Correlation and path coefficient studies in barley (Hordeum vulgare L.) under dual purpose condition
Keywords: Barley, correlation, path coefficient, direct effect, grain yield
AbstractTwenty two barley genotypes were evaluated for green fodder yield, grain yield and related morphological characters. Plant height, spike length, number of spikelets per spike, number of grains per spike, number of tillers per meter row length and test weight had positive and significant correlation with green fodder yield. Spike length, number of spikelets per spike, number of grains per spike, number of tillers per meter row length, test weight and green fodder yield showed positive and significant association with grain yield. Number of tillers per meter row length and leaf length were having the highest positive direct effects on green fodder yield. Spike length, number of spikelets per spike, number of grains per spike, number of tillers per meter row length, leaf width, test weight, peduncle length and leaf length showed positive direct effects on grain yield. Hence these traits may be considered as selection indices for green fodder and grain yield.
