Abstract
The present experiment entitled “Genetic variability, Correlation and Path analysis for yield and yield components in F6 generation of wheat (Triticum aestivum L.Em. Thell.)” Was conducted in Rabi 2015-16 at the Field Experimentation Centre of the Department of Genetics and Plant Breeding, SHUATS, Allahabad. The experiment was carried out in augmented design with three (3) blocks to obtain information on estimates of variability, correlation coefficient and path analysis among 19 genotypes of wheat. Analysis of variance revealed that there was significant differences among all the genotypes. On the basis of Per se performance for grain yield per plant, genotype SAM-106, SAM-102, SAM -110, SAM-109 and SAM-105were found promising as they showed high value for grain yield and its components of wheat. Wide range of phenotypic (VP or O2 p) and genotypic variance (VG or O2 g) were observed in the experimental material for all the traits studied. High estimates of genotypic coefficients of variation (GCV) and phenotypic coefficients of variation (PCV) were obtained for plant height followed by biological yield per plant, harvest index, seed yield per plant, tillers per plant and number of grains per spike suggesting sufficient variability and thus scope for genetic improvement through selecting for these traits. Grain yield exhibited positive and significant correlation with days to maturity, plant height, number of grains per spike, and number of spikelet per spike. Number of productive tillers per plant, Weight of 1000 seeds, No of spikelet per spike, days to 50% heading and flag leaf length/cm had positive direct effect on total yield per plant.
