Variation analysis and quantitative trait loci mapping of 16 free amino acid traits in the tea plant (Camellia sinensis).

ABSTRACT:

Background

The levels of free amino acids (FAAs) and the timing of bud flush (TBF) are among the the most economic traits of tea plants (Camellia sinensis). Investigating the genetic variation characteristics of FAAs and their potential associations with TBF is critical for the breeding of new tea cultivars with high economic value.

Methods

In this study, we utilized the 'Emei Wenchun' (♀) × 'Chuanmu 217' (♂) filial 1 (F₁) genetic population (n = 208) and measured their FAA contents in the "one bud and two leaves" samples across two spring seasons and one summer season using high-performance liquid chromatography combined with the Waters AccQ-Tag method. The sprouting index (SPI) was observed over two springs to quantify the TBF trait. A genetic map previously con
