Phenotypic Stability, Adaptability and Productivity of Certain Clones of
Arborescent Willows

S um m a r y

Phenotypic stability, adaptability and productivity of 10 clones of Arborescent
Willows have been studied through five experiments. Regression analysis was
used. The processing of data for the stock volume (m´ha) was performed at the
age of 13 years of plantation.

On the basis of the regression coeffiecnt (b() and the average productivity
in all sites, the type of adaptability was defined for even.- single clone.
Among the tested clones some genotype differences were defined regarding
phenotype stability, productivity and type of adaptability.
According to the mentioned characteristics it was possible to divide the tested
clones into three groups:

1. Phenotypically very stable clones with low productivity and with specific
adaptability to unfavourable environment.
2. Medium stable clones of medium productivity and tendency to adapt to
all environments.
3. Phenotypically very unstable clones of high productivity with specific adaptability
to optimal environment.
Obtained results are very similar to those at the age of 5 years of plan
tation, for the same clones.
