八个外引烤烟品种在韶关生态烟区筛选及适宜性评价

为了筛选出适宜韶关生态烟区的烤烟品种,采用大田比较试验,研究了8个外引烤烟品种在农艺性状、病害发生、经济性状、外观质量、感官质量以及化学成分等方面的差异,结果表明：与对照‘K326’相比,‘FJ312’、‘闽烟7号’和‘云烟87’综合表现突出,其株高在78.0~108.5 cm间,最大叶面积在1167.41~1454.26 cm²;产量在1727.05~2178.67 kg/hm²间,较对照‘K326’显著提高20.83%~52.43%,产值在43368.90~58946.13元/hm²间,较对照‘K326’显著提高29.68%~76.26%;三者的抗病性、外观质量和感官质量均优于对照‘K326’,其中‘FJ312’和‘闽烟7号’的抗病性最强,其烟草花叶病、烟草青枯病、烟草赤星病发生率为0。总的来说,‘FJ312’、‘闽烟7号’和‘云烟87’在韶关烟区适应性较好,可作为当地的后备烤烟品种,具有一定的推广应用前景。

Selection and Suitability Evaluation of Eight Introduced Flue-cured Tobacco Varieties in Shaoguan Ecological Tobacco Areas

To screen out suitable flue-cured tobacco varieties in Shaoguan ecological tobacco areas, a field comparative experiment was conducted to study the differences of eight introduced flue-cured tobacco varieties on agronomic traits, disease occurrence, economic traits, appearance quality, sensory quality and chemical composition. The results showed that the field comprehensive performance of ‘FJ312’, ‘Minyan 7’and‘Yunyan 87’ were better than that of the control ‘K326’, the three varieties’ plant height was 78.0 to 108.5 cm, and the maximum leaf area was 1167.41 to 1454.26 cm²; the yield was 1727.05 to 2178.67 kg/hm², which was 20.83%-52.43% higher than that of ‘K326’; the output value was 43368.90 to 58946.13 yuan/hm², which was 29.68%-76.26% higher than that of ‘K326’. The disease resistance, appearance quality and sensory quality of the three varieties were better than those of ‘K326’, and ‘FJ312’ and ‘Minyan 7’ had the strongest disease resistance, whose incidence rate of the tobacco mosaic virus, tobacco bacterial wilt and tobacco brown spot were zero. In a word, ‘FJ312’, ‘Minyan 7’ and ‘Yunyan 87’, which are adaptable in Shaoguan ecological tobacco areas, can be used as local backup flue-cured tobacco varieties and have certain application prospects.
