延邊7 份新編目烤煙種質(zhì)資源特征特性分析

Characteristics of Seven New Strain Resources of Flue-cured Tobacco

摘要: 研究了參加編目的7 份烤煙新品系資源的生育期、形態(tài)特征,、主要農(nóng)藝性狀,、田間主要病害的自然發(fā)病情況等，分析了各品系的主要農(nóng)藝性狀,、經(jīng)濟(jì)性狀,、原煙外觀質(zhì)量及田間主要發(fā)病情況的差異性。結(jié)果表明,，參試品系的主要農(nóng)藝性狀和田間主要發(fā)病情況均沒(méi)有顯著差異,，但JZ7-02、JZ7-04,、JZ7-07 三個(gè)品系比對(duì)照品種節(jié)距長(zhǎng)，腰葉寬,，經(jīng)濟(jì)性狀表現(xiàn)較好,。各參試品系的全生育天數(shù)為174~186 d，原煙外觀質(zhì)量為光澤中～強(qiáng),，油分中～有,，顏色較深且均勻,，葉片結(jié)構(gòu)疏松，葉片厚度適中,。

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.
