This study was conducted for three years (2002-2004) in a black pine seed orchard established with 30 clones
originating from the forest of Yenice-Bakraz in Bartın, 1990. During the research, the variations between the
clones in the seed orchard were determined based on the number of male and female flowers. According to the
results, the average values of flower production in three years at seed orchard showed considerable variations. It
was determined that the number of the male and female flowers were 817,2 and 99,3 respectively. 62% of
average number of male flowers and 49% of female flowers were produced by 10 clones in 3 years. It was also
determined that the amount of the flowers for the clones showed significant differences within the years.
