    烤烟新品种龙江925的选育及其特征特性

    Breeding of Flue-cured Tobacco Variety LJ925 and its Characteristics

    • 摘要: 龙江925是以高抗TMV的6603为母本、K326为父本杂交后经系谱法选育而成的常规纯系品种。该品种田间生长势强,较耐低温和干旱,高抗或免疫TMV,中感黑胫病、赤星病、黄瓜花叶病(CMV)、根结线虫和马铃薯Y病毒(PVY),感青枯病。较易烘烤,烤后烟叶柠檬黄到橘黄,9~13叶位还原糖含量21.00%,总糖24.74%,植物碱1.79%,总氮1.74%,K2O含量1.55%,Cl含量0.40%,淀粉含量5.51%,内在化学成分在适宜范围内。主要经济指标、外观质量和感官质量优于对照NC89。该品种抗逆性较强,烤后烟叶质量较好,适合北方干旱地区或重茬地块种植,注意适时早栽烟,预防马铃薯Y病毒病。

       

      Abstract: LJ925 was developed by crossing 6603 as female parent with high resistant to tobacco mosaic virus and K326 as male parent through hybridization and pedigree selection. LJ925 grew strongly in fields, was high resistant to tobacco mosaic virus, moderately susceptible to blank shank, brown spots, mosaic virus and root-knot nematode, susceptible to granville wilt. LJ925 was easy to cure, and the colors of cured leaves were lemon to orange. Leaf chemical composition of 9-13 positions was acceptable, with reductive sugar 21.00%, total sugar 24.74%, alkaloid 1.79%, total nitrogen 1.74%, K2O 1.55%, chlorine 0.40%, starch 5.51%. Comparing with NC89, LJ925 had better economic value, better appearance quality and smoking quality. LJ925 had wide adaptability and good quality, and it can be grown in drought areas or continuous cropping fields, and should be transplanted earlier, and with caution of potato virus Y.
