Rezumat

Seed storage potential (SP) is an important complex indicator characterizing the ability of collection samples to be conserved ex situ in a genetic bank. The accelerated aging test (AA test) was used to determine the storage potential of maize samples. The AA test for maize seeds was carried out at 43-44°C, 90-100% relative humidity, with an aging time of 96 hours. After the test, various morphophysiological parameters were determined on 8 collection maize samples: germination energy and seed germination, root length and quantity, wet and dry root biomass. The maize genotypes were divided into 3 groups according to various post-test indicators: group 1 (high SP) – genotypes P235; P 310; P243; group 2 (medium SP) – genotypes Р 402, Р 383, Р 465; group 3 (low SP) - genotypes Р 461 и Р 427. Thus, the use of AA test on maize collection samples based on morphophysiological characteristics allows gradation of genotypes by seed SP.
