不同基因型烤烟在江西烟区的适应性研究

Adaptability of different flue-cured tobacco genotypes in Jiangxi province

为筛选适合江西烟区生态条件的优质烤烟新品种(系),引进CC27、FJ209、20810、中烟204、F31-2、NX0914等6个烤烟品种(系),以K326为对照,试验分析各品种(系)的生育期、农艺性状、抗病性、经济性状、外观质量、化学成分和感官品质。结果表明:各参试品种(系)生育期与对照相近,其中20810经济性状较好,上等烟比例高,感官质量中等;中烟204田间生长势强,综合抗病性好,产值产量高,感官质量仅次于K326;NX0914产值产量显著优于K326,中上等烟比例较高,感官质量优于K326;其他参试品种综合表现一般。20810、中烟204和NX0914可扩大种植面积,进一步验证研究。

The growth period,agronomic characters,economic characters,disease resistance,appearance quality,chemical composition and sensory quality of seven flue-cured tobacco varieties(lines),named CC27,FJ209,20810,Zhongyan 204,F31-2,NX0914 and K326(CK),were analyzed by a field test in Jiangxi province to screen high quality varieties.The results showed that the growth period of all testing varieties(lines)was similar to K326.20810 showed better economic characters,higher ratio of high quality leaf and mid-level sensory quality.The sensory quality of Zhongyan 204 with strong growth potential in the field,better comprehensive disease resistance and high production yield was second only to K326.The production and output value,high middle class leaf and sensory quality of NX0914 were significantly better than that of K326.The others were generally.So we suggest 20810,Zhongyan 204 and NX0914 could be enlarged planting areas and got further validation studies.
