بررسی عملکرد دانه و خصوصیات زراعی ارقام و لاین های جو بدون پوشینه در آزمایشات مشاهده ای مقایسه عملکرد در مناطق گرمسیر و نیمه گرمسیر دیم

This study was performed with 56 hulless barley genotypes contain 2 experiments in 2 stations for warm and semi warm dryland areas of IRAN (Khorram abad , Gachsaran) at 2008-2009. In the barley observation experiments , each genotypes was planted in 6 rows with 6 meters length and spacing 20 centimeters in both stations (Khorram and Gachsaran). During the growing season and after harvest , data were collected from some agronomical and morpho-physiological traits such as , DHE , DMA , TKW , grain yield , reaction to diseases and drought. As the result generally 23 genotypes that posses good agronomic traits and yielded more than check were selected.
