[Variety Number]: Non-major Crop Variety Registration No.: GPD Tea Tree (2022)330013, Plant Variety Right No.: 20140085. [Variety Source]: Bred by Ningbo Golden Rhythm Tea Industry Technology Co. [Characteristics]: Shrub type, late-blooming species, upright posture, strong growth potential, low branching site, dense branching density; leaflets, leaf blade length 8.7 cm, width 3.2 cm, leaf blade narrow oval, apex shape obtuse, bearing state upward. Ningbo area spring tea bud one leaf period is generally in early April, bud two leaves in full bloom is generally in mid-April; light-sensitive yellowing tea, spring, summer, autumn and other seasons of the new shoots were yellow; germination density is high, less velvet hairs, buds are more slender, a bud of three-leaf length of 5.2 cm, the weight of one hundred buds 37.3 grams; full bloom for the second half of October to the middle of November each year. The biochemical sample of one bud and two leaves of spring tea contains 19.1% of tea polyphenols, 4.2% of amino acids, 3.6% of caffeine, and 47.3% of water leachate. Suitable for green tea. Baked green tea, yellow green, with white hair, soup color green and yellow bright, aroma is fresh and strong and more persistent, taste is strong and mellow, the bottom of the leaf is fine and tender into a flower, tender yellow and green and bright. The first growth cycle mu yield spring tea a bud and a leaf fresh leaves 24 kg, than the control 'golden bud' 11% increase in yield; the second growth cycle mu yield 37 kg, than the control 'golden bud' 1% increase in yield. Resistant to tea anthracnose, moderately resistant to tea leafhopper, strong cold resistance, strong drought resistance. [Suitable for cultivation area and cultivation technology points] suitable for Zhejiang, Jiangsu, Anhui, Guizhou area cultivation. It is recommended to choose relatively less light, relatively deep soil tea lot, in the fall or spring and other relatively abundant rainfall time planting; young tea garden should take to reduce sunshine, control the degree of yellowing cultivation measures; spring tea before as little as possible fertilizer, to prevent the yellowing of the new tops back to green.
