SUMMARY
An experiment was conducted to test the performance of different advance barley genotypes for grain yield and its components under saline soil condition at Barley Research Area, Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar during rabi 2018-19. The experiment was laid in randomized block design with three replications with a plot size of 6.9 m2. Sixteen advance barley genotypes along with two national checks viz., RD 2794 and BH 946 were evaluated on a natural soil salinity patch having pH of 8.3 and Ece 6 dsm-1. The variation due to treatment were found to be highly significant for days to heading, plant height, spike length, number of tillers per meter, number of grains per spike, 1000 grain weight (g), biological yield and grain yield, and significant for days to maturity and harvest index. The coefficient of variation was recorded highest for grain yield (17.40) followed by harvest index (11.88) and biological yield (8.36); however, days to maturity (1.52) exhibited lowest variation. Six genotypes namely BH 17-26, BH 17-32, BH 16-44, BH 17-34, BH 17-35 and BH 16-35 produced higher grain yield and also showed better performance for several other yield components. These best performing genotypes may be considered in future breeding programmes intended to develop salt tolerant varieties.
