'Echa 1' is the result of a successful breeding program conducted by the Fruit and Tea Research Institute of Hubei Academy of Agricultural Sciences from 1974 to 1992. This variety was created through a cross-breeding technique, with the female parent being 'Fuding Dabaicha' and the male parent being 'Meizhan'. The remarkable qualities of 'Echa 1' led to its recognition as a provincial variety by the Hubei Provincial Crop Variety Approval Committee in 1992. 'Echa 1' exhibits remarkable characteristics that contribute to its popularity. It demonstrates robust budding ability, vigorous growth, and rich content. The phenolic ammonia ratio of this variety is moderate, offering a balanced chemical profile. Notably, 'Echa 1' outperforms 'Fuding Dabaicha' significantly, boasting an average yield that surpasses its counterpart by an impressive 99.8%. Moreover, 'Echa 1' exhibits several advantageous traits, including stable genetic traits, high survival rates during transplantation, adaptability to various environments, rapid gardening, and a high reproduction coefficient. Additionally, the resistance of 'Echa 1' to cold, drought, and pests surpasses that of the 'Fuding Dabaicha' tea tree variety.
