Abstract
Peanut or groundnut (Arachis hypogaea) is a species in legume or bean family. The peanut was probably first domesticated and cultivated in the valleys of Paraguay. India is the second largest producer of groundnut in the world. It is the major oil seed crop in India and it plays a major role in bridging the vegetable oil deficit in the country. The experimental material consisted of Chinthamani groundnut variety popularly cultivated in and around the areas of Tenkasi district. It was conducted in two farmers’ fields at Tenkasi district during rabi and kharif of 2021. Two hundred plants in each field were analysed for yield contributing components on pod yield per plant to identify the easily observable trait useful in indirect selection for high yield. During rabi season, the traits height of main axis, number of flowers within 45DAS, number of matured pods, and kernel yield were positively correlated to pod yield while number of branches, number of flowers within 45DAS, matured pods, kernel yield, hundred pods weight and hundred kernels weight are positively correlated to pod yield during Kharif season. The path analysis disclosed that the trait number of matured pods per plant and kernel yield had high direct effect towards pod yield per plant in rabi season and number of matured pods per plant was recorded during kharif season. These results imply that selection for these traits would bring up the improvement in the associated characters and in turn improvement of yield simultaneously.
