Identification Methods and Technical Key Points for Tea Plant Breeding Materials
Observe the traits of breeding materials, analyze the characteristics and features of various variant materials, select the superior and eliminate the inferior according to breeding objectives, and finally develop new varieties through comparative trials. The identification content is divided into 3 aspects: yield traits, quality traits and resistance. The yield traits of tea plants are mainly reflected in sprouting density and bud-leaf weight, growth speed, length of growth period, regeneration capacity after picking, and recovery capacity after suffering disasters or wounds; quality traits are mainly reflected in the chemical composition, color, pubescence,
