VARIABILITY AND HERITABILITY OF THE HEIGHTS AND NUMBERS
OF BRANCHES IN WHITE WILLOW (Salix alba L.) POPULATIONS
AT BAKOVCI AND LIPOVLJANI


Summary


Pei formed were investigations into the variability and heritability of stem
heights and number of branches within two grown-up populations of White Willow
(Salix alba L.) the one at Bakovci (Drava River), the other at Lipovljani (Sava
River), also in one-year-old and two-year-old generative progenies descending from
the mentione´d populations. Generatve progeny from the Bakovci population was
raised from the seed obtained through free pollination and collected from four
mother trees, while in the Lipovljani population the seed was collected and the
plants raised from six mother trees. Seedlings were raised under the same ecological
conditions and tending measures.


Data concerning the stem heights and number of branches in grown-up Bakovci
and Lipovljani populations, and in their generative progenies were statistically processed
(Tabs. 1 and 2) and are graphically represented (Graphs 1 and 3). Heritability
