After repeated pollination and post-hybridization GA40 PPM for about a week, the flue-cured tobacco and sorghum, flue-cured tobacco and Corn, flue-cured tobacco and Datura hybrids. Twenty-eight hybrid combinations were made in seven or eight years, and 17 combinations were successfully obtained after hybridization. The total number of hybrids 87, after hybridization shed 35 flowers. The number of hybrid flowers 775, the capsule has 271
