Title: Variability and Path Coefficient Analysis of Yield Components in 'Oblacinska' Sour Cherry Sub-Clones
Authors: V. Rakonjac, D. Nikolic
Abstract:
The present paper examines variability of initial fruit set, final fruit set, number of flower buds/cm2 limb
cross-sectional area, number of flowers/cm2 limb cross-sectional area, number of flowers per bud, fruit weight and
yield in 10 selected sub-clones of ‘Oblačinska’ sour cherry (Prunus cerasus L.). Correlation and path coefficient
analysis indicated both direct and indirect effects of yield components on yield.
Sub-clones of ‘Oblačinska’ sour
cherry differed significantly in all characteristics studied.
Genetic variance was found to be a dominant component
of yield variability, whereas year had the greatest effect on variability of the majority of yield components, except
for number of flower buds/cm2 limb cross-sectional area.
Correlation analysis showed that only fruit weight was
correlated significantly with yield.
However, apart from fruit weight, initial fruit set and the number of flowers per
bud were isolated by path analysis as other important yield components.
