Abstract

The new line (KAUZ/PASTOR//BAV92/RAYON CMSS00M02400S-030M-030WGY-030M-9M-0Y) (Gaboos cultivar) was evaluated at Gachsaran and Gonbad Agricultural Research Stations in the first time in 2006-2007. Due to optimum earliness, plant height, kernel weight and successful performance of grain yield in observation nursery, preliminary and advanced yield trials (2007-2009), this genotype along to 16 promised lines and check (Koohdasht cv.) studied during three years (2009-2012) in uniform regional wheat yield trials in Gachsaran, Khoram Abad, Gonbad and Ilam stations. Three years average of grain yield across all stations for new cultivar was 3514 kg/ha which showed significant difference at 5% probability level in compare to check (3333 kg/ha), and also, considered line had 17 and 11 percent grain yield increasing with significant preference at 5% and 1% probability level in Gachsaran and Gonbad stations respectively. In view of stability parameters, Gaboos cultivar had the best rank with low standard deviation and small within location coefficient of variation among all advanced lines. Koohdasht cultivar (check) had seventh rank with partially high standard deviation of rank, but, the least within location coefficient of variation. Mean while, it has good preference for qualitative characteristics particularly: protein percent, wet gluten, gluten index, water absorption, seed hardiness, zeleny number, sodium dodecyl solphat and bread volume in compare to check. New cultivar has not showed remarkable susceptibility to important current diseases such as yellow rust, brown rust, common bunt and Fusarim head blight in warm dry land stations under natural infection and artificial inoculation conditions.
