    煙草與曼陀羅屬間雜交育種研究

    Research on distant hybridization between tobacco and stramonium

    • 摘要: 利用煙屬的普通煙草品種龍煙2號與曼陀羅屬的曼陀羅進行屬間遠緣雜交育種,培育含阿托品及莨菪烷生物堿的新型煙草,,滿足患哮喘,、咳嗽等病癥,,但又難以戒煙的消費者的需要。采取無性與有性雜交相結(jié)合的方法克服雜交不孕,。經(jīng)酶譜及RAPD分子檢測,,穩(wěn)定的雜種后代含有雙親的遺傳物質(zhì);醫(yī)藥成分與單料煙煙氣檢測結(jié)果表明,,穩(wěn)定的雜種后代,,都含阿托品、東莨菪堿,;鏡檢結(jié)果表明,,F1-F18代細胞染色體呈雜合狀態(tài);卷煙工業(yè)驗證其具有較高的利用價值,。

       

      Abstract: By means of distant hybridization between Longyan II ?穴 a variety of Nicotiana tabacum?雪 and stramonium?熏 new-type tobacco which contained atropine and scopolamine was expected to be incubated to meet the needs of consumers who were suffering asthma and cough but couldn’t stop smoking. The hybridization method of asexuality combined with sexuality was used to overcome the infertility after hybridization. The isoenzyme identification and RAPD analysis showed that the filial generation contained genetic materials from both parents. The detection of medical ingredients and smoke of mono-tobacco cigarette indicated that the filial generation contained atropine and scopolamine. The result of the microscope detection showed that F1-F18 cell chromosome were heterozygosis. It was proved by the cigarette factory after many experiments that the new-type tobacco had comparably high utility value.
