✦ Synopsis
Pollen from the inbred maize line HMv 1645 was used to study the effect of pollen treatments (drying and deep-freezing) on the phenotypic performance of the next generation . Fresh and artificially dried pollen samples with different water contents (56%,18%,13% and 10%) were used for sib pollinations immediately after collection or drying . Samples containing low amounts of water were then stored in liquid nitrogen for 7 days . Fertilization ability of the samples with 13% water was the highest after storage . Plant characteristics of the next generation originated from the seeds set by differently treated (fresh, dried to 13% water and deep-frozen) pollen were examined and statistically analysed . Pollen treatments due to the pollen storage procedure did not cause detectable changes in quantitative characters of the next generation .
