烟草杂种优势明显,繁殖系数高,去雄授粉简单易行,制种成本低,效率高。在生产上利用烟草杂种一代优势,有显著的增产增质作用。1971年,在风阳县楼店公社东方生产队试种3亩杂交烟,每亩产值比当地品种增加44％。1972年扩大到6个生产队近50亩,每亩产值比当地品种增加27—55％。根据过去搞杂交烟的经验教训,必须注意以下两个问题:
Obvious advantages of tobacco hybrids, high reproductive coefficient, easy to pollination to go male, seed production costs low, high efficiency. In the production of the advantages of using tobacco hybrid generation, a significant role in increasing production and increasing quality. In 1971, the Oriental Production Team of the commune commune in Fengyang County experimented with 3 mu of hybrid tobacco. The output value per mu was 44% more than that of the local breed. In 1972, it expanded to nearly 50 acres of 6 production teams, increasing the output value per acre by 27-55% over the local varieties. Based on the past experience of hybrid tobacco, we must pay attention to the following two issues:
