以K 326为对照,对引自巴西、美国和津巴布韦等国家和河南、安徽等省的13个种质资源材料进行生育期、农艺性状、经济性状、外观质量、化学成分和抗病性等方面的比较和分析。结果表明,现蕾期有2个品种比对照K 326早7~8 d,有2个晚6~10 d;大田生育期有2个品种比K 326早11 d,2个晚7 d,其余各生育期接近K 326。13个品种中,分别有6个和5个抗和中抗TMV;分别有6个和4个抗和中抗黑胫病;分别有2个和7个抗和中抗南方根结线虫病。OX 414产量最高,产值第二;津引1号产量第二,产值、上等烟比例、均价、级指和产指均为第一;筑波1号产量第三;宣洞区、W 3-1-1、8022和小白筋产量和产值低于对照。OX 414、津引1号等品种生育期与对照接近,外观质量较好,化学成分协调,抗病性较强,经济性状优于对照。
Using K326 as a control, 13 germplasm resources from Brazil, the United States and Zimbabwe and other provinces in Henan, Anhui and other provinces were evaluated for their growth period, agronomic traits, economic traits, appearance quality, chemical composition and disease resistance Comparison and analysis. The results showed that in the budding stage, two cultivars were 7 to 8 days earlier than the control K 326, with 2 nights and 6 to 10 days. Two cultivars in the field had 11 days earlier than K 326 and 7 days later than K 326, and the rest There were 6 and 5 anti-TMV and 6 anti-TMV anti-TMV strains in each of the growing stages close to K 326.13, respectively, with 6 and 4 anti-and anti-shank pieces; 2 and 7 anti-and medium- Anti-Southern root knot nematode disease. OX 414 produced the highest output value of the second; Jin cited No. 1 output second, output value, superior smoke ratio, average price, level and index are the first; Tsukuba No. 1 production third; The yield and value of -1-1,8022 and the white bars were lower than the control. OX 414 and Jinyin 1 were close to the control, the appearance quality was better, the chemical composition was better, the disease resistance was stronger, and the economic traits were better than the control.
