Correlation Analysis of Grain Yield and Important Agronomic Traits in Six Rowed Barley (HORDEUM VULGARE L.) in Agra Region

Dr. Rajiv Kumar Singh Rathore | Dr. Yashasvita Chauhan

Abstract: The investigation was conducted to evaluate the genotypic and phenotypic correlation analysis of grain yield and other contributing traits of cultivars and breeding line of barley in K. V. K. Research Farm Mathura. The results of correlation coefficient revealed thatthe genotypic correlations in general were higher than phenotypic correlations. The seed yield expressed significant and positive correlation at genotypic and phenotypic levels with tillers per plant (r= 0.382G, r= 0.358P), seeds per spike (r= 0.583G, r= 0.519P), 1000 seed weight (r= 0.364G, r=0.297P), biological yield per plant (r= 0.921G, r= 0.862P) and harvest index (r= 0.498G, r= 0.439P). Seed yield exhibited positive but non-significant association with days to flower (r= 0.058G, r= 0.029P) and strongly significant negative association with days to maturity (r= -0.634G, r= -0.487P) and plant height (r= -0.083G, r= -0.075P).
