烤烟新品种许金101的选育及特征特性

为了选育抗根部病害的烤烟新品种，以南江3号为母本、双抗70为父本，得到纯系品种许金101。多年试验结果表明，该品种遗传性状稳定，主要经济性状优于对照NC89和中烟100。抗镰刀菌根腐病，中抗黑胫病和根结线虫病，中感青枯病、CMV和PVY，综合抗病能力与NC89相当；烘烤特性好，烤后原烟外观质量较好，化学成分较协调，能够满足工业企业的需要。该品种根部病害抗性较好，特别是对镰刀菌根腐病的抗性提高，适宜在我国黄淮烟区特别是平原区种植。

Breeding and Characterization of a New Flue-cured Tobacco Variety Xujin 101

In order to obtain new flue-cured tobacco varieties with improved resistance to root diseases, Xujin 101 was bred from Nanjiang No.3 as the female parent and Shuangkang 70 as the male parent. The results of many years' tests showed that the genetic traits of this variety are stable, and the main economic characters are better than that of NC89 and Zhongyan 100. Xujin 101 is resistant to Fusarium mycorrhizal rot, middle resistant to black shank and root knot nematode, middle sensitive to bacterial wilt, CMV and PVY, and its comprehensive resistance to disease is comparable to that of NC89. The variety has good baking characteristics, and good appearance quality of roasted tobacco leaves. The chemical composition is more coordination, and integrated performance can meet the needs of industrial enterprises. The resistance of this variety to root diseases was better, especially to Fusarium mycorrhizal rot. It is suitable for planting in Huanghuai tobacco areas, especially in the plain area, and the potential for popularization and application is great.
