The objective of this study was to assess performance variability between farmers’ and improved varieties of barley for yield and yield related traits and seed quality attribute. Seven Farmer’s varieties (FVs’) and three improved varieties were tested at three locations and three replications by RCBD design during 2010 cropping season. Seed quality test was conducted as per International Seed Testing Association standard. Data were subjected to analysis of variance using software SAS version 9. Treatment means were separated using Duncan’s Multiple Range Test (DMRT). Relatively G/gurrachaa was superior in yield potential and seed quality traits. The analytical purity analysis tests were ≥ 98.17% physically pure which was greater than 85% of the national standard. Barley seed exhibited dormancy and germinated poorly. Varieties showed seed dormancy break after-ripening. The presence and type of fungi were determined according to their development on seed. Accordingly, out of sixteen different fungi genera identified, eight were known to be seed transmitted and the rest were seed deteriorating fungi. Significant different was observed among varieties for pathogen infection. The study indicated that greater yield response could be obtained through direct selection scheme in FVs’. Minimum improvement should be vital for adopting early maturing varieties in an area of short rainfall so as to attain food security. Varieties differ in dormancy duration. Hence, dormancy behavior of the genotypes needs to be studied.
