| 摘 要： | 为筛选出适宜云南文山烟区种植的津巴布韦烤烟品种,选择该国培育并引入我国的KRK26,KRK22,KRK23和T29,以当地主栽品种K326和云烟87为对照进行同田对比试验.结果表明：1）津巴布韦品种总体表现为植株较高、节距较稀、叶片较宽、叶色浅绿、现蕾较晚、大田生育期较长、抗倒伏和抗黑胫病的能力较弱、原烟叶片偏薄等特点.2）KRK26的产量为3 187.5 kg/hm^2,产值为50 426元/hm^2,均价为15.82元/kg,级指为74.62,产指为2 378.6,上等烟比例61.51%,极显著高于K326,与云烟87相当;而其余3个津巴布韦品种的经济性状,与K326相当,但极显著低于云烟87.3）KRK26烟叶的氧化钾含量（质量分数）2.58%最高,两糖差5.08最小,总糖、烟碱及其比值均在适宜范围内,且其余3个津巴布韦品种也表现出糖含量较低,钾含量较高等特点.

| Abstract: | In order to select the ideal flue-cured tobacco varieties introduced from Zimbabwe for planting in Yunnan Wenshan.Four Zimbabwe varieties of KRK26,KRK22,KRK23 and T29 and the two checks of K326,and Yunyan 87 were chosen to carry out variety comparison test.The results showed that：1）The tobacco varieties of Zimbabwe had higher plant-height,longer pitch,wider and light-green leaf,later budding,longer growth and developing period,relatively weaker abilities of anti-lodging and resistant to black shank,and thinner cured leaves.2）The comprehensive economic characters of KRK26 were the best,which had better yield,output value,average price,harvest index and the higher proportions of high grade leaves.And the rest three varieties of Zimbabwe had the similar economic characters to K326,but significantly below Yunyan 87.3）The leaves of KRK26 had the highest content of potassium oxide,the minimum sugars difference between total sugar and reducing sugar,ideal content of total sugar and nicotine,and suitable the ratio of the total sugar to nicotine in all tested varieties.The rest three varieties of Zimbabwe showed lower content of sugars and higher K2O. |
