“…Goldenberg et al (2014) observed that average fruit weight of one of the eight lowseeded irradiated mandarin varieties was significantly higher than those of varieties from non-irradiated trees. In addition, Rattanpal et al (2019) marked that fruit weight should be used as a selection trait in the mutation breeding studies in case the variability coefficient is high. In citrus, fruit shape is also an important quality trait that attracts consumers' attention as well as fruit size.…”

The existence of a large amount of seeds in citrus fruits results as a major impediment to customer acceptability, even if the fruits have high organoleptic properties. Irradiation, which mainly reduces seed number of varieties, is a faster way than hybridization. The use of irradiation in citrus breeding programs is now quite widespread with most programs in the major citrus producing countries actively developing new selections. The present study reports the primarily results of gamma irradiation on seed number and fruit quality of Ortanique tangor mutant population. The shoots of scion were irradiated with gamma rays from 60Co at the dose of 50 Gy (gray) in April of 2014. All the treated buds were then immediately budded onto rootstocks and the survival rate was recorded as 60.34%. In order to stabilize the mutation, mV3 plants were developed by re-budding and plants at mV3 generation were transplanted in the orchard in 2017. Within the following year, 68 mV3 plants out of 852 grown in the field bore sufficient amount of fruit and were screened in terms of 19 fruit quality characters such as seed number per fruit, fruit diameter and ripening index. Fruit diameters of mV3 population varied from 56.72 mm to 84.79 mm, and fruit weight ranged between 90.00 g and 287.60 g. The number of seeds per fruit ranged between 0.6 and 13.1 whereas seed number of non-irradiated Ortanique tangor was recorded as 10.7 in the same fruit crop year. In general, fruit characteristics such as fruit weight, fruit height and fruit diameter which describe fruit size of a big part of the population, were similar to Ortanique tangor. According to primarily results, 18 plants have been described as low seeded (≤4). In addition, a cluster analysis was performed by using Euclidean similarity coefficient and similarity index ranged between 29.29% and 93.10% regarding variables related to fruit. The stability of mutations detected is being evaluated and new commercial field trials will be established with the selected materials.

“…Improvement of plant varieties through mutations with gamma rays is considerably more effective in increasing the diversity of Citrus (Arisah & Mariana, 2017). Gamma irradiation could produce high mutations to create new variants which are different from the wild orange type (Rattanpal, Singh, & Gupta, 2019).…”

Effect of Gamma Rays Irradiation and In Vitro Selection on Citrus nobilis (L.) ‘Siam Banyuwangi’ to Huanglongbing (HLB) Disease

Siam orange (Citrus nobilis L.) provides great economic value and social importance, despite its susceptibility to Huanglongbing (HLB) disease caused by Ca. Liberabacter sp., classified as specific bacterium phloem vessels marked by the formation of callouses covering plasmodesmata. This research aims to improve the tolerance of Siam orange from Banyuwangi (SB) to HLB disease. The experiment was undertaken by performing a randomized design (CRD) with one factor (irradiation dose). This study consists of two interrelated experiments, which include: induction of embryo mutations with gamma rays irradiation, and in vitro selection of putative mutant. The embryo of SB was irradiated by gamma rays with doses of 0, 45, 50, and 55 Gray. Each treatment was repeatedly undertaken for five times with 20 embryos. After 24 weeks, in vitro selection of putative mutant shoots was screened by HLB pathogen suspension. The observation indicated that treatment of gamma rays in various doses influenced embryo germination. In general, gamma ray irradiation gave significant effects on embryo germination and plant morphological characters. In vitro selection results for putative mutant on doses of 45, 50, and 55 indicated tolerance to HLB pathogen after selection.
