Improvement of morphology, biochemical characters, and molecular changes of local upland rice cv. Sidikalang M3 generation through induction of gamma-ray irradiation

Abstract. Naibaho D, Purba E, Hanafiah DS, Hasibuan S. 2023. Improvement of morphology, biochemical characters, and molecular changes local upland rice cv. Sidikalang M3 generation through induction gamma-ray irradiation. Biodiversitas 24: 200-207. Upland cultivar is one the red cultivars North Sumatra, which has potential to be developed. However, this limited planting area due factors such as its higher plant height long duration compared other cultivars. Plant characteristics can improved induced mutation using This study aimed determine gamma rays' effect on in morphological, biochemical, characters obtain a superior mutant generation. Observations morphological were carried out quantitatively qualitatively, analysis (amino acid content) was done High Performant Liquid Chromatography analyzer, performed Random Amplified Polymorphism DNA markers. The results showed that 600 Gy irradiation quantitative (shorter height, number tillers panicles, faster panicle release age) qualitative (flag leaf angle dwarf mutants became upright) no 400 also increased almost all amino content presence polymorphic bands evidenced characters.
