Abstract

To evaluation the ADAPTABILITY and yield stability of dryland BARLEY lines at tropical and sub-tropical dryland areas this study was performed with 20 BARLEY genotypes in RCBD for three growing season (2002-2003 to 2004-2005) at 3 tropical and sub-tropical dryland areas. Bartelet and Hartly Fmax tests were used for detecting homogenity of error variances. Result showed that error variance for all of expriments were hemogenous at 5 and 1% probability levels. To estimation of stability and adatability grain yield of lines, Lin and Binns method (intra location variance), regresion indexes, deviation from regresion, coffiecient of location variation, coffiecient of determination (R2), and non-parametric methods such as rank and standard deviation of rank (SDR) were used. Result of combined analysis of 3 years and 3 location showed that the effects of line, line × year and line × year × location were significant at 1% probability level, while the other effects were not significant. The lines of 13, 12, 16 and 17 have the highest grain yield (3.889, 3.776, 3.763 and 3.545 t/ha, respectively). Results of stability analysis indicated that the line of 13 had higher mean rank for grain yield and in respect of standard deviation of rank line of 1 had lower SDR (2.59) followed by line of 13 (2.74). in respect of environmental variance and environmental cofieceint variation lines No. 2 and 14 detected with the at least amounts 0.36 and 19.5% respectevely. In comparing all of lines about stability parameters, lines No. 13, 16 and 17 recognized as the the best lines and finnally line 13 as the new BARLEY line that now introduced namely mahoor.
