Judul: Studi irradiasi sinar gamma pada tanaman iles-iles (Amorphophallus muelleri Blume)
Abstrak: Konjac (Amorphophallus muelleri Blume) is a triploid tuberous crop plant which produces apomictic seeds. It makes the genetic diversity of the plant is considered low. The objective of this research was to increase the diversity of konjac and to get a potential mutan in order to develop breeding materials. Gamma irradion was used in this experiment. The gamma irradiation was applicated in konjac’s seeds, using eleven treatments including control, from 0 Gy to 100 Gy with 10 Gy in every interval of the treatment. Result showed that control (0 Gy) and 10 Gy treatments that had succesfully produced potential mutans . Treatments level higher than 20 Gy to100 Gy caused mortal plant or kept seeds dormant until the end of the experiment. The 10 Gy treatment significantly delay seed sprouting more than five weeks after planting. All of the vegetative parameters of 10 Gy’s treated plants significantly exhibited lower productivity than those of control plants. Some mutans were observed on the leaf morphology. This experiment revealed that A. muelleri seed was sensitive to gamma irradiation.

Abstrak: Cassava (Manihot esculenta Crantz.) is one of important food source, therefore it is very important to increase cassava yield and starch content, and decrease HCN content in the tuber through efficient breeding program. High genetic diversity is one requirement in successful breeding program. The objective of this experiment was to increase genetic variability of ‘Gajah’ genotype cassava from East Kalimantan through gamma irradiation. Stem cuttings of cassava were irradiated in PATIR-BATAN and planted in Cikabayan Experimental Field, IPB from December 2012 to June 2013. This research was arranged in randomized completely block design with one factor that was gamma ray irradiation rate. The gamma irradiation rate consisted of five levels i.e. 0, l5, 30, 45, and 60 gray (Gy). The research results showed that the LD20 was 16.04 Gy and the LD50 was 21.49 Gy. Gamma irradiation did not significantly affect the vegetative growth of cassava, but it caused changes in several morphological characters, i.e. pubescence on apical leaves, color of apical leaves, leaves retention, shape of central leaflet, petiole color, number of leaves lobes, and orientation of petiole. One of mutant candidate from 15 Gy-irradiated plants produced 17 tuber per plant, thus it is potentially developed further.
