Department of Botany, SSJ Campus, Kumaun University, Almora, Uttarakhand – 263 601.
Correlations and path coefficients for 15 quantitative characters were estimated in 264 genotypes of wheat grown in the hills of Kumaun Himalayas at Vivekanand Parvatiya Krishi Anusandhan Sansthan, Almora. High positive correlations of grain yield/plant with days to 75% spike emergence, days to maturity, flag leaf length, flag leaf width, effective tillers/plant, spike length, number of spikelets/spike were observed. Path analysis indicated the importance of days to maturity, spike length number of grains/spike, biomass/plant, grain weight/spike, 1000-grain weight and number of spikelets/spike on grain yield suggesting using these characters for genetic improvement in wheat.
