延边7 份新编目烤烟种质资源特征特性分析

Characteristics of Seven New Strain Resources of Flue-cured Tobacco

摘要: 研究了参加编目的7 份烤烟新品系资源的生育期、形态特征、主要农艺性状、田间主要病害的自然发病情况等，分析了各品系的主要农艺性状、经济性状、原烟外观质量及田间主要发病情况的差异性。结果表明，参试品系的主要农艺性状和田间主要发病情况均没有显著差异，但JZ7-02、JZ7-04、JZ7-07 三个品系比对照品种节距长，腰叶宽，经济性状表现较好。各参试品系的全生育天数为174~186 d，原烟外观质量为光泽中～强，油分中～有，颜色较深且均匀，叶片结构疏松，叶片厚度适中。

Abstract: Seven new flue-cured tobacco resources were studied for their growth period, morphological characteristics, agronomic traits, and natural diseases, etc. The results showed that between these strains, agronomic traits and natural disease had no significant difference. The pitchs and leaf widths of JZ7-02, JZ7-04 and JZ7-07 were larger than the control variety. Growth period for all of these strains were between 174 and 186 days. Luster was from moderate to strong. Oil was from middle to existence. Color was uniform and frame was loose and thickness was moderate.
