Abstract The influence of nine Actinidia deliciosa (A.
Chev.) C.F. Liang et A.R. Ferguson var. deliciosa rootstocks and four
`Hayward' strains on the growth and cropping performance of kiwifruit vines 4,
5, and 6 years after grafting was determined. Canonical discriminant analysis
was effective in summarising the complex relationships of the data,
distinguishing among rootstocks and `Hayward' selections on the basis of field
performance. Plants grafted on rootstock 4 (male) were distinctive and
characterised by strong trunk growth and large fruit size over the three
seasons. In contrast, scions on the female rootstocks 7 and 9 were less
productive in the second and third seasons. Ungrafted own-rooted vines had high
yield in two seasons. `Hayward' A as a scion achieved the best field
performance in yield and fruit sizing across eight root systems in two seasons.
Vines grafted with `Hayward' B showed low productivity.
