摘要
为在铜仁地区筛选出适宜的烤烟品种,对10个不同基因型烤烟品种的农艺性状、抗病性和经济性状进行了比较分析。结果表明:从农艺性状来看,PB4在株高、自然叶片数、可采叶片数、腰叶长均优于其他品种;从抗病性来看,只有PB4未感染根茎性病害,综合抗病性较好;从经济性状来看,PB6、PB4的产值、均价和中上等烟比例较高。因此,试验确定PB6和PB4两个烤烟品种适合在铜仁地区推广种植。
This experiment was conducted to identify and select some suitable tobacco varieties with different genotypes on agronomiccharacters,disease resistance and economic characters in and for Tongren.The results showed that the plant height,number of naturalleaves,number of available leaves,and blade length of tobacco variety PB4were greater than those of the other varieties;the red spotdisease rate of PB2was higher,the incidence of climate spot of PB4was higher,the mosaic disease and root-stem disease rates of PB1were higher,and comprehensively PB4was of low disease incidence;and the different genotypes varied in the tobacco yield,output value,high-quality ratio and average price.The tobacco output value,high-quality ratio and average price were the highest in PB6and PB4.Insummary,PB6and PB4were suitable for introduction and cultivation in Tongren tobacco areas.
