    • 摘要: 烤煙新品種吉煙九號是根據性狀互補原理，用抗病性好、抗逆性強、易烤、豐產性品系9501為母本，引進加拿大的優(yōu)質品種溫德爾為父本進行雜交，經系普法選擇，于2000年育成。2006年1月通過省級評審，2007年10月通過全國煙草品種審定委員會審定。吉煙九號原煙顏色多金黃—正黃，油分多—有，結構疏松，身份適中；總糖26.59%，煙堿1.78%，糖堿比13.09，主要化學成分適宜，比例協(xié)調；卷煙評吸香氣質好，香氣量足，具中偏清香型風格。其綜合性狀巧妙地集兩親本優(yōu)點于一體。據品系比較試驗、省區(qū)試、全國區(qū)試、省和國家生產試驗結果，吉煙九號平均產量2 599.01 kg / hm2，較對照NC89增產20.47%，平均產值19 221.69元/ hm2，較對照增收41.2%，增產（增收）顯著。吉煙九號對TMV免疫，中抗PVY和根結線蟲病，感黑脛病，其它病害抗性與NC89相當。吉煙九號具有抗旱、抗?jié)场⒖购⒖乖缁ā⒛头省⒛涂竞鸵卓镜葍?yōu)點。
