美引烤烟品种在黑龙江烟区的生态适应性研究

为探究几个美引烤烟品种在黑龙江烟区的生态适应性，筛选适宜在黑龙江种植的烤烟新品种，以‘NC89’为对照，对‘Yatas13’、‘Yatas14’、‘Yatas15’、‘Yatas16’、‘Yatas17’、‘Yatas18’等6 个美引烤烟新品种进行生态适应性种植试验。‘Yatas14’大田生长势强，经济效益最佳，抗病性好；‘Yatas13’、‘Yatas15’和‘Yatas17’在产量和产值方面优于对照，但PVY 和TMV的田间自然发病情况比对照‘NC89’严重；‘Yatas16’和‘Yatas18’在抗病性、经济性状等方面表现不良。‘Yatas14’的综合性状最好，对黑龙江烟区的生态适应性较强，建议今后扩大种植面积示范种植； ‘Yatas13’、‘Yatas15’和‘Yatas17’建议第2 年继续种植验证；淘汰‘Yatas16’和‘Yatas18’。

Adaptability of America Introduced New Flue-cured Tobacco Varieties in Heilongjiang Tobacco-growing Area

The aim is to explore the ecological adaptability of several varieties of flue-cured tobacco in Heilongjiang and to select new flue-cured tobacco varieties suitable for Heilongjiang flue-cured tobacco growing areas.A variety comparison experiment was conducted on'Yatas13','Yatas14','Yatas15','Yatas16','Yatas17'and'Yatas18',which were introduced from America,using'NC89'as the control.The results showed that'Yatas14'exhibited strong growth,the highest economic benefit,and high disease resistance.The yield and production value of'Yatas13','Yatas15'and'Yatas17'were better than that of the control,but the field disease occurrence of PVY and TMV was more serious than that of the control'NC89'.'Yatas16'and'Yatas18'had worse yield and output value in comparing with the control.'Yatas14'showed better comprehensive characters,and adapted to the ecological conditions of Heilongjiang,the variety should be further demonstrated in Heilongjiang flue-cured tobacco growing areas.'Yatas16'and'Yatas18'were suggested to be eliminated.
