Abstract
This research aims to assess the radiosensitivity of Bengal grass cv Mombasa and the influence of the M1V1 generation on the shade-tolerant assembly of Bengal grass cv Mombasa. The study was conducted at the experimental garden of the Indonesian Research Institute for Animal Production (IRIAP), Ciawi, Bogor in 2022, using a paired T-test design for Bengal grass cv Mombasa resulting from gamma-ray irradiation at 100, 200, 300, 400, 500, 600, 700, and 800 Gy with shade treatment (50%) and without shade (open cultivation). Observed Bengal cv Mombasa parameters were agronomic performance and grass productivity. Radiation treatment had a significant influence (P 0.05) on plant height, leaf length, lower leaf length, lower leaf width, number of shoots, and stem weight, but not on stem height, leaf width, internode length, internode diameter, panicle length, number of flowers, or total weight. Four hundred Gy of gamma irradiation resulted in the greatest plant height, while 100 Gy of gamma irradiation resulted in the greatest plant mass.
