 ABSTRACT

The experiment was carried out to assess the genetic variability, correlation and path coefficient analysis for 12 morphological and 6 physiological traits in 40 wheat accessions under normal sown irrigated conditions at CCS Haryana Agricultural University, Hisar during rabi 2018-19.Themean sum of squares due to genotypes were significant for all the morphological and physiological characters studied indicating thereby the prevalence of enough genetic variability in the materials under study. Phenotypic and genotypic coefficients of variation were highest for grain yield followed by biological yield, tillers per plant and plant height. High heritability coupled with high genetic advance reflected for grain yield, biological yield, plant height, peduncle length and tillers per plant, therefore, indicating the importance of these traits, which can be better utilized for crop improvement. Grain yield was significant and positively correlated with biological yield, harvest index, 1000 grain weight, grains per spike, tillers per plant, spike length, peduncle length, grain filling duration, NDVI1, NDVI2, SPAD1 and SPAD2; and significantly negative with days to heading, CT1 and CT2. Path coefficient analysis revealed highest positive direct effect of biological yield, harvest index, SPAD1 and SPAD2 on grain yield.Hence, due emphasis should be given to these attributes for genetic improvement of grain yield in wheat.

Key words: Genetic variability, Correlation, Path analysis, Wheat.
