Genetic variation in Anatolian black pine (Pinus nigra Arn. subsp. pallasiana. (Lamb.) Holmboe.) populations in Turkey.
The present study was carried out in a progeny trial established by ten population of Anatolian black pine [Pinus nigra Arn. subsp. pallasiana (Lamb.) Holmboe.] to estimate genetic variation, heritability, genetic gain and also genetic and phenotypic correlations among the characters based on 9th year results of tree height and branch characters in the trial. Average tree height was 112.7 cm in polled population, while average of branch characters were generally similar. The results of ANOVA showed statistically significant difference (0.05>p) among the population for characters. Family x population interaction was also found statistically significant. Variation among family was lower than that of within families for the characters. Family mean heritability (0.65 < h(f)²) was higher than individual heritability (0.42 < h(i)²) for the characters. Genetic variation among population showed low ratio in total variation, while it was very high among and within the families. It emphasized importance of individual selection in breeding programme. Phenotypic correlation was statistically significant between tree height and branch diameter only. It was also highest in genotypic correlation (r = 0.81).
