Pengaruh Mutasi Fisik Iradiasi Sinar Gamma terhadap Keragaman Genetik dan Penampilan Coleus blumei

The need for fruit in Indonesia is increasing every year along with the increase in population. The increasing demand for longan fruit with good quality and small seeds (seedless), it is necessary to plant breeding. Longan plant improvement can be done by various methods, one of which is mutation method with gamma ray radiation. This study aims to determine the diversity of longan plant mutants and changes in the character of longan plants due to mutations of gamma ray radiation. In this study, three varieties were used, namely longan Itoh, Wusan, and Kateki with two doses of gamma irradiation, namely 50 and 60 gray (Gy). There are changes in plants, namely in the morphological character and the rate of photosynthesis. The percentage of vegetative propragation was 1%.

Indigofera zollingeriana plant has high production and quality as ruminant feed. Its development is constrained by the availability of land. The alternative is to expand the agricultural area towards marginal lands. This study aims to evaluate the genetic diversity of Indigofera plants through gamma ray irradiation. Indigofera seeds were irradiated at doses: 0, 100, 200, 300, 400, 500, 600, 700, 800, 900, and 1000 grays. Based on the LD50 test, plants with radiation doses of 0 Gy, 100 Gy, 200 Gy, and 300 Gy are the best. The study was continued with a field growth test, in a randomized block design, four radiation dose treatments with 20 replications (plants). The parameters observed were plant growth characteristics, dry matter production and chemical composition. The results showed that the 300 Gy dose was higher and significantly different from other treatments in the parameters of plant height (268 cm), canopy width (195.5 cm) and fiber content (14.81%). The 0 Gy treatment was superior on the number of leaves (2,972), number of flowers 311, and calcium content of 1.76%. It was concluded that the dose of 0 and 300 Gy had advantages on the growth and production of Indigofera plants.
