 Abstract

The aim of this study was to investigate the main morphologic and biometric parameters, and the production index, in 20 wheat accessions (Triticum aestivum L.), from the base collection of the Gene Bank in Albania. The studied morphological parameters were: plant height (PH), spikelet for spike (SS), grain weight per spike (GWS), spike weight (SW), 1000 grain weight, days to maturity (DM). Collected data indicated that genotypes present significant differences for PH; the number of SS, there is a high difference of GWS (g per spike). High differences were presented for days to maturity (DM). Also some genotypes have high protein content (12-15.2%) and the gluten content with an average 21.6-35.6 %. Results taken were analyzed for relations between characters in wheat genotypes. Hierarchical Cluster Method was used to observe relation and distance among genotypes. The collected data by this study will be as additional information for Gene Bank and to be used in the plant improvement programs.
