Effects of Different Reproduction Generation on Properties of Tobacco(Nicotiana tabacum) Varieties
摘要
Abstract
[Objective] The purpose was to study the effects of different years and different generations on properties of tobacco varieties. [Method] Field planting test of five flue-cured tobacco varieties'seeds, Jiyan No.7, Cuibi No. 1, K346, NC82 and V2, were carried out. [ Result] The results showed that the buding stage of NC82 was very early, while that of Jiyan No. 7 and Cuibi No. 1 were very late. For the same veriety, the buding stage of Jiyan No. 7, Cuibi No. 1, V2 were later along with the generation add, such as the buding stage of the seed collected at early year or in early generation was later 2 to 9 days than those of seeds collected at late year or in generation. The leaves of more varieties brought bigger (longer and wider) alang with the generation adding, and leaves increased or decreased. The yield of different varieties with different years had no marked difference, but the output value, rate of the first-class leaf and mean price had marked difference. The output value of Cuibi No. 1, NC82 and V2 descended along with the generation adding, and the mean price of the latest generation'seed was lower than those of the earliest generation'seed of all varieties. [Conclusion] The study provides a guidance for relatively researching on tobacco seeds reproduction generation.关键词
