ABSTRACT

The field experiment was carried out at Dry land farm, Regional Agricultural Research Station (RARS), Tirupati during kharif, 2024 to study the correlation analysis of yield, 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. Eleven traits were evaluated which include kernel yield plant-1, pod yield plant-1, 100 pod weight, 100 kernel weight, kernel mass, shelling percentage, sound mature kernel percentage, kernel length, kernel breadth, iron and zinc content. Character association studies revealed that pod yield plant-1 showed positive and significant association with kernel yield plant-1, 100 pod weight, 100 kernel weight, kernel length, and sound mature kernel percent. This indicates that these traits play a crucial role in the selection of genotypes for improving pod yield.

KEYWORDS: Groundnut, character association, pod yield, yield traits.
