| Abstract:
Olive trees are vegetatively propagated and little information is available on their sexual propagation. Olive seeds do not germinate promptly under favorable conditions mainly due to restrictions imposed by tissues surrounding the embryo. The objectives of our study were to compare the germination capacity of seeds of cvs Kalamon, Amphissis, Koroneiki, Chalkidikis and Manzanillo and to assess the growth traits of the seedlings derived from these seeds. The experimental material was divided into two groups: The first group consisted of olive seeds from selfing cv. Kalamon and from crosses Kalamon x Amphissis and Kalamon x Koroneiki. The second group consisted of seeds from open pollination of the cvs Kalamon, Amphissis, Koroneiki, Chalkidikis and Manzanillo. Data were recorded for the percentage of seed germination, the number of days to final germination, and the height and leaf number of the seedlings. The germinability of the seeds and the seedling growth traits revealed the general and specific combining ability effects of the tested cultivars, helping in the assessment of their genetic background and potential. | |
