Evaluation of Agronomic Characters and Economic Characters for Several New Tobacco Lines
摘要
Abstract
With K326 as the check variety, the agronomic and economic characteristics of 8 new tobacco lines were com-paratively tested by field plot experiment. Results were as follows:(1) There was variability among new tobacco lines in leaf number, plant height, stem diameter and length and width of maximum leaf at 35th day after transplanting. ZYH-4 showed the most leaves, and DZ-4 was the tallest. The stem diameter of new tobacco lines was larger than that of K326, but YQ-1 and ZYH-4. Appearances with MT-2, SX-1 and ZYH-5 showed that larger at the length and width of maximum leaf than that of K326. (2) There was variability among agronomic characteristics at 60 days after the transplan-ting. MT-2 showed the most leaves, and all new tobacco lines was taller than that of K326, but YQ-1 and MT-2. WY-1 showed the most stem diameter, and the length maximum leaf of SX-1 and width of maximum Leaf of MT-1. (3) The variable a mplitude of yield among new tobacco lines are from 1 863 kg/hm2 to 3 380. 85 kg/hm2 . The MT-2 has a good colligation character at output value, yield, average price and rate of first class tobacco. (4) Cluster analysis showed that there was good colligation economic character performance lines among MT-2, DZ-3, YQ-1, SX-1 and WY-1. And MT-2 shows distinguishing advantages.关键词
