Association studies of yield and it’s attributing traits in indigenous and exotic Barley (Hordeum vulgare L.) germplasm

Abstract

The present study comprising of 101 barley genotypes was carried out at deportment of Genetics and Plant Breeding, BHU during rabi of 2016-17. Correlation and path analysis was carried considering traits viz., days to 50% flowering, days to maturity, flag leaf length, effective tillers per plants, SPAD value, stomatal conductivity, proline concentration, spike length with awn, spike length without awn, plant height, grain per ear, 1000 grain weight and grain yield per plant. Characters viz., grains per ear, plant height, 1000 grain weight, days to maturity, stomatal conductivity and spike length found highly significant and positive correlation with yield which indicated strong association of these traits with the yield. Path coefficient analysis suggested that spike length, plant height, grains per ear, 1000 grain weight had positive direct effects on yield per plant.
