conduction of test for accelerated aging of seeds of maize collection accessions allows determination of their storage potential (SP) that is a very important complex characteristic when placing seed material for longterm storage in plant gene bank (ex situ conservation). Based on morphophysiological and biochemical parameters of seeds and seedlings, ranking of genotypes was performed taking into account their potential capability of maintaining viability after the influence of stress factors during the process of accelerated aging (increased temperature – 42-44оC and increased humidity – 90-100%). With the help of storage potential of seeds it is also possible to estimate the terms of reproduction of valuable selection material.
