一、目的优良品种是优质烤烟生产的基本条件。近几年来,为了提高我国烤烟质量,有关单位陆续从国外引进了一些烤烟品种,对提高我国烤烟质量起到了推动作用,但由于良种繁育方面的问题,这些外引品种均程度不同地出现退化或混杂。为了更好地鉴定一些外引品种的特性,选择优质、适产、抗逆性强的优良品种,用于生产,1987年我所直接从美国引进了九个烤烟品种的原种,在河南省叶县、鲁山、宝丰三县进行品种比较试验。二、参试品种1.Speight G140 2.NC567
First, the purpose of fine varieties is the basic conditions for the production of high-quality flue-cured tobacco. In recent years, in order to improve the quality of flue-cured tobacco in our country, some units have successively introduced some flue-cured tobacco varieties from abroad, which have played a catalytic role in improving the quality of flue-cured tobacco in our country. However, due to the problems of thoroughbred breeding, Mixed. In order to better identify the characteristics of some exotic varieties, we selected fine varieties of high quality, moderate quality and strong resistance for production.
