The field experiment was carried out at Dry land farm, Regional Agricultural Research Station (RARS), Tirupati during kharif, 2024 to study the correlation analysis ofyield, yield attributing and kernel micronutrient traits in groundnut. The plant material includes 20 diverse groundnut genotypes along with Rohini, as a check for kernel micronutrient content were considered for evaluating eleven traits which include kernel yield plant-1, pod yield plant-1, 100 pod weight, 100 kernel weight, kernel mass, shelling percentage, soundmature kernel percentage, kernel length, kernel breadth, iron and zinc content.Character association studies revealed that pod yield plant-1 showed positive and significantassociation with kernel yield plant-1, 100 pod weight, 100 kernel weight, and kernel length, sound mature percent.This indicates that these traits play a crucial role in the selection of genotypes for improving pod yield.

You can write a PREreview of Character Association Analysis of Yield, Yield Attributing and Kernel Micronutrient (Iron and Zinc) Traits in Groundnut (<em>Arachis hypogaea</em> L.). A PREreview is a review of a preprint and can vary from a few sentences to a lengthy report, similar to a journal-organized peer-review report.
