In an experiment on genotype x environment interactions in tea (Camellia si
nensis, yield differed between the genotypes at all sites. The highest yiel
d in the third year after planting was 3760 kg ha(-1) for clone S15/10 at s
ite 4 (1800 m altitude), while the lowest was 1610 kg ha(-1) for clone 6/8
at site 1 (2200 m). The dry matter contents of harvested shoots from each c
lone ranged from 0.24 for clone TN14-3 down to 0.19 for clone S15/10. Yield
response to soil water deficits was more pronounced at site 4, where large
r deficits were observed. Hail damage affected the yield of two sites and a
temperature influence on recovery was evident.
