[目的] 研究烤烟雄性不育杂种一代"9803"的选育及鉴定.[方法] 以高代稳定不育系MSG80为母本,以引进的抗病性强且品质优的NC55做父本,通过杂交育种,获得F_1代杂交种"9803",通过多年品种试验,对该品系的主要植物学性状和农艺性状进行评价.[结果] 多年试验结果表明,"9803"适应性强,抗逆性强,主要经济性状(产量、均价、产值、上等烟和中上等烟比例)、感官质量(香气量、浓度、余味)和抗病性(PVY、赤星病、根结线虫病、青枯病)参数明显优于对照NC89,但其他外观质量(叶片结构、色泽、身份)、化学成分(烟碱、总氮、还原糖、总糖、钾、氯、淀粉)、香气质及抗TMV、CMV、黑胫病参数则与对照NC89相当.[结论] " 9803"是一个品质、抗病性、抗旱性、产值等综合性状兼顾的优良新品系.

[Objective] The aim was to research the breeding and evaluation of flue-cured tobacco male sterile F_1 hybrid 9803.[Method] Taking the advanced stable sterile line MSG80 and the introduced NC55 with strong disease resistance and excellent quality as the female parent and the male parent resp.the F_1 hybrid 9803 was obtained through cross breeding.The main botany and agronomy character of the line were evaluated through the variety test for several years.[Result] Several years tests showed that 9803 was strong in adaptability and stress resistance, whose parameters of the main economic features including yield, mean price, value of output, high class leaf, high middle class leaf, the sensory quality including aroma amount, concn., aftertaste and disease resistances on PVY, brown spot, root knot nematode and bacterial wilt were better than that of CK NC89 obviously.But the other parameters of appearance quality including leaf structure, color, identity, chemical composition including nicotine, total nitrogen, reducing sugar, total sugar, K, Cl, starch, aroma quality, and resistances on TMV, CMV, black shank were equal to that of CK NC89.[Conclusion] 9803 was a new excellent line with good comprehensive characters in quality, disease resistances, drought resistance and production value etc.
