Molecular tagging of seed size using MITE markers in an induced large seed mutant with higher cotyledon cell size in groundnut.

Unlabelled: A large seed mutant, TG 89 having a 76.7% increment in hundred kernel weight in comparison to its parent TG 26, was isolated from an electron beam-induced mutagenized population. Studies based on environmental scanning electron microscopy of both parent and mutant revealed that the mutant seed cotyledon had significantly bigger cell size than parent.

Electron beam irradiation revealed genetic differences in radio-sensitivity and generated mutants in groundnut (Arachis hypogaea L.).

Electron beam accelerators are being used for many industrial applications including food and agriculture. A 10MeV linear accelerator facility was standardized for low dose application 0.1-1 kGy) in pulse mode using unscanned scattered beam for irradiation of groundnut seeds for mutation breeding.
