Abstract: 

In order to evaluate the economical and biological performance potential of hull-less barley genotypes, this experiment was carried out at Gonad Research Station during (2000-2001) crop year. In this experiment, fifteen hull-less barley genotypes and hulled barley (Hordeum vulgarevar. Turkmen) were evaluated in a simple lattice statistical design with two replications. Biological and economical performance, harvest index, yield components, plant height and the other agronomic traits were determined. Data analysis of variance showed significantly difference (P<0.01) within genotypes in the traits of economical performance, plant height, number spikes per square meter and kernels per spike. Also, there were significantly at difference 5% level in the traits of dry matter production before heading stage and 1000-Grain weight. The means were compared with Tukey's method showed that genotype No.13, with 536.3 g/m2 (7.3% more than check) and genotype No11, with 255.3 g.m2 (49% less than check) produced highest and lowest economical yield, respectively. The correlation between biological performance, harvest index, dry matter production before heading stage and kernels per spike with economical yield was positive and significant.
