Abstract: The present experiment entitled Study of yield attributing traits for identification of ideal wheat (Triticum spp.) genotypes for changing climate of Chhattisgarh was conducted at Department of Genetics and Plant Breeding, Indira Gandhi Krishi Vishwavidyalaya, Raipur during rabi 2009-10. Grain yield per plot showed highly significant positive correlation with biological yield at phenotypic level (0.704) and also at genotypic level (0.959). Ear head length showed highly significant positive correlation at phenotypic level with biological yield (0.605) and significant positive correlation with grain yield per plot (0.503). Number of tillers per plant exhibited significant positive correlation of both phenotypic and genotypic level with grain yield (0.492, 0.443), and biological yield (0.505, 0.441), respectively. Genotypes HI 8691, HI 1568, LOK 62 and GW 322 showed tolerance towards the higher temperature and gave higher yield in comparison to rest of the genotypes.
Keywords: Wheat, correlation coefficients, climate, Chhattisgarh
