ABSTRACT
The paper identifies areas for the collection of germ
plasm, describes nursery techniques and presents results
on progeny and clonal trials of Populus ciliata Wall, in
Pakistan. Two-year-old seedlings of few individual trees
originating from xeric habitat outperformed those of
mesic habitat under high rainfall conditions. The
saplings raised at 1300m.atitude and under controlled
conditions exhibited better growth thus assign in early
screening of progenies/clones. The species can be easily propagated asexually and the application of hormone had
no significant effect on rooting. The narrow and
broad-sense heritability was low emphasizing the
importance of uniform site conditions and inclusion of a
large number of progenies and clones in test
plantations. These investigations suggest that a
suitable breeding strategy would further bring about
genetic improvement in Populus ciliata.
