Studies on Flowering Pattern in Relation to Seed Filling and Seed Multiplication Rate in Groundnut (Arachis hypogaea L.)

The experiment was conducted in order to find out the effects of differential number of flowers plant-1 on pod and seed characteristics in the Department of Seed Science and Technology, Tamil Nadu Agricultural University, Coimbatore. In this experiment, the different number of flowers plant-1 was retained by manual pinching of late formed flowers. The number of flowers retained plant-1 varied from 11.08 (25 to 35 DAS), 36.63 (25 to 45 DAS), 89.33 (25 to 55 DAS), 125.04 (25 to 65 DAS), 169.32 (25 to 75 DAS), to 244.89 flowers (control plants). The yield attributing pod and seed characters viz., number of double seeded mature pods plant-1, weight of double seeded mature pods plant-1, number of mature seeds plant-1, weight of mature seeds plant-1 were highly influenced by the flowers retained between 25 to 55 days after sowing over control.
