| Abstract: | The results of this study indicated a great deal of genetic variation in a number of characters of horticultural interest
in kiwifruit seedling populations, and therefore, a potential to improve kiwifruit by vine selection. High narrow sense heritability
was shown for pedicel length(0.62) and flowering duration (0.50) in male vines, and pedicel length (0.67),floral shoot percentage
(0.54), leaf length-width ratio (0.64), fruit elongation (0.64) and fruit weight (0.52) in female vines. For these traits,
selection of superior seedlings should lead to rapid genetic improvement in these populations.
