烤烟新品种龙烟101的选育及特征特性

龙烟101是以优质、抗烟草普通花叶病毒病（tobaccomosaicvirus，TMV）、适应性强为育种目标，采用烤烟品种龙江925为母本，抗TMV品种CV91为父本，杂交后经系谱法选育而成的免疫TMV烤烟新品种。多年试验结果表明，龙烟101遗传性状稳定，植株结构及田间群体结构合理，田间生长势强、耐连作；免疫TMV，中抗黑胫病，靶斑病较轻，感青枯病、CMV和PVY，综合抗性与对照NC89相当；主要经济性状和原烟外观质量优于对照NC89，化学成分较适宜，感官质量与对照NC89相当。综合评价，龙烟101在品质、产量和抗病、抗逆性等方面均较好，适宜东北烟区和黄淮部分烟区种植。

Breeding and Characterization of a New Tobacco Variety Longjiang101

In order to obtain new flue-cured tobacco varieties with high quality, suitable yield and tobacco mosaic virus (TMV) resistance, Longyan101 was bred with Longjiang925 as the female parent and CV91 as the male parent using classical breeding selection methods. The new variety was certified by the National Tobacco Variety Examination and Approval Committee in September, 2020. The results of variety tests showed that the genetic characters of Longyan 101 were stable and the continuous cropping plants grew strongly with reasonable plant structure and population structure in the field. Longyan101 showed equal disease resistance to NC89, being immunized with TMV, moderately resistant to black shank and certain resistant to target spot disease, sensitive to bacterial wilt, CMV and PVY. The main economic characters and appearance of Longyan101 were better than NC89, chemical composition and sensory quality evaluation were equal to NC89. In summary, Longyan101 could be widely planted in the northeast tobacco-growing area with better resistance to TMV, better quality and better economic benefits.
