Study Of Several Traits Related To Productivity In Lines Of Winter Feed Barley

Abstract

The study was conducted in the period 2006-2008 in the experimental field of the Institute of Agriculture, Karnobat. The aim of this study was to assess the of yield related traits of 16 lines of winter feed barley (8 from var. pallidum and 8 from var. parallelum). According to variance analyses, spike length was less affected by the weather conditions and was determined mainly by the genotype. Plant height, number of fertile tillers per plant, grain number per a spike, sterile spikelet number per a spike, grain weight per a plant and 1000 grains weight were more affected by the weather conditions of a particular year. Hence, these traits could not be considered as suitable selection criteria for the development of high yielding feed barley genotypes. Differences were observed among the var. pallidum and var. parallelum regarding the traits studied
