Qiancha 1

【Overview】Qiancha1 is a tea clone of shrub, medium leaf and early sprouting, which was bred from the ‘Meitantaicha’ using the single plant breeding method by the Tea Research Institute of Guizhou Academy of Agricultural Sciences. From 2003 to 2013, the compare appraisement test and regional adaptability test of ‘Qiancha1’ were carried out in Guiyang, Meitan, Xingren and other places, and the results showed that compared with the control "Fudingdabaicha", 'Qiancha no. 1' had a higher survival rate, stronger growth potential, higher yield and better tea quality. The average survival rate of multi-site transplanting was over 99%, 3 percentage points higher than the control. After two years of planting, the height and width of the canopy were 51.3cm and 78.6cm, respectively, 16.8cm and 30.1cm higher than those of the control. The yield of fresh leaves of spring tea was 21.6% higher than that of the control. Suitable for green tea, black tea and white tea. In 2016, it was authorized by the Ministry of Agriculture and Rural Affairs of the People’s Republic of China to protect new plant varieties (variety right No. : CNA20080571.1). In 2019, it was granted the registration certificate of non-major crop varieties (Certificate No.: GPD tea plant (2019) 520007) by the Ministry of Agriculture and Rural Affairs of the People’s Republic of China. 【Characteristics】Tree: Open; Branch density: Dense; Leaf morphology: Slightly oblique; Leaf length: 10.3 cm; Leaf width: 4.3 cm; Leaf shape: Oval; Leaf color: Green; Leaf surface: Micro uplift; Leaf opex: Taper; Leaf base: Wedge; Leaf margin: Micro fold type; Leaf lamina: Soft; Corolla diameter: 3.9 cm; Sepals number: 5; Petals number: 6.

[Variety Number] Non-major Crop Variety Registration No. GPD Tea Tree (2019)520007,Plant Variety Right No. CNA20080571.1. [Variety Source] Selected by Guizhou Tea Research Institute from single plant selection and asexual cuttings of 'Meitan Moss Tea'. [Characteristics and properties]: Shrubby, medium-leaved, early-blooming, open posture. Leaf length 10.3 cm, width 4.3 cm, leaf blade oval, leaf blade slightly upward oblique bearing, leaf color green, leaf surface slightly rumble, leaf body slightly dorsal roll. In Guizhou Meitan area spring tea bud two leaves period in late March, a bud three leaves length 7.1 cm, 100 buds weight 51.2 grams, the new buds and leaves yellowish-green, velvet hairs medium, buds fat, holding tenderness strong. The biochemical sample of one bud and two leaves in spring contains 17.3% tea polyphenols, 4.2% amino acids, 3.8% caffeine, 45.1% water leachate. Suitable for green tea and black tea. Baked green tea, curly shape, tight rope, green phi hair, soup color tender yellow and bright, aroma of flowers, taste fresh, sweet and smooth, the bottom of the leaf green and bright buds; black tea, curly shape, tight rope, showing the golden milliard, black and brown, soup color red and bright, aroma fresh, sweet and mellow, the bottom of the leaf is soft and even with buds, more red and bright. The first growth cycle mu yield of one bud and two leaves 212 kg of fresh leaves, than the control 'Fuding large white tea' 25% increase in yield; the second growth cycle mu yield of one bud and two leaves 235 kg of fresh leaves, than the control 'Fuding large white tea' 19% increase in yield. It is susceptible to tea leafhopper and tea stick thrips. [Suitable for planting area and cultivation technology points] Suitable for winter planting in the ecological zone of Guizhou at an altitude of 400-1800 meters.
