Abstract: Phyllanthus emblica L. is one of important fruit trees with both medicinal and edible values. Currently, fresh variety of P. emblica has high economic benefit and great development potential. Herein, Lütianyougan, a new table variety of P. emblica with excellent traits, was selected from the wild seeding. In 2013, a native population of P. emblica with different traits was first discovered in Hekou Town, Lühe County, Shanwei City. After many years of field investigation and quality analysis, the fruits from a single plant line, which was named as No.2 tree, was found to be bigger than other varieties, and had strong aftertaste and light astringent. Due to its high quality and great potential in the market, No.2 tree was grafted on wild seeding rootstock for further field trials in 2014. Through 3 generations of continuous observation on the growth and fruiting habits of grafted seedlings, No.2 tree showed stable economic characteristics and high-yield performance with good fruit quality, and its genetic stability was confirmed by inter simple sequence repeat (ISSR) analysis. In 2018-2021, the regional trials were carried out in three different cities including Shanwei, Jieyang and Shantou, and the growth and fruiting habits of No.2 tree were stable with good performance. In November 2023, it was released as Lütianyougan with the registration code of Yuepingguo 20230009 after the validation by the Guangdong Provincial Crop Variety Examination and Approval Committee. Lütianyougan is a fresh eating variety of P. emblica. The tree vigor is strong with erect shape. The color of bark is gray-brown, the old branches is offwhite with round-punctiform pores, while the new shoot is slender with dense longitudinal textures. The leaf is imparipinnate, young leaf is yellow-green, and mature leaf is dark green, leathery, and rectangular shape. The flowers are white with six petals. The inflorescence of Lütianyougan is cymes composed of many male flowers and one female flowers or all male flowers. The fruit is oblate and smooth with visible ribs, the peel of immature fruit is blueish-green while the peel of mature fruit is yellowish-green, the pulp is light-green, crisp and slagging, with strong aftertaste, and its astringent is light. The single fruit weight was 11.0 g, with the maximum of 17.34 g. The fruit shape index was 0.78, and the edible rate was 92.6%. The soluble solid content is 9.44%, the total sugar content is 7.2 g·100 g-1, the titrable acid content is 10.81 g·kg-1, and the vitamin C content is 294.0 mg·100 g-1. In Chaoshan area of Guangdong, the fruit ripens from early October to early November, belonging to the late-maturing variety type. The maturity and fruiting period were long, and the physiological fruit drop was not obvious. It has large fruit, high yield, good marketability and strong adaptability. Due to highly easy to manage and cultivate, it is suitable for cultivation in Guangdong and similar climate areas.
