Correlation coefficient and path coefficient analysis in some quantitative trait’s in bread wheat [Triticum aestivum (L.)]

Abstract

Twenty genotype of wheat were evaluated in Randomized Block Design (RDB) with three replication for yield and its contributing traits during Rabi 2016-2017 find out correlation coefficient and path coefficient analysis. Grain yield had a highly positive and significant genotypic correlation with days to 50% flowering, days to maturity, number of effective tillers per plant, spike length, number of seed per spike, biological yield per plant and harvest index, and 1000-grain weight showed positive correlation with grain yield in both (E1 & E2) conditions while grain yield had positive and significant correlation with days to 50% flowering, number of effective tillers per plant, biological yield per plant, 1000-grain weight and harvest index in both (E1 & E2) conditions. Path coefficient at genotypic recorded that biological yield per plant had highest direct positive effect on grain yield per plant followed by harvest index, days to 50% flowering, number of spikelets per spike, days to maturity and plant height in both (E1 & E2) conditions while path coefficient at phenotypic recorded highest direct positive effect on grain yield with biological yield per plant followed by harvest index, number of spikelets per spike, days to 50% flowering and 1000-grain weight in both (E1 & E2) conditions.
