摘要: 烤煙新品種豫煙四號( 6614) 是以許金一號為母本, Coker176 為父本, 用系譜法選育而成,。2006 年3 月通過全國煙草品種審定委員會審定。經(jīng)過多年多點試驗, 其主要農(nóng)藝性狀穩(wěn)定, 田間生長整齊一致, 田間自然株高135.6 cm, 打頂株高90.78 cm, 有效葉20- 22 片, 腰葉長58- 65 cm,腰葉寬30- 35 cm, 葉形寬橢圓, 葉面較平, 葉片厚薄適中, 著生均勻,?；ㄐ蚓o湊, 花色淡紅色。田間生長勢強, 大田生育期110- 113 d, 抗黑脛病,、中抗根結線蟲病,、黃瓜花葉病, 感赤星病。耐旱,、耐瘠薄,田間葉片分層落黃, 易烤,。烤后原煙顏色橘黃, 油分較多, 色度較強, 結構疏松, 葉片厚度適中,?？偺呛?3.72%, 還原糖19.37%, 煙堿2.82%, 總氮1.8%, 蛋白質8.19%, 鉀含量1.23%, 主要成分含量適宜, 內(nèi)在化學成分協(xié)調(diào)。平均產(chǎn)量2273.83 kg / hm2 左右, 均價7.01 元/ kg, 上等煙比例21.86%,。產(chǎn)值15909.22 元/ hm2,。綜合性狀優(yōu)于對照NC89。Abstract: A new flue- cured tobacco variety Yuyan 4 was developed from Xujin 1(female parent) and coker176 (male parent) with a genealogy method and passed the national tobacco evaluation in March 2006.The results of multi- location trials for several years showed that with stable agronomic characteristics, Yuyan 4 grew uniformly and vigorously in field and had a growing period of 113- 110 days. It was resistant to black shank, moderately resistant to root- knot nematode and CMV. Its leaves matured well layer by layer and easy to be cured. The cured leaves were in orange color, loosely structured, oily with strong aroma and average body. The content and ratio of the major chemical components were suitable. Its average yield, price, first grade leaf proportion, output value were 2273 kg / hm2,7.01yuan / kg,21.86% and 15909.22 yuan / hm2, respectively. Yuyan 4 is superior in terms of general characteristics compared with the control variety NC89.
