بررسی عملکرد دانه و خصوصیات زراعی ارقام و لاینهای جو بدون پوشینه در آزمایشات بین المللی مقایسه عملکرد در مناطق گرمسیر و نیمه گرمسیر دیم

This study was conducted by 136 international naked barley genotypes using one experiment of INBON that was performed systematically ant without replication with Mahoor as check Trial was performed at 2 stations (Gachsaran and Lorestan) during one year (2009-2010) and each genotype was planted in a 2 rows, 25 cm line spacimg and 2 meters length. During growth session, data was collected from some important morpho- physiological traits and all of genotypes were compared with mahoor as check. Present report was prepared as territorial report for Gachsaran station. Results indicated showed that grain yield was ranged from 420 kg/ha to 3850 kg/ha for lines 78 and 89 respectively. Line 89 HIGO/LINO/5/ABETO//GLORIABAR/COME/3/SEN /4/MJA/6/PETUNIA 1/5/POST/COPAL//GLORIA-BAR/COME/3/SIND89A- 148/4/CARDO/7/PEREGRIN CBSS01Y00815T-D-0Y-4M-1M-1Y-0M had 189.5% increment relation to mahoor was located in the first rank. Line 121 GAL/PI6384//ESC.II.72.607.1E.4E.5E/3/QUINA/4/BARKE CBSS01M00653T- 0TOPY-4M-2Y-1M-1Y-0M with 3400 kg/ha grain yield and 71.7% increment relation to mahoor was located in the 2nd rank. Lines No. 33, 88 and 45 with 3340kg/ha, 3030kg/ha and 3000 kg/ha and 129.6%, 127.8% and 106.2% yield increment relation to mahoo are located in the 3rd, 4th and 5th ranks. Finally, were selected 25 naked barley genotyped in order to more investigation for the next year.
