“…In addition, the application of 200 Gy gamma ray radiation created genetic changes in black rice in term of plant height (Warman, Suliansyah, Swasti, Syarif, & Alfi, 2015). This result was in line with other experiment which revealed that 200 Gy gamma ray decreased the plant height of Cempo Ireng black rice (Masruroh, Samanhudi, Sulanjari, & Yunus, 2016). Gamma ray irradiation reduced the seedling height of black rice, decreased the plant height and stimulated flowering day (Yuwono & Sutoyo, 2017).…”

“…It means that the effect of radiation varied. Masruroh, Samanhudi, Sulanjari, & Yunus (2016) stated that the highest anthocyanin content from black rice was generated from 500 Gy radiation compared to the lower dosages from 100, 200, 300 and 400 Gy. Moreover, 600 Gy produced the highest anthocyanin in rosella (Hisbiscus sabdariffa) (El Sherif, Khattab, Ghoname, Salem, & Radwan, 2011).…”

Black Rice is rice producing anthocyanin in high intensity and popularly consumed as functional food. Long harvesting age and low productivity are the inhibiting factors in black rice breeding. High plant crown potentially results in plant fall-down. Mutation induction is expected to be able to improve the character of black rice. Therefore, the objectives of this research were to get more early-ripening black rice mutant, with shorter plant crown and increase productivity by inducing mutation in three varieties of local black rice using gamma-ray radiation. This experiment employed three local varieties as the first factor comprised Cempo Ireng, Cempo Melik and Melik. The second factor was the gamma-ray radiation dose, consisting of 4 levels: without radiation, radiations at 100 Gy, 200 Gy and 300 Gy doses. The results indicated that Melik variety is very potential. Melik variety has shorter plant crown with a responsive character in number of tiller for higher productivity. Moreover, radiation significantly reduces the duration of flowering and harvesting. However, to achieve a more stable character and lower flowering and harvesting period, the radiation needs to be continued in the next generation. The doses of radiation produces a response that varies in both morphological and biochemical properties.

“…Radiasi sinar gama mampu memutus struktur DNA yang kemudian menyebabkan urutan sekuennya dapat berubah hal ini lah yang menyebabkan ekspresi/fenotipik yang dihasilkan bisa berbeda dengan Wild Type (Hanafy dan Akladious, 2018). Adapun mutasi induksi pada tanaman padi untuk memperoleh sifat unggul telah banyak dilakukan, seperti pada padi Ciherang, padi Cempo, padi Hitam lokal dan padi Mentik Susu yang dimutasi menggunakan sinar gama dengan dosis radiasi antara 200 gy hingga 300 gy memiliki karakteristik unggul produktivitas yang lebih tinggi, kadar protein yang lebih baik, tanaman yang lebih pendek, kadar amilosa rendah dan lama panen yang lebih cepat (Masruroh et al, 2016;Aprida dan Yuwono, 2017;Rachmawati et al, 2019). Belum ada penelitian untuk memperbaiki sifat padi Barak Cenana menggunakan sinar gama, sehingga pada penelitian ini dilakukan radiasi pada biji padi dengan dosis 100, 200, 400, dan 800 gy.…”

Red rice cv. Barak Cenana is a local Indonesian rice which is widely planted in Tabanan Regency, Bali. Barak Cenana red rice has potential as a functional food because it contains a lot of nutrients. However, this rice has an unfavorable character, such as long harvest time so that it can only be harvested once a year, and tall stature that causes plants to lodge easily, reducing its productivity. This study aims to determine the effect of gamma rays on growth and development as well as changes in character to obtain mutants plants that have better character. In this research, Barak Cenana seeds were irradiated using gamma rays with irradiation doses of 100 gy, 200 gy, 400 gy, and 800 gy. Furthermore, radiated seeds were planted in the greenhouse and characterized during the vegetative and generative phases including shoot length, harvest time, chlorophyll content, the number of productive tillers, the number of grain contents, the weight of 1,000 seeds, and the polymorphism profile using Random Amplified Polymorphic DNA Analysis (RAPD). The results of this study indicate that all radiation doses produce plants with random characters. Mutations using gamma rays at doses of 100 gy and 400 gy produced plants with better phenotypic characters than wild-type that is shorter plants, shorter harvest times, and more grain content. In addition, the results of the RAPD analysis confirm that there are genetic changes in irradiated rice. This mutants has the potential to reproduce germplasm and to obtain the next generation of mutants that have higher productivity and shorter plant heights.

“…This is also supported by Sales et al (2013) CEMSA ¾ cultivar banana have a shorter flowering age than controls. Masruroh et al (2018) also declared that the doses of gamma irradiation had very significant effect on flowering date. This indicates that mutation has occurred due to radiation exposure of gamma rays, which causes changes in chromosome structure, thus affecting the emerged phenotypes like flowering date.…”

<a name="_Hlk39513249"></a>Raja Bulu is one of the banana varieties favored by the community because of its thick fruit flesh and sweet taste. However, its parthenocarpic characteristic and vegetative propagation make this banana variety has limited genetic variation. Attempt to improve the genetic variation was conducted through induced mutation breeding using gamma-ray mutagens. This research aimed to select M1V1 generation of Raja Bulu banana (Musa paradisiaca Linn.) obtained by gamma rays’ irradiation for their growth traits which are expected to produce banana varieties that have an early maturity and high yield. This study used a randomized complete block design without replication by observing the generative growth of each individual of Raja Bulu banana irradiated by gamma rays and without radiation as a control. The results showed that gamma-ray irradiation treatment caused Raja Bulu banana to be harvested earlier and produced higher fruit weight than controls. The gamma-ray irradiation had a random influence on Raja Bulu bananas. The 10 Gy gamma-ray irradiation dosage influenced the morphological diversity in the generative phase of Raja Bulu banana. The treatment of gamma irradiation resulted in 5 individual plants that flowered and matured earlier as compared to controls.
