COMPARATIVE STUDY OF SOME BARLEY GENOTYPES ON YIELD AND YIELD COMPONENTS UNDER NORTHERN IRAQI CONDITION

Abstract

This study was conducted on the farm of Agric. and Forestry College, Mosul Univ. for three seasons (2005-2006, 2006-2007, 2007-2008) to compare grain yield and it,s components of eight barley genotypes namely (Local black, Rehan, Jazeera (1), native white, Sameer and strains No.11, 21, 31) using RCBD with three replicates for evaluating the best one or more genotypes suitable under northern Iraqi condition. The result showed that the strain No.11gave higher number of spike/m2 for the three seasons. Significant increasing was detected in the number of grain/spike of each of jazeera (1) and strain No.31. The strains No. (21, 31) had the highest grain and straw yield and harvest index during each season and the cumulative of all seasons.
