摘要
[Objective] The aim was to select the new flue-cured tobacco varieties suitable for Heilongjiang flue-cured tobacco areas. [Method] A comparative trail of six new flue-cured tobacco varieties, which were introduced from America and Brazil, including PVH2248, PVH2291, PVH2310, PVH2269, NC196, and PVH2254, were identified, using NC89 as control. [Result] PVH2310 had good botanical char- acters and agronomic traits; the time from transplanting to budding was 56.00 d, and from budding to center flower blooming was 64.33 d, and the growth period in field is 119.00 d; TMV and PVY did not occur in the year of these two diseases occurring widely; its yield was 3 536.55 kg/hm2; its output value was 44 792.25 CNY/hm2; its average price was 12.68 CNY/kg; its proportion of the superior tobac- co was 19.61%; its appearance quality of raw tobacco was good and equal to NC89 in control group; its tobacco leaf＇s main chemical components content was suitable and internal chemical components were coordinated. [Conclusion] PVH2310 and PVH2269 both performed excellently in terms of comprehensive characteristics, which should be further demonstrated in Heilongjiang flue-cured tobacco areas.
[目的]为筛选适合黑龙江烟区的烤烟新品种。[方法]以NC89为对照,对新引进的PVH2248、PVH2291、PVH2310、PVH2269、NC196、PVH2254等6个美国和巴西烤烟新品种进行比较鉴定。[结果]PVH2310植物学性状和农艺性状优良;移栽至现蕾56.00 d,移栽至中心花开64.33 d,大田生育期119.00 d;在烟草普通花叶病毒(TMV)和马铃薯Y病毒(PVY)普遍发生年份未发生以上病害;产量3 536.55kg/hm2,产值44 792.25元/hm2,均价12.68元/kg,上等烟比例19.61%;原烟外观质量较好,与对照品种NC89相当;烟叶主要化学成分含量适宜,内在化学成分协调。PVH2269植物学性状和农艺性状也较优良;移栽至现蕾56.67 d,移栽至中心花开65.67 d,大田生育期较长,126.00 d;TMV轻微发生,病指0.25,PVY病指2.21;产量3 384.30 kg/hm2,产值38 398.95元/hm2,均价11.35元/kg,上等烟比例22.82%;原烟外观质量较好,与对照品种NC89相当;烟叶主要化学成分含量适宜,内在化学成分协调。[结论]PVH2310和PVH2269综合性状表现较好,可以在黑龙江烟区进一步示范验证。
