Abstract：Blueberries are rich in anthocyanins,vitamins,and trace elements,which can not only offer nutrints but also have various biological active functions to humen.Novel blueberry cultivars exhibit significant potential for applications in nutritional enhancement,pharmaceutical development,and sus-tainable agroecosystems.Liandazhixia(CNPVP 20200185)is a new blueberry variety selected by Da-lian Senmao Modern Agricultural Co.,Ltd.based on the selection of open pollination seedlings of Toro.In the spring of 2010,a total of 240 seedlings were raised at the Zhuanghe Experimental Base.In the spring of 2011,they were planted in a large experimental field located at the Dalian Senmao Modern Agricultural Co.,A promising strain was screened in 2013.The fruits of the new variety have consistent maturity,deep blue color,and good flavor,small and dry picking marks,high hardness(3.65 N),and uniform wax.It was propagated by tissue culture and cultivated for field trial in 2016.In July 2020,the it passed the substantive examination of the DUS test of the State Forestry and Grassland Administra-tion(SFGA),and in December 2020,it was granted the Certificate of Plant Variety Right of New Variet-ies issued by SFGA,and was finally named Liandazhixia.The tree has an upright growth habit with dark green leaves.The fruits are round in shape,with medium-sized and moist stem scars.The fruit flesh is firm and the berries are large,with an average single fruit mass of 3.48 g and a maximum mass of 4.09 g.The soluble solids content is 13.0％.The fruit is a bright blue color and medium-ripening.The pulp is sweet with low acidity,offering excellent flavor and high yield.This variety is suitable for both fresh consumption and processing purposes.It exhibited good resistance to diseases during the evaluation period.
