为筛选出优质的烤烟品种在生产上推广应用,解决黑龙江烟区品种单一的问题,以NC89为对照,对7个新引进的美国和巴西品种进行了田间比较试验。结果表明:(1)PVH2310成熟早,抗病性强,综合经济性状、原烟外观质量最好,产量、产值、均价、上等烟比例最高,与对照品种NC89相比,烟叶产量提高5.41%,产值提高25.08%,均价提高24.16%,上等烟比例提高13.25个百分点,是一个产量、品质、抗性、适应性等重要性状间较为谐调兼顾的优良品种。(2)NC-YATAS-2综合经济性状和外观质量与对照NC89相当。
In order to screen out high-quality flue-cured tobacco varieties in the production of popularization and application, to solve the single variety of tobacco varieties in Heilongjiang Province to NC89 as a control, seven newly introduced varieties of the United States and Brazil were field trials. The results showed that: (1) PVH2310 had the characteristics of early maturity, strong disease resistance, comprehensive economic traits, the best appearance quality of raw tobacco, the highest yield, the output value, the average price and the finest tobacco. Compared with NC89, the yield of tobacco increased by 5.41 %, The output value increased by 25.08%, the average price increased by 24.16% and the proportion of top-grade tobacco increased by 13.25%. It is a fine variety with more harmonization between important traits such as yield, quality, resistance and adaptability. (2) NC-YATAS-2 comprehensive economic traits and appearance quality and control NC89 quite.
