Kajian: Pengembangan Varietas Unggul Baru Padi (Oryza sativa L.) Lokal melalui Iridasi Gamma

Abstract

The widespread use of mutagenesis for plant genetic improvement can be explained by a number of factors, including the fact that new varieties can be developed in a shorter time than conventional breeding methods and that transgenesis is more difficult to re-engineer. Gamma rays are physical mutagens that are often used in plant mutagenesis techniques and are safe for human health because there is no environmental risk in the induced generations. The method used in this paper is by grouping articles according to their relevance to the subject and year of research, and finally managing the explanatory structure. Journal articles for the period 2012 to 2022 were searched using keywords: breeding, mutation, mutagen, rice, and gamma iridation. The selection of selected articles comes from the PubMed, Elsevier, and Springer web sites. This paper integrates the available data on the effects of mutation breeding of plant varieties in different countries and addresses the potential of gamma irrigation as a flexible and practical approach that can be applied to rice crops and an appropriate selection method.

“…Pernyataan Alfarisi et al (2018) bahwa pengaruh pemberian dosis sinar gamma tepat dalam bidang pertanian akan diperoleh tanaman yang mempunyai sifat-sifat seperti hasil tinggi, umur pendek dan tahan terhadap penyakit. Mutasi yang diharapkan dapat menyebabkan tekanan selektif pada sifat yang dipilih, memungkinkan pemilihan sifat dengan kualitas yang lebih baik, sementara sifat yang diinginkan dari galur asli dipertahankan (Sari et al 2023).…”
