Abstract
BACKGROUND
Cryo-preservation of plant materials in liquid nitrogen (LN) has been described as a suitable technology to conserve genetic resources of several species. However, the potential effects of LN in the subsequent plant growth in the field should be studied before large-scale implementation of cryopreserved germplasm banks.
OBJECTIVE
To describe the field performance of cryopreserved seed-derived maize adult plants.
MATERIALS AND METHODS
Germination percentage and numbers of leaves and ears per plant, internodes in stems, middle - aged leaf length, plant height, ear traits and weight of 100 seeds were recorded.
RESULTS
Statistically significant differences between adult plants derived from cryopreserved seeds and the control treatment were not observed (t-test, p=0.05).
CONCLUSION
The results presented confirm at the phenotype level the effectiveness of maize seed cryostorage to preserve and regenerate true-to-type plants.
