4个烤烟品种在天柱县生态适应性试验

Test of Ecological Adaptability of Four Flue-cured Tobacco Varieties in Tianzhu County

为优选适应天柱县烟叶开发品种,以NC82、G28、云烟202、930032为参试品种,以云烟85和K326为对照,鉴定参试品种在当地生态条件下区域适应性及其品质差异。结果表明,各参试品种(系)生育期为120～125d,与对照K326和云烟85差异不大;农艺性状NC82在各参试品种(系)中表现最好,与对照K326相当,G28、云烟202、930032顶叶表现较差;田间自然抗病性除NC82表现低抗气候斑外,其余品种(系)均表现较强的抗病性;经济性状除NC82表现与对照K326相当外,其余品种均表现较低的经济效益;烟叶内在质量表现最好的为云烟202,感官质量表现最好的为930032品种,其余品种(系)烟叶质量与对照云烟85和K326差异不大。因此,NC82在天柱县可适度推广种植,而G28、云烟202、930032由于表现较低的经济效益,不宜在该地区推广种植。

In order to choose the high quality of the development flue-cured tobacco varieties for Tianzhu, taking NC82, G28, Yun202 and 930032 as the tested varieties, and Yun85 and K326 for control, regional adaptability in the local ecological conditions and quality difference were tested. Test results showed that, the growth period of the tested varieties （strains） was 120-125 d, it was no obvious difference with Yun85 and K326; variety NC82 had the best dagronomic characters between the tested varieties （strains）, and balanced with K326, it showed poor of parietal lobe by G28, Yun202 and 930032; except that the natural disease resistance of NC82 performanced lower resistance to climate spot, the rest varieties （strains） were stronger; except that the economic characters of NC82 and K326 was balance, the rest varieties （strains） were lower economic benefit; it was the best inner quality by Yun202, it was the best sensory quality by 930032, the leaf quality were balance of the rest varieties （strains） by control. So, NC82 could moderate promotion in Tianzhu, but G28, Yun202, 930032 should not be cultivated because of lower economic benefit.
