Abstract

Aim: The study was conducted to estimate the correlation among the yield and yield contributing traits and their path analysis in barley in Randomize Block Design with 3 replications for 27 genotypes of barley.

Materials and Methods: Observations were recorded and analyzed based on quantitative characters viz; days to 50 % ear emergence, days to 75 % maturity, number of productive tillers per plant, spike length, number of grains per spike, biological yield per plant, 1000 grain weight, harvest index and grain yield per plant.

Results: Correlation and path analysis helped in determining the yield components. The grain yield per plant was found to be positively and significantly associated with number of grains per spike, biological yield per plant, number of tillers per plant, ear length and harvest index, whereas significantly and negatively associated with days to maturity.

Conclusion: It was concluded that high positive direct contributions to grain yield per plant was exhibited by grains per spike, harvest index, spike length and biological yield per plant and negative direct effect by days to maturity.
