ABSTRACT: We examined the influence of storage time on germinability and tube growth of freeze stored pollens collected from 25 wild male plants in Actinidia eriantha variety. Pollens were stored in freezer at -20°C for six months and one year periods to determine changing at germinability in time. In vitro germination was conducted in certain cultural medium defined for Actinidia genus. The results showed that the germination percentages and tube lengths of genotypes decreased at the end of storage period. MH22, MH45, MH47, MH56, MH67, MH70, MH71, MH72, MH74, MH55 and MH61 genotypes were evaluated as vigor genotypes, because they maintained their viability and germination capability displaying statistically insignificant decreasing although their tube lengths significantly decreased except MH67. This investigation provided to determine some robust wild male germplasm resources in A. eriantha in point of durability of pollens against long term conservation for using at future pollination and breeding programs.
