部分白肋烟品种资源鉴定与评价

为筛选优质、适产、抗性好的白肋烟品种,对22份白肋烟品种进行了田闻比较试验,主要研究形态特征、农艺性状、原烟外观品质、田间病虫害调查,并对产量、产值、上等烟率、中等烟率4个主要经济性状进行方差分析(ANOVA).结果表明,各品种在叶面性状上存在差异,在其他形态特征方面差异并不明显;各品种农艺性状方面在株高、茎叶角度、脚叶长、腰叶长、顶叶长、主侧脉夹角等性状有较大差异;经济性状方面,品种建杂80号、日本白肋烟及Ky9的产量、产值相对较高,品种Burley Skroniowski、建杂80号,日本白肋烟及Ky9的上等烟率比较高,中等烟率比较高的品种有Burley、Burley Wloski、Ergo、Ky34、Ky56、S.K.、 Stamn D23-Nikotinam,White Burley 5,White Burley 2、白肋烟-2及选择18号多叶;田间黑胫病自然发病情况显示病情指数范围为7.64～63.19,均值28.09,极差55.55,其中13份抗病品种,3份中抗品种,5份中感品种,1份感病品种.

Identification and Evaluation of Burley Tobacco Germplasm

In order to select high quality burley tobacco varieties, field comparison test of 22 burley tobacco varieties was conducted with comparison analysis on morphologic character, agronomic character, appearance quality, variance analysis on main economical of high-class leaves and rate of middle-class leaves. The results showed that morphologic characters of 22 varieties had no significant difference except for leaf surface. Agronomic characters including plant height, angle er leaves and angle of lateral to midrib of 22 varieties had significant difference. The varieties including Jianza 80~#, Japanese burley tobacco and Ky9 had higher yields, output an others. The varieties including Burley, Burley Wloski, Ergo, Ky34, Ky56, Stam D23-Nikotinam, White Burley 5, White Burley 2, Bttrley-2 and select 18~# with more leaves had higher rate of middle-class leaves.9, and with distance of 55.55. The 22 tested varieties included 13 resistance varieties, 3 moderate resistance varieties, 5 moderate susceptive varieties and 1 susceptive variety.
