Experimental plot was conducted to the study of correlation coefficient of 21 parents line × tester mating design in bread wheat (Triticum aestivum L.) under the area of Department Genetics and Plant Breeding, farm during the rabi season 2023-24 and 2024-25 was evaluated for correlation coefficient for 16 traits i.e., Day to 50% heading, Day to maturity, plant height, number of total tillers per plant, spike length, number of spikelets per spike, number of grains per spike, number of grains per plant, flag leaf area, harvest index, 1000 grain weight (g), biological yield per plant (g), gluten content, protein content, chlorophyll content, canopy temperature depression and grain yield per plant (g) in 181 treatments including 21 parents, their 80 F₁ and 80 F₂ generations. The findings revealed a strong positive genotypic correlation of grain yield per plant with biological yield, followed by spike length, number of total tillers, 1000-seed weight, chlorophyll content and gluten content in both the generations. While phenotypic correlations were generally lower than genotypic ones, they reinforced the importance of these traits in yield improvement. The results suggest that breeding programs focusing on these key traits can effectively enhance wheat yield potential.
