-
摘要: 閩煙7號(hào)（K07）是以云煙85為母本與抗青枯病的美國(guó)優(yōu)質(zhì)品種Coker347為父本,，經(jīng)常規(guī)雜交、系譜法定向選擇而成,。試驗(yàn)結(jié)果表明,，該品種適應(yīng)性較強(qiáng)，耐肥水,，易烘烤,；抗黑脛病，中抗青枯??；烤后原煙呈桔黃色，油分足,，色澤均勻鮮亮,，主要化學(xué)成分含量適宜，比例協(xié)調(diào),，煙葉評(píng)吸質(zhì)量好,。福建省區(qū)試和全國(guó)區(qū)試多年結(jié)果表明，閩煙7號(hào)的煙葉產(chǎn)量,、均價(jià)、上等煙比例,、產(chǎn)值等均高于對(duì)照K326,，是一個(gè)品質(zhì)、抗性,、產(chǎn)量等綜合性狀較能兼顧的優(yōu)良烤煙新品種,。Abstract: Through hybridization and pedigree selection, a new flue-cured tobacco variety Minyan 7 was developed by crossing the female parent tobacco variety Yunyan 85 and the male parent variety Coker 347 which is resistant to tobacco bacterial wilt (Ralstonia solanacearum). Results showed that the new variety Minyan 7 had good adaptability, favored fertile soil, and was easy to cure. It was resistant to tobacco black shank and medium resistant to tobacco bacterial wilt. The cured leaf was rich in oil and had shining bright and well-distributed orange color. It has the favorable and well-proportioned chemical composition and good smoking-quality to meet the requirements of manufacturing cigarettes with Chinese characteristics. According to the results of tobacco varieties regional test in fujian province and Chinese southern area, the new variety Minyan 7 had higher leaf yield, higher average price, higher ratio of the high and middle class leaf and higher production value than the check variety K326. In conclusion, Minyan7 was a new variety with good comprehensive characters.
