【摘要】 为研究烤烟新品种在湖南省郴州烟区的适应性和抗逆性,2018年以K326和云烟87为对照,对SY15230、H4、09-18-3、CZ-59、HKND-2和20132这6个品种(系)进行区域筛选试验,调查了参试新品种的植物学性状、农艺性状、经济性状、抗逆性,综合评价了烟叶外观质量等。结果表明:6个品种(系)在植物学性状、农艺性状方面存在一定的差异,但都能适应湖南郴州烟区生态环境要求;在经济性状方面,09-18-3产量和产值最高,其次为SY15230和CZ-59;CZ-59上等烟比例最高;09-18-3烟叶成熟落黄好,结构合理,抗病性强;SY15230农艺性状较好,植株较高,有效叶多,叶面积适中,成熟时分层落黄好;CZ-59田间生长势强,叶面积大,上等烟率较高;20132易感黑胫病和野火病,产量低;HKND-2和云烟87易感野火病;SY15230、09-18-3和CZ-59原烟外观质量综合评价较好。综上所述,烤烟新品种(系)SY15230、CZ-59和09-18-3适宜在湖南郴州烟区种植。更多还原

【Abstract】 In order to study the adaptability and stress resistance of new flue-cured tobacco varieties in Chenzhou tobacco area,Hunan Province,in 2018,with K326 and Yunyan 87 as the control,the six varieties (lines) SY15230,H4,09-18-3,CZ-59,HKND-2 and 20132 were selected for regional screening test.The botanical traits,agronomic traits,economic traits and stress resistance of the new varieties were investigated,and the appearance quality of tobacco was comprehensively evaluated.The results showed that the six varieties (lines) had some differences in botanical traits and agronomic traits,but could meet the requirements of the ecological environment of Chenzhou tobacco area;in terms of economic traits,09-18-3 had the highest yield and output value,followed by SY15230 and CZ-59,and CZ-59 had the highest proportion of high class tobacco;09-18-3 tobacco leaves had good mature yellowing,reasonable structure and strong disease resistance;SY15230 had good agronomic characters,high plants,many effective leaves,moderate leaf area and good layered yellowing at maturity;CZ-59 had strong growth potential in the field,large leaf area and high rate of high class tobacco;20132 was susceptible to black shank and wildfire disease,with low yield;HKND-2 and Yunyan 87 were susceptible to wildfire disease;the appearance quality of SY15230,09-18-3 and CZ-59 crude tobacco was evaluated well.In conclusion,SY15230,CZ-59 and 09-18-3 are suitable for planting in Chenzhou tobacco area.更多还原
