Title : THE DIVERSITY OF GENETIC RESOURCES IN THE ALBANIAN OLIVE
Abstract : This study for the diversity, were evaluated the genetic variation of 56 autochthonous olive genotypes Olea europaea L from Albania. Morphological marker based analysis were performed for olive identity characterization, to determine their localization, and usage limits. The description was done for each olive genotype, of 49 characteristics of tree, leaf; inflorescence, fruit and endocarp were measured during the study. Analysis of variance verified the morphological, technological and physiological distances and showed cultivar classification. Principal component analysis (PCA) was used to compare fruit, pit, leaf and growth habit characteristics between olive resources. Basing on the endocarp characteristics, as an important morphological marker, olive cultivars are clustered in seven groups. According to the oil content, genotypes are clustered in three main groups in low, medium and high oil content. Some of fruit and endocarp features (D, d, D/d, T/E, weight) were highly related to the oil content (R²=0.871). In general, clustering of cultivars would suggest the existence of a strictly related genetic base with little morphological differences. The diversity is classified in two centre (i) South-West, with diversity and richness coefficient of 3.45 & 89 (ii) Central-West, with 1.41 & 65. Morphological analyses of 56 genotypes hold up the hypothesis for the autochthonous origin of olive resources and in this respect the hypothesis on the evolutionary history of the olive in Albania.
