Screening test of flue-cured tobacco varieties(lines)in Zhucheng tobacco-growing area
To select new flue-cured tobacco varieties suitable for planting in Zhucheng tobacco-growing area of Shandong Province,9 varieties(lines)such as QY2329,YY021 and HB0901 were compared with NC89 as the conventional control and Zhongyan100 as the secondary control,and their growth period,botanical traits,agronomic traits,disease resistance,and economic traits were determined.The results showed that the growth period of 11 varieties(lines)was 130-140 days.In terms of botanical traits,the field growth of HB0901 was uneven,and the field growth of other varieties(lines)were relatively uniform or neat,YY021,LY2804,CF241,HB056,Longjiang 0110 and LY716-2 grew strongly during the whole growth period.In terms of agronomic traits,the plant height of each variety(lines)was 118.5-162.8 cm,the number of leaves was 20.0-29.3,the spacing was 2.9-4.8 cm,the stem circumference was 9.9-11.4 cm,the waist leaf length was 61.6-72.8 cm,and the waist leaf width was 30.1-39.8 cm.In terms of disease resistance,the main diseases were black shank disease,horn spot/wildfire disease and viral disease.In terms of economic traits,the yield of all varieties(lines)was 2 141.70-2 795.10 kg/hm2,which was higher than that of the control NC89,the yield of HB0901,CF241,YM2020,Longjiang 0110,and LY716-2 was higher than that of Zhongyan 100,CF241 had the best performance in economic traits,with an average price of 31.32 yuan and an output value of 85 672.73 yuan/hm2,and the proportion of medium tobacco was 96.45%.According to the overall field growth and output value,CF241 plant type was medium,the growth period was moderate,the stratified yellowing was obvious,the field growth and disease resistance were strong,the economic characteristics were prominent,and the comprehensive performance was the best.In addition,HB0901 and Longjiang 0110 plant type medium,stratified yellow,strong disease resistance,excellent performance of economic traits,LY716-2 plant type tall,strong disease resistance and excellent performance of economic traits.In summary,4 varieties(lines)including CF241,HB0901,Longjiang 0110,and LY716-2 were suitable for further trial planting in Zhucheng tobacco-growing area.
