摘要
烤烟新品种‘云烟121’田间长势强、较易烘烤,产量产值和品质较能兼顾。为评价‘云烟121’成为曲靖烟区后备品种的潜力,2018—2020年在曲靖9个县(区)进行新品种筛选试验。‘云烟121’和主栽对照品种进行邻田种植,种植面积0.66~1.0 hm^(2)。曲靖市烤烟生长季2018年呈现前期高温、后期干旱的情况;2019年5月和6月上旬干旱,8月降雨偏少;2020年5—7月遭遇严重干旱。3年多点试验结果表明,在‘云烟97’种植区,‘云烟121’株高比对照‘云烟97’高2 cm,可采叶数比对照‘云烟97’多1~2片,‘云烟121’的产值与‘云烟97’相当。在‘云烟87’种植区,‘云烟121’株高比对照‘云烟87’高4 cm,‘云烟121’的产值比对照‘云烟87’高4%。上部叶和中部叶的糖碱比同一地点品种间差异较小,不同地点间差异明显大于品种间差异,‘云烟97’种植区地点间差异大于‘云烟87’种植区。中部叶原烟样品由4~5家中烟工业公司按照感官质量从高至低排序,‘云烟121’的综合排名介于‘云烟87’和‘云烟97’之间。2021—2023年曲靖‘云烟121’累计推广42733 hm^(2),‘云烟121’在PVY危害较重或‘云烟87’和‘云烟97’长势弱的区域具有良好的推广价值。
The new flue-cured tobacco variety‘Yunyan 121’has strong growth vigor in the field and is easy to cure,and the yield and leaf quality can be balanced.In order to evaluate the potential of‘Yunyan 121’as a reserve variety in Qujing tobacco area,new varieties screening tests were carried out in 9 counties in Qujing from 2018 to 2020.The method was to plant 0.66-1.0 hm^(2) of‘Yunyan 121’while the main control variety was planted in adjacent field.In Qujing,the tobacco growing season experienced high temperatures in early stage of 2018 and drought later;in 2019,there was drought in May and the first ten days of June,with less rainfall in August;in 2020,severe drought occurred from May to July.The results of 3-year multi-point test showed that in the planting area of‘Yunyan 97’,the plant height of‘Yunyan 121’was 2 cm higher than that of the control‘Yunyan 97’,the number of available leaves was 1-2 more than that of the control‘Yunyan 97’,and the output value of‘Yunyan 121’was equivalent to that of‘Yunyan 97’.In the‘Yunyan 87’area,‘Yunyan 121’was 4 cm higher in plant height,4%higher in yield than the control‘Yunyan 87’.The differences of sugar-nicotine ratios of the upper and middle leaves among varieties were smaller in the same place,and the differences between locations were significantly greater than those between varieties.The differences between locations in‘Yunyan 97’planting area were greater than those in‘Yunyan 87’planting area.Middle leaf raw tobacco samples were ranked by 4-5 Chinese tobacco industrial companies according to their sensory quality,and the overall ranking of‘Yunyan 121’was between‘Yunyan 87’and‘Yunyan 97’.From 2021 to 2023,‘Yunyan 121’had a cumulative promotion of 42733 hm^(2) in Qujing.‘Yunyan 121’had good promotion value in areas with heavy PVY damage or weak growth of‘Yunyan 87’and‘Yunyan 97’.
