Correlation and Path Coefficient Analysis for Grain Yield, Head Rice Recovery and Quality Traits in Rice Hybrids (Oryza sativa L.)

The study's main objectives were to analyze rice path coefficients and look at the associations between different features. 24 hybrids were created by crossing four CMS lines with six elite restorers utilizing a Line × Tester design. During the Rabi 2023–2024, these hybrids, the parental lines, and two checks were assessed using a randomized block design with two replications. Grain yield was found to be negative significantly correlated with the number of productive tillers per plant and the hulling percentage (%) and positive significantly correlated with plant height (cm), panicle length (mm), number of grains per panicle, 1000 grain weight (g), and kernel breadth (mm). Height of the plant (mm), length of the panicles (mm), number of grains in each panicle, weight of 1000 grains (g), length of the kernels (mm), percentage of milling (%), and head rice recovery had exhibited direct positive effect on grain yield per plant. Therefore selection based on these traits could facilitate simultaneous improvements in yield and related attributes.
