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