为筛选出适应安康烟区烟叶发育良好耐成熟的优质烤烟新品种(系),分别对‘云烟99’、‘云烟105’、‘6517’、‘PVH19’和‘K326’共5个品种(系)的生育期性状、植物学性状、农艺性状、抗病性、原烟外观和经济性状进行分析。结果表明,与对照‘K326’相比,‘云烟105’现蕾早,生育期长,留叶数较多,抗病性强,原烟外观质量较好,单位面积产量为2 134.5 kg/hm~2,单产值为39 274.8元/hm~2,上等烟率为39.07%,单叶重为8.4 g,在参试品种中表现好;‘云烟99’脚叶成熟较早,茎围最大,腰叶最大,抗病性强,原烟外观质量较好,单位面积产量为2 058 kg/hm~2,单产值为36 838.5元/hm~2,上等烟率为40.4%,在参试品种中表现好。建议‘云烟105’和‘云烟99’可作为搭配品种在安康主烟区适度种植。
In order to screen out new varieties (lines) of good quality flue-cured tobacco that are well-developed and well-tolerant to tobacco leaves in Ankang tobacco growing areas, five varieties (lines) of ’Yunyan 99’, ’Yunyan 105’, ’6517’, ’PVH19’ and ’K326’ ) Traits, plant characters, agronomic traits, disease resistance, the appearance of raw tobacco and economic traits were analyzed. The results showed that ’Yunyan 105’ had earlier buds, longer growth period, more leaves retained, stronger disease resistance and better quality of raw tobacco with a yield of 2 134.5 kg / hm ~ 2, the unit output value was 39 274.8 Yuan / hm ~ 2, the highest tobacco rate was 39.07% and the single leaf weight was 8.4 g, which showed good performance in the tested varieties. , The lumbar and leaf are the largest, the disease resistance is good, the quality of the raw tobacco is better, the yield per unit area is 2 058 kg / hm ~ 2, the output value is 36 838.5 yuan / hm ~ 2, the fine tobacco is 40.4% Good performance in the test varieties. Suggest that ’Yunyan 105’ and ’Yunyan 99’ can be used as matching varieties in the well-being of the main tobacco planting area.
