摘要
为了选育优良的烟叶品种,对贵烟2号和2010A4两个品种(系)在天柱烟区进行了综合鉴定。结果表明:两个品种(系)株高、有效叶、腰叶长及宽均好于对照K326;大田生育期贵烟2号与K326接近,2010A4生育期较K326长;两品种(系)产值低于K326;根茎性病害贵烟2号抗性较差,低于K326,2010A4抗病性能与K326接近;两个参试品种(系)烟碱含量较为适中,钾、总糖及还原糖均较高,贵烟2号烟叶钾含量较为突出,氯含量偏低;中部烤烟叶的吸食品质前五项综合得分低于对照。综合来看,2010A4宜再次进行配套试验;贵烟2号不宜在天柱根茎性病害严重的烟区推广,但其钾含量高,有一定的优质烟叶特点,可选择区域示范种植。
In order to breed good tobacco varieties,taking Guiyan 2and 2010A4 as materials.Their traits were evaluated in Tianzhu tobacco growing areas.The results showed that plant height,effective leaves,length and width of waist leaf of two varieties(lines)were better than K326(CK);growing period in the field of Guiyan 2was close to that of K326,growth period of 2010A4 was longer than K326;output value of two varieties(lines)was less than K326;resistance for root disease of Guiyan 2was poor which was less than that of K326,2010A4 resistance was close to that of K326;nicotine content of two tested varieties(lines)was moderate,content of potassium,total sugar and reducing sugar of two tested varieties(lines)were higher,potassium content of Guiyan 2was more prominent,its chlorine content was low;the smoking quality comprehensive scores of flue-cured tobacco middle leaves of two tested varieties(lines)were lower than the control.Therefore,match test was better to conduct;Guiyan 2should not generalize in serious diseases areas of Tianzhu county,but the potassium content of Guiyan 2was high and it had the high quality tobacco characteristics,it could be planted in choosing regional demonstration.
