烤烟新品种豫烟10号的选育及特征特性

Breeding of flue-cured tobacco variety Yuyan 10 and characters thereof

豫烟10号是以自选烤烟品系农大201为母本,云烟87为父本杂交,经系谱法定向选择培育而成。全国及河南省区域试验结果表明:该品种遗传性状稳定,田间生长整齐一致,田间长势强,耐肥性强,易烘烤;抗青枯病,中抗黑胫病和赤星病,中感根结线虫病、TMV、CMV和PVY;烤后原烟颜色均匀,结构疏松,油分较足,色泽均匀鲜亮,主要化学成分含量适宜,比例协调,烟叶感官质量较好。多年试验结果表明,该品种产量、产值、均价、上等烟比例等均高于对照NC89,是一个品质、抗性、产量、适应性等方面较能兼顾的优良新品种。

A new flue-cured tobacco variety Yuyan 10 was developed by hybridization method through pedigree selection with fluecured tobacco lines Nongda 201 as the female parent and widely cultivated variety Yunyan 87 as male parent. Results of regional fi eld trials in Henan province and national test showed that the new variety had stable genetic traits in the fi eld, high tolerance to high nitrogen fertilizer, resistance to bacterial wilt, medium resistance to black shank disease and tobacco brown spot disease and was easy to be fluecured and slightly susceptible to tobacco root knot nematode disease, TMV, CMV and PVY. Its cured leaf was rich in oil and had shining brightness and well-distributed orange color. The chemical composition was favorable and well proportioned to meet the requirements of manufacturing cigarettes with Chinese characteristics. The new variety had higher leaf yield, higher average price, higher ratio of high--rated leaf and higher production value than check variety NC89. In conclusion, Yuyan 10 was a new variety with good characters.
