The objective of present study was to assess seed yield and yield related traits of alfalfa clonal progenies. The phenotypic variation of traits within progenies was also determined. Eleven alfalfa clonal progenies of native origin were object of investigation. The experiment was carried out at the Experimental field of the IASS Obraztsov Chiflik, Rousse for three-year period. The traits plant seed yield (PSY), plant height (PH), generative stem number (GSN), inflorescence number (INP), pod number (PNI), seed number (SNP) and 1000-seed weight (TSW) were evaluated. There were statistically significant differences among clonal progenies for all studied traits. Five progenies (PM30, JM13, GM27, SL83 and PM18) were identified as very valuable genetic source with potential for developing high seed yielding varieties. There was established PSY, PNI and SNP exhibited moderate to high phenotypic variability within progenies, while PH and TSW expressed low variability. Data confirm possibility of used the traits number of pods per inflorescence and number of seeds per pod as criteria of germplasm selection for seed yield improvement.
