摘要: 豫煙6號是以MSK326為母本,，自選烤煙品系農(nóng)大202為父本雜交育成的雜交種。該品種農(nóng)藝性狀穩(wěn)定,，田間生長整齊一致,，抗旱性強，抗黑脛病,，中抗青枯病,，煙葉鉀含量較高，烤后原煙多橘黃,，油分多,，色度強，化學成分含量適宜,，比例協(xié)調(diào),，煙葉質(zhì)量符合中式卷煙需要；與對照品種NC89比較,，煙葉產(chǎn)量提高19.03%,，產(chǎn)值提高44.86%，均價提高10.70%,上等煙比例增加20.42%,；是一個品質(zhì),、抗性、產(chǎn)量,、適應(yīng)性等方面較能兼顧的優(yōu)良新品種,，特別適宜在雨養(yǎng)煙區(qū)種植。Abstract: Yuyan6 was developed by crossing MSK326 with ND202. Yuyan6 has stable agronomic traits and can grow rather uniformly in field. Yuyan6 has higher drought tolerance, resistance to black shank disease, medium resistance to bacterial wilt, and high potassium content. Its cured leaves are rich in oil, and have shining bright and well distributed orange color. The chemical composition of leaves is favorable and well proportioned, and can meet the requirement of tobacco industry. Compared with the check variety NC89, the leaf yields, yield value, average price and ratio of high class leaf of Yuyan6 can increase by 19.03%, 44.86%, 10.70 % and 20.42%, respectively. With high quality, yields and wide adaptability, Yuyan6 is suitable for China’s north tobacco growing areas, especially with drought conditions.
