[Variety No.] Non-major crop variety registration No.: GPD Tea Tree (2021)350013. former Fujian Provincial Crop Variety Validation Committee Validation No.: Min Validation Tea 2000002. [Variety Source] Fujian Provincial Academy of Agricultural Sciences, Tea Research Institute of Fujian Province, from the 'Dahongpao (tea)' natural hybrid progeny from a single plant selection. [Characteristics] Shrub type, late-blooming species, strong growth potential, half-open posture, medium leaf type, leaf length 8.2 cm, width 3.6 cm, leaf blade medium oval, leaf insertion state upward. In Fujian Min Dong area spring tea bud two leaves bloom in mid-April, the new buds and leaves dark green, less velvet, a bud of three leaves 9.9 centimeters long, one hundred buds weighing 83.0 grams. Spring tea bud two leaves biochemical samples containing tea polyphenols 35.5%, amino acids 4.3%, caffeine 3.3%, water leachate 46.5%. Suitable for oolong tea. Oolong tea, heavy and solid appearance, color oolong, aroma, long, floral, taste mellow and smooth, resistant to brewing. The first growth cycle of spring mu yield bud three leaves 540 kg of fresh leaves, than the control 'Huangdan' yield increase of 125%; the second growth cycle of spring mu yield bud three leaves 768 kg of fresh leaves, than the control 'Huangdan' yield increase of 62%. It is moderately resistant to tea leafhopper, tea weevil and tea moth, moderately resistant to tea anthracnose, and moderately resistant to cold and drought. [Suitable for planting area and cultivation technology] Suitable for spring and fall planting in Fujian Quanzhou, Ningde tea area. It is recommended to cultivate strong seedlings, adequate fertilizer, double rows and double columns of cross planting, mu planting seedlings about 4000, young age annual fixed shear 1-2 times. When mining, pay attention to leave the leaves to pick, picking and raising combined, to promote the sprouting of buds, can be formed early high-yield canopy. After the garden to strengthen fertilizer management, more organic fertilizer, can improve the quality of oolong tea, give full play to its high-yield characteristics.
