness,TMV immunity, and resistances to tobacco wildfire disease and brown spot disease,moderate resistance to PVY. Yanshail0 was charac- terized by a turriform plant shape and long elliptical leaf shape, field grow period about 94 days. Yan- shall0 showed stronger growth vigor and tidiness, the maturation of tobacco leaves was relatively concentrated. The flue-cured leaves were brown red color, rich oil, single leaf weight was about 8.22 g. Contents of major chemical components and their ratio in leaves of Yanshai 10 were suitable, with better smoking quality.
