“…The decline in viability and germination ratios under low dosage may result from radiobiological injury. Similarly, Masuda et al (1998) also reported that pollen fertility in L. esculentum plants was lower in 200 Gy than 100 Gy. After gamma irradiation with high dose (400 Gy) the pollen tubes may destroy by a degradation process which leads to lysis of the tubes.…”

Pollen viability and germination in vitro and in vivo were influenced by gamma irradiation for dosages of 0 (control), 100, 200, 300, and 400 Gy when this was applied to early and late trusses (1st-5th and 6th-10th) 4 times in a year (early spring, late spring, early autumn, and late autumn) in three cultivars of tomato (Lycopersicon esculentum) ('Gulle', 'Likya', and 'XPH5811'). The trial was carried out in 2003 and was repeated in 2004. Timing 1 was applied to flowers in trusses 1-5 (early spring, early autumn), and timing 2 to flowers in trusses 6-10 (late spring, late autumn). exposure of pollen to high gamma doses, 300 and 400 Gy, resulted in the lowest rates of pollen survival and germination. Time of year and cultivar also had affects on pollen viability and germination rates. Viability and germination following exposure to gamma irradiation were not affected by the position of the truss on the plants. In situ pollen tube growth was recorded for all radiation dosages, pollen tubes of irradiated pollen were shown to grow successfully through the style and to enter the ovules.

“…Thus, this variety requires mutation to increase their production and characteristics, hence improving the overall plant performance. Mutation was introduced to induce new important traits concerning plant size, blooming period and fruit ripening, fruit colour, self-compatibility, self-thinning and resistance to pathogens [4]. Mutagenesis was also used for direct improvement of certain qualitative and quantitative characters of the plant.…”

The present work was carried out to investigate the effects of gamma radiation on regeneration of Capsicum annuum L. var Kulai via in vitro. Seeds of C. annuum were irradiated with various doses of gamma ray (0, 20, 40, 60, 80, 100, 200, 300, 400, 500, and 600 Gy) emitted from the Caesium-137 source at the rate of 4.31 Gy per minute. Irradiated seeds grown on MS medium without hormone for hypocotyl and cotyledon preparation as explant for in vitro regeneration. Seed germination rate revealed significant variation between treatments, and seeds started to germinate between 6 to 17 days. Irradiated seeds between 0-60 Gy were observed to germinate in less than 10 days. All explants including hypocotyl and cotyledon were cultured on MS medium with different concentrations of BAP in combination with AgNO3 to observe the response of these explants to different hormone concentrations. From the observation, calluses were induced in 90% of hypocotyl and cotyledon explants in all treatments. The characteristics of calluses were varied with greenish friable, greenish compact, yellowish watery, yellowish friable and yellowish compact. In other treatments, calluses were found in purple, bright yellow and yellowish orange. On the other hand, shoot regeneration was observed in treatment between 40-100 Gy. In conclusion, gamma radiation gave impact on seed germination, seedling growth performance, in vitro callus formation and shoot regeneration of Capsicum annuum var. Kulai
