“…Irradiation processing by γ-irradiation up to a dose of 1 kGy has been recommended for quarantine treatment of legumes including soybeans [1]. Gamma irradiation can be also used to develop economically improved sorts of different plants (varietes with high productivity potential, resistant to dieases, salt and environmental factors) [2][3][4][5]. Research on the effects of γ-irradiation on food has been done with a little information avaliable on antioxidant system in plants.…”

There are some reports that low doses of γ-irradiation could induce antioxidant activities in plant material, including soybean. Irradiation, required for the inactivation of some pathogens and induction of mutations, may have adverse effects on sensorial, nutritional and antioxidant qualities. The effects of different γ-irradiation doses (100-200 Gy) on antioxidant properties of soybean seeds was investigated. In this study, we report the results obtained by analysis of antioxidant enzyme activities, reduced glutathione, malonyldialdehyde (MDA) and hydroxyl (HO˙) radical quantities, soluble protein content, and total antioxidant activity in irradiated soybean seeds. Antioxidant enzyme activities were affected due to high irradiation intensity. Significant changes of total antioxidant activity and MDA and HO˙quantities were observed only under the highest irradiation dose, with a 15.7% reduction in total antioxidant activity, MDA quantity increase of 21.6%, and HO˙ radical quantity increase of 79.3% compared to the non-irradiated control. The total soluble protein content increased slightly.

“…The highest crude oil yield is Ege-2001 in 33,49% at 400 Gy dose (Figure 3). Radiation practise are very important in mutation breeding in order to develop necessary features of plants and increasing the genetic variability (Jain et al, 1998). The lowest crude oil yield is Tunca in 10,66% at 100 Gy dose compare to control (Figure 4).…”

This study compares the effects of different doses gamma radiation on crude oil yield and moisture of different six variety sunflower (Helianthus annuus L.) seeds. As materials, sunflower variety Ege-2001, Turay, AS-508, Tunca, TR-3080 and Tarsan-1018 seeds were used and irradiated with doses of 100, 200, 300, 400 and 500 Gy gamma radiation. Control groups were not subjected to gamma radiation. Irradiation was performed in a cesium (Ce 137 ) Gammacell 3000 Elan source, dose rate about 9.75 Gy/min (2900 Ci) in the Pamukkale University Faculty of Medicine in the department of the radiological. Moisture amount of seeds were also measured by AOCS standarts. Extraction of the seeds was done with soxhlet apparatus using petroleum ether by hot continuous extraction for 6 hours. It was found that the highest moisture rate in 100 Gy for all seeds variety. The moisture rate ranged between 3.00 and 9.68% in TR-3080 and Ege-2001, respectively. According to our results, the moisture content of the seed negatively affected by gamma radiation. The significant reduction in seed moisture content (9.68%) began at 100 Gy of gamma rays and continued to decline to up to 4.04% at 500 Gy. The crude oil yield showed not a important increase in 100 and 200 Gy doses. The result showed that the highest crude oil yield was also obtained from 400 Gy and 33.49% in Ege-2001 seeds.

“…Fortunately, chimeras can be converted into solid mutants by repeated multiplication (Yang and Schmidt, 1994). Therefore, it is highly desirable to dissociate chimeras by subsequent subcultures up to M1V3-M1V4 generations (Jain et al, 1998;Mandal et al, 2000). This should be done to maintain the stability of mutant traits and to ensure that the selected mutant lines are solid mutants or stable periclinal chimeras.…”

Mutation breeding techniques in combination with tissue culture and molecular marker methods provide a powerful tool for improvement of vegetatively propagated plants. The aim of this study was to develop a protocol for shoot regeneration and mutation induction of Etlingera elatior. The results of irradiation on in vitro buds of E. elatior showed LD 50 to be 10 Gy, with the survival of explants being sharply reduced at this dosage. All 8 selected gamma irradiated regenerants were differentiated from the untreated control based on the banding patterns obtained using 9 primers, which generated 59 reproducible bands, whereby 35 (55.31%) were found to be polymorphic. Jaccard's coefficient of similarity values ranging from 0.537 to 0.860 were indicative of the level of genetic variation among the mutants studied. For comparison between the potential lines (PL) and the control, a maximum similarity value (0.814) was observed in PL1 mutant, while the minimum value (0.537) was observed in PL7. In summary, a combination of irradiation, regeneration, multiplication, and random amplification of polymorphic DNA (RAPD) analysis for early screening of mutants can speed up the breeding program of E. elatior.
