Overview

Longjing 43 is a national clone bred from Longjing population by Tea Research Institute of Chinese Academy of Agricultural Sciences. It is suitable to be planted in Jiangbei and Jiangnan tea producing areas

Its tea is characterized by elegant appearance, flat and smooth, light green color, lasting fragrance and mellow taste. It is suitable for making black tea and green tea, especially flat famous green tea. It is suitable for planting in the middle and lower reaches of the Yangtze River. The biggest characteristic is that it has strong ability to grow buds, germinate early, germinate orderly and has high density.

It has described the sequencing, assembly, and analysis of a high-quality chromosome-scale tea genome, along with the directions of divergent selection in the CSS and CSA populations, and conduct phylogenetic analysis of tea accessions. However, details regarding the origin of tea and the subsequent routes of expansion remain to be clarified.
