In order to elucidate the per se performance and selection strategies for development of high yielding varieties and/ or promising genotypes under organic condition, 12 varieties of barley were grown and evaluated for 10 metric traits during rabi 2015-16 at Experimental Area of Wheat and Barley Section of Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar. The analysis of variance indicated high significance of mean sum of squares due to treatments for all the traits studied. Three varieties viz., BH 946, BH 902 and DWRB 101 produced higher grain yield and also showed better performance for several other yield components. These genotypes can be used in barley improvement programme and will be helpful in breaking the yield plateau under organic field condition. Moderate to high heritability coupled with high genetic advance was revealed by grains per spike, grain yield per plot, peduncle length, spike length and plant height. Correlation analysis indicated highest significant positive correlation of grain yield per plot with biological yield per plot, followed by harvest index and days to maturity at both genotypic and phenotypic levels. Among all the traits, biological yield per plot, harvest index, spike length and peduncle length reflected positive direct effect on grain yield per plot. Therefore, to obtain high yield, one should consider these traits in barley breeding programme.
Key words:Barley, per se performance, genetic variability, organic condition
