摘要
[目的]为筛选出适宜许昌烟区种植的浓香型烤烟新品种。[方法]以NC89为对照,对6个烤烟品种CF213、中烟202、秦烟97、豫烟9号、辽烟17、龙江935的生物学性状、外观质量和经济性状进行比较分析,并对农艺性状与经济性状的关系进行多元分析。[结果]豫烟9号和龙江935的田间长势强,产量、产值高,抗病性强,外观质量好,可以在许昌烟区进一步示范验证;CF213和中烟202的田间抗病性差,尤其抗病毒病能力比对照差,CF213的产量和产值均比对照低;秦烟97与辽烟17的经济性状差,辽烟17抗病性差(感黑胫病)。产量与株高、叶数和径围之间呈极显著中度正相关;株高和径围对产量及产值的影响主要为直接作用,叶数对产量和产值的影响主要为间接作用。[结论]该研究可为许昌烟区烤烟品种的更新换代及生产推广提供科学依据。
[ Objective] The purpose was to select the best tobacco varieties for planning in Xuchang tobacco area. [ Method] By contrast with NC89, the biological characteristics, leaf appearance qualities and economic characters of six tobacco variety, including CF213, zhongy- an202, qinyan97, yuyan9, liaoyanl7 and longjiang935 were analyzed. The correlations between agronomic characters and economic characters were analyze by multivariate analysis. [ Method] The results showed that CF213 and zhongyan202 had great growth, such as strong growth vig- or in fields, high yield and output, strong disease resistance, good apparent quality. They should be recommended for future planting in Xuchang. CF213 and zhongyan202 had poor field resistance, especially the antiviral ability compared with the treatment of CK. The yield and value of CF213 were lower than control. The economic characters and disease resistance of qinyan97 and 980 were poor. The resistance to Black Shank of liaoyanl7 was low. Yield and height have significantly middle positive relation with the plant height, leaf number and girth. The plant height and girth directly affected yield and output. The effect between leaf number and yield and output was mainly indirect. [ Con- clusion ] The study provides a scientific basis for updating, producing and popularizing of flue-cured tobacco new varieties in Xuchang tobacco area.
