Cultivation of Lilium pumilum DC.new variety'Yandan No.1'
New varieties of Lilium pumilum DC.were cultivated with Lilium pumilum DC.and Lilium davidii var as parents.Callus was induced by establishing clones of Lilium pumilum DC.and Lilium davidii var.The mutant plants were obtained by electrofusion of protoplasts and cell culture redifferentiation.The characters of the mutant plants were determined by bulblets culture,indoor vernalization and outdoor cultivation.The mutant plants propagated asexually and grew strong.The flowers were orange-red,the scales encircled tightly.It has strong resistance in drought and cold,tolerance to barren,and no obvious diseases and pests.Through more than three consecutive years of testing in Yan'an Baota District,Gaobai Mountain of Zichang City,Jiyi town of Yichuan County,it was found that the varieties had the characteristics of good stability,low hetero-plant rate and strong reflower ability.Through simplified genome analysis,'Yandan No.1'contained the genes of Lilium pumilum DC.and Lilium davidii var,and it is confirmed that a new variety of Lilium pumilum DC.was obtained throught cell fu-sion culture.
