    白肋煙新品種YNBS1的選育及生產(chǎn)試驗(yàn)示范

    Breeding and Production Demonstration Trials of New Burley Tobacco Variety YNBS1

    • 摘要: YNBS1是用MSTN90與Ky907組配的雜交種,。經(jīng)過省區(qū),、國區(qū)品種比較、生產(chǎn)示范及內(nèi)外在質(zhì)量鑒定結(jié)果表明,，該品種長勢強(qiáng),，生長整齊，株型緊湊,，田間農(nóng)藝性狀一致性較好,。苗期50～55 d，大田生育期95～98 d，成熟集中,，易于砍收晾制,。耐肥，適應(yīng)性較強(qiáng),?？筎MV和黑脛病,中抗南方根結(jié)線蟲病，感赤星病,。生產(chǎn)示范平均產(chǎn)量比對照增加1.63%～8.63%,，產(chǎn)值增4.43%～12.54%，均價(jià)高0.23～0.27元/kg,，上等煙比例高2.70～3.70百分點(diǎn),。外觀品質(zhì)較好，化學(xué)成分指標(biāo)接近對照,，吸食品質(zhì)優(yōu)于對照,。具有良好的農(nóng)業(yè)經(jīng)濟(jì)效益和工業(yè)利用價(jià)值。

       

      Abstract: The new burley tobacco variety YNBS1 was developed by cross-breeding of MSTN90 and Ky907. Through provincial evaluation trials, national wide trials, production demonstration trials, and quality evaluation, the results showed that YBNS1 could grow vigorously and regularly with compact shape and uniform agronomic characters. It had 50-55 days of seedling stage and 95-98 days of field growth period. YNBS1 matured homogeneously, it could be cured easily, and had good tolerance to abundant fertilizers and wide adaptability. It showed resistance to TMV and black shank, moderate resistance to root knot and sensitive to brown spot. The yield, value, average price and the high grade cured leaf of YNBS1 in demonstration plots, compared to control plots, increased by 1.63%-8.63%, 4.43%-12.54%, 0.23-0.27yuan/kg, 2.70%-3.70%, respectively. With favorable appearance quality, chemical components and smoking quality, YNBS1, with regard to agricultural economic benefit and industry usability, is very promising.
