摘要: 為篩選優(yōu)質(zhì),、適產(chǎn),、抗性好的白肋煙品種，對(duì)22 份白肋煙品種進(jìn)行了田間比較試驗(yàn),，主要研究形態(tài)特征,、農(nóng)藝性狀、原煙外觀品質(zhì),、田間病蟲害調(diào)查,，并對(duì)產(chǎn)量、產(chǎn)值,、上等煙率,、中等煙率4 個(gè)主要經(jīng)濟(jì)性狀進(jìn)行方差分析(ANOVA)。結(jié)果表明,，各品種在葉面性狀上存在差異,，在其他形態(tài)特征方面差異并不明顯；各品種農(nóng)藝性狀方面在株高,、莖葉角度、腳葉長(zhǎng),、腰葉長(zhǎng),、頂葉長(zhǎng)、主側(cè)脈夾角等性狀有較大差異,；經(jīng)濟(jì)性狀方面,，品種建雜80 號(hào)、日本白肋煙及Ky9 的產(chǎn)量,、產(chǎn)值相對(duì)較高,，品種Burley Skroniowski,、建雜80 號(hào)、日本白肋煙及Ky9 的上等煙率比較高,，中等煙率比較高的品種有Burley,、Burley Wloski、Ergo,、Ky34,、Ky56、S.K.,、Stamn D23-Nikotinarn,、White Burley 5、White Burley 2,、白肋煙-2 及選擇18 號(hào)多葉,；田間黑脛病自然發(fā)病情況顯示病情指數(shù)范圍為7.64～63.19，均值28.09,，極差55.55,，其中13 份抗病品種，3 份中抗品種,，5 份中感品種,，1 份感病品種。Abstract: 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 traits including yields, output value, rate 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 between stem and leaf, length of bottom leaves, length of waist leaves, length of upper leaves and angle of lateral to midrib of 22 varieties had significant difference. The varieties including Jianzha 80#, Japanese burley tobacco and Ky9 had higher yields, output value as well as rate of high-class leaf than others. The varieties including Burley, Burley Wloski, Ergo, Ky34, Ky56, Stam D23-Nikotinam, White Burley 5, White Burley 2, Burley-2 and select 18# with more leaves had higher rate of middle-class leaves. The index of black shank disease in tobacco field ranged 7.64-63.19, averaging 28.09, 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.
