Abstract

The agronomy, made tea quality, chemical components, cold resistance of 200 accessions of tea germplasms were investigated during 1996-2000. Among six accessions of elite tea germplasms, their made tea quality exceeded national clones, four with high polyphenol content (>38%), six with high caffeine content (>5.2%) and two with low caffeine content (<1%) germplasms were selected. Based on the studies of RAPD marker, isozyme and pollen morphology, the heredity of tea germplasms and their cutting offsprings was basically stable.
