Tias Ayu Pratiwi, Rina Puji Lestari, Parjanto and Ahmad Yunus

Abstract:
Background and Objective: Mentik Wangi is local rice variety from Magelang, Central Java. This rice has superior properties, which is tender texture, has fragrant, but also has a long harvesting age and tall stems so that it easily collapses during heavy wind. The purpose of this study was to determine the performance of M2 mutants resulting from 150, 200 and 250 Gy gamma irradiation and to find out the plants to obtain short-stemmed, short-lived mutant plants with high productivity. Materials and Methods: The tools used in this study include tractors, hoes, rakes, sickles, stakes, code boards, gauges, rulers, raffia, scissors, analytical scales, newspapers, stationery. The materials used are M2 generation Mentik Wangi rice seeds which are the result of 250 Gy gamma-ray irradiation, control Mentik Wangi rice seeds (without radiation), urea fertilizer, Ponska, SP36, KCl, ZA and pesticides. Plant treatment includes weed control, irrigation, fertilization, pest and disease control and put nets to avoid bird attacks. The study was conducted using a simple design experiment. Results: The results showed the difference between Mentik Wangi rice M2 generation gamma-ray irradiation with control plants. The results of the selection of short-trunked mutant plants, short-lived and have high productivity. Conclusion: M2 selection obtain 11 plants mutant from irradiation with 150 Gy, 22 plants mutant from irradiation with 200 Gy and 24 plant mutant from irradiation with 250 Gy that have short stems and high productivity.
