STABILITY FOR YIELD IN SEED STOCKS AND CLONES OF TEA (CAMELLIA SINENSIS L.)

Published on

Stability for yield o(made tea was studied in 13 Fl hybrid genotypes (seed stocks) in five
environments. Genotype, year (linear and non-linear) and genotype x year (non-linear)
interaction effects were highly significant. But genotype xyear (linear) interaction was not
significant. The genotype St. 462 was most stable for yield amongst all genotypes. It can be
used in breeding as stable and heterotic hybrid. In another trial, stability for yield of made
tea was examined in 11 diverse tea genotypes (dones) in five environments. Genotypes,
years and genotype x year (G x E) interaction effects were highly significant. G XE (linear)
effect was highly significant indicating thereby possibilities of prediction of yield
performance over years. Significant pooled deviations showed that variation in yield of
genotypes was influenced by unpredictable factors as well. Three genotypes namely, Nil
PF 3/14, 480/13 and Tinga GH 3/18 were most stable coupled with medium yield
performance. These genotypes could be used in future tea breeding programmes for yield
improvement.
