Variability of some traits of walnuts (Juglans regia L.) in the test of half sib, originating in the Djerdap forest

As part of efforts for protection and restoration variability Juglans regia in Djerdap gorge, Serbia, where it grows as autochthonous relict species, the ten measured nine derived leaf morphometric parameters half-sib progenies Persian walnut originating from gorge was studied this work. According to contribution total expected variance, that were most effected by differences between are width (LW), side leaflet length (lL) top (20-30%). Using loadings with first four rotated principal components, describing 90.1% all grouped groups, LW, lL lt group, suggesting multicollinearity them. These had also relatively high canonical variable discriminant analysis. Only one them (lt) selected forward stepwise analysis, model achieved 26.5% correct allocation, while 62.4% allocation. Half-sib agglomerated three clusters, two small clusters originate trees close sheltered valleys tributaries river Danube, opposite mother cluster progenies, exposed dominant winds.
