Developing climate resilient Salix clones through control breeding

Published on

Over the years, two hundred clones/strains/species of
Salix were introduced from different countries and raised
in the germplasm bank.The best clones after nursery and
field screening were selected for control crossing using
Line × Tester design with 8 parents to develop superior
hybrids.The F1 populations of the successful crosses were
raised in the nursery in uniform environment to study the
extent and pattern of variation in growth and morphometric
characters. In case of overall performance PN-227 × NZ-
1140, J-799 × S. tetrasperma, PN-227 × J-795 and J-799 ×
Austree hybrid progenies were found outstanding for most
of the growth and morphometric traits. High heritability
and genetic gain were recorded for plant height followed
by number of leaves and branches. The superior hybrids
after further field evaluation and parental verification will
be commercially released covering wider climatic range
from tropical to temperate regions of the country.
