Embodiment 1
[0014] Determine the planting quality of parental tobacco plants according to the number of seed production. Generally, the planting density of the planting field is 1100-1300 plants / mu, and the ratio of parental tobacco plants is 1:2-4. The pollen of the male parent is collected at the full flowering stage and transferred to the female parent. On the stigma of the flowers, harvest the seeds when 80% of the capsules of the female inflorescence turn yellow or light brown, pick off the whole inflorescence and hang it in the air-seeding room for post-ripening, and after the seeds are dry, they are threshed to obtain the male sterile hybrid combination YK1085 Seed.
[0015] Using YA17-1 as the male parent and MSYB55 as the female parent, a male sterile hybrid combination YK1085 was prepared. Among them, YA17-1 belongs to Dicotyledonae, Picofloweres, Solanaceae, Nicotiana and Common Nicotiana in plant taxonomy. In plant taxonomy, MSK326 belongs to Dicotyledonae, Tubeflowers, Solan...
Embodiment 2
[0017] The average value of the first-generation male sterile hybrid combination YK1085 in the 2-year production area from 2013 to 2014 was measured. The yield of YK1085 mu was 186.04 kg, which was 28.73% higher than that of the control K326. The average price was 20.38 yuan / kg, which was 10.49% higher than that of the control K326. The average output value per mu was 3889.53 yuan, an increase of 44.04% compared with the control, the proportion of top-grade tobacco was 42.2%, an increase of 46.69% compared with the control, and the proportion of upper-medium tobacco was 76.7%, an increase of 10.26% compared with the control. Please refer to Table 1 for details.

Embodiment 3
[0021] The botanical traits and main agronomic traits of the obtained male sterile hybrid combination YK1085 were tested in the three-year production area from 2011 to 2013. YK1085 grows neatly and vigorously in the field. The plant is cylindrical, the leaves are oblong, and the main veins are medium in thickness. The leaves are thicker, the leaf surface is wrinkled, the leaves are set evenly, the angle of the stems and leaves is medium, the upper leaves open well, the layers fall yellow, and it is easy to bake. In the 2013-2014 test, the average plant height of YK1085 was 109.2cm, the pitch was 5.75cm, the number of leaves was 18.47, the leaf length was 78.9cm, and the leaf width was 26.43cm. Please refer to Table 2 for details.
