Abstract

In order to examine and evaluate the variation and process of deterioration of accessions of FESTUCA OVINA seeds, which have been collected in natural resources genebank, research programs were carried out using 11 accessions. All of the accessions were examined in a complete randomized design with three replications under two different conditions, germinator and glasshouse. The recorded traits of the Germinator test included, SEED VIABILITY, SPEED OF GERMINATION and vigor index. The recorded traits of the test in glasshous, included germination persentage (G.P.), SPEED OF GERMINATION, plant height, number of tillers and root length in 40 days after planting.Significant differences found between accessions for all of the studied traits. Variation between accessions was significant in one or both of the environments. The results of correlation coefficient study had shown that negative correlation was found between reduction of SEED VIABILITY, SPEED OF GERMINATION and SEED VIGOR in germinator condition and G.P. and SPEED OF GERMINATION in glasshouse condition.Therefore, SEED DETERIORATION not only reduces SEED VIABILITY and G.P, but also decreases the SPEED OF GERMINATION and SEED VIGOR.In all of the FESTUCA OVINA accessions, because stored samples of each year were different from other years, therefore reduction of SEED VIABILITY, was highly affected by origin of accessions. It was not possible to differentiate between the effect of maintaining condition and origin of seed. It was suggested that, for better genebank management, accessions, have to be considered as regeneration unites of collected seeds.
