-
摘要: 中煙103是從紅花大金元中獲得變異株，經(jīng)系統(tǒng)選育而成的,。該品種植株結(jié)構(gòu)合理,，遺傳性狀穩(wěn)定，田間長(zhǎng)勢(shì)強(qiáng),，易烘烤,；耐TMV,、CMV、PVY,，中抗黑脛病,，氣候斑點(diǎn)病輕，中感根結(jié)線蟲病,，感青枯病和赤星?。黄渲饕?jīng)濟(jì)性狀比對(duì)照品種NC89,、K326或紅花大金元有不同程度的提高,；烤后原煙橘黃色煙比例高，結(jié)構(gòu)疏松,，身份中等,，油分有-多，色度強(qiáng)-濃,，外觀品質(zhì)總體性狀優(yōu)于對(duì)照品種K326,；化學(xué)成分含量適宜，比例協(xié)調(diào),，與對(duì)照品種K326相比,，糖、鉀含量略高,，煙堿,、總氮含量略低。感官評(píng)吸與K326質(zhì)量檔次相當(dāng),。中煙103是一個(gè)質(zhì)量,、產(chǎn)量、抗病較能兼顧的具有紅花大金元香氣特征的烤煙新品種,，2007年通過(guò)全國(guó)煙草品種審定委員會(huì)審定,。Abstract: A new flue-cured variety zhongyan103 was developed by systematic selection from a mutant of honghua dajinyuan. The genetic traits of zhongyan103were stable and the plants grew uniformly and strongly in field. It was easier to cure than honghua dajinyuan. Zhongyan103 was resistant to TMV, CMV and PVY,moderately resistant to black shank, moderately susceptible to root knot nematode, susceptible to bacterial wilt and brown spot, yet less susceptible to tobacco weather fleck. Its main economic characters were better than the check(NC89, K326 or honghua dajinyuan). The cured leaves were mainly in orangecolor, oily to rich in gummy, with loose structure, medium body, strong to deep colour intensity. Zhongyan103 demonstrated better appearance quality thanK326, and favorable chemical components in harmonious proportion, with higher contents of reducing sugar and potassium, yet lower contents of nicotine andtotal nitrogen. With consistent sensory quality to K326, Zhongyan103 was good in quality, yield and disease resistance, and featured similar flavor notes tohonghua dajinyuan. It passed the Chinese tobacco variety evaluation in 2007.
