Growth Response of Two Soybean (Glycine Max (L.) Merr) Varieties Denna 1 And Rajabasa Subjected to Radiation Mutation Technique

Abstract

One of the national initiatives to lessen reliance on imports of soybeans and attain soybean self-sufficiency by 2022 is soybean production. Gamma rays are used to irradiate the Denna 1 and Rajabasa kinds of soybean seedlings. The treatments utilized were planted in metal trays and varied from 0 to 1000 Gy. The germination rate was 40% in Rajabasa at 900 and 1000 Gy, which was the lowest, and 88.35% at 0 Gy on Denna 1. Denna 1 had the highest plant height at 0 Gy (34.53 cm), while Denna 2 had the lowest at 800 Gy (1.30 cm). Denna 1 had the most leaves (6.40 cm) at 200 Gy, whereas Rajabasa had the fewest at 400 Gy (0.50). Rajabasa-2 had the highest flowering age at M3 generation (44,33 days) and Denna-1.3 had the lowest (300 Gy) (41,67 days). Rajabasa mutant line had the maximum weight of full pods at 200 Gy (55,33 g), whereas Rajabasa-1 showed the lowest weight at 300 Gy (33 g). The outcome of this dosage orientation experiment may assist in determining the ideal dose for post-irradiated plants.
