“Zhongyan 15” new breed in 1976 with single-2 as the female parent, Speight G-28 as a male parent, was bred in 1984. After two years of 1982-1983 varieties of comparative test, 1983-1984 two years of regional trials in Shandong Province, 1984 Huanghuai tobacco varieties regional test and Heilongjiang Province, Sichuan Province varieties comparison test, the average yield 366.03 pounds, the average price of 0.9690 yuan, on the 77.42% of middle-grade tobacco leaves, with an output value of 354.68 yuan per mu. The average price increased by 11.83% and 10.11% respectively over the control varieties Speight G-140 and Panyuanhuang, with the average price increasing by 11.83% and 10.11% respectively. The upper middle-grade tobacco increased by 13.16% and 18.80%, the output value per mu increased by 84.61 yuan and 52.49 yuan respectively, 31.33% and 15.54% respectively; the proportion of middle-yellow tobacco increased significantly, while that of green tobacco decreased below 1.9%. Large-scale production demonstration, the average per mu yield of 390.6 kg, the average price of 1.015 yuan, 396.46 yuan per mu, finest 4.99% tobacco, tobacco, 80.58% of the middle rate, only 3.46% of the smoke. Compared with the cultivated varieties Panyuanhuang and G-140, the average yield per mu was 64.5 kg and the average price was 0.1335 yuan, up 15.14%. The yield on mu increased 107.97 yuan and increased 37.43%. In 1984, the planting area in Shandong, Hubei, Heilongjiang, Sichuan and Henan Provinces was nearly 140,000 mu, which increased the economic income by about 15 million yuan. Good quality appearance of tobacco leaves, leaves after the color is yellow, still oil Run, eat pure, aroma, momentum moderate, a slight gas. Nicotine content of tobacco was 1.61%, the ratio of nicotine to alkalinity was 11.86, and the ratio of nitrogen to nitrogen was 0.94. The chemical composition was suitable and the proportion was still in harmony. Tidy field growth, genetic stability. More resistant to fertilizer, leaves fall yellow, easy baking; anti-shank. Suitable for cultivation in hills and hills with irrigation conditions.
