Abstract
The aim of this study was to assess the agronomic characteristics of common wheat (Triticum aestivum L.) germplasm, maintained in ex situ collection at Plant Genetic Resources Institute (PGRI), Agricultural University of Tirana. Total of 100 wheat accessions were planted under field condition and their agro morphological characters (14 quantitative traits) such us, plant height, spike length, 100 kernel weight, days to maturity were recorded. The results show that the highest value of plant height trait was recorded in AGB 0150 accession (167 cm), meanwhile two accession recorded the highest number of spikelet per spike ±25.8 ( AGB 0013 and AGB 0138). Positive correlation are observed among descriptors, as number of kernel per spike and kernel weight trait (r=0.85), also data show positive relation (r=0.529) between spike length and number of spikelet for spike. The divergence between accessions was observed using Cluster analyze. The accessions were gathered in 6 major groups (cluster 5 with 38 accessions and cluster 2 with 27 accessions). Based on this analyse accessions in cluster 2 and 5 were the nearest neighbour with the lowest divergence levels meanwhile wheat genotype grouped in cluster 3 and 4 presented the farthest one.
