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.

Field studies were carried out in the localities of different altitudes and vegetation covers in the Hatay province in March-October 2018. Papilio demoleus was caught with insect net in the citrus orchards at Antakya and Reyhanlı. Cornifrons ulceratalis, Macaria alternata and Camptogramma bilineatum were caught mercury vapour light trap and white screen in different localities, at different elevations, in different climatic conditions, plant cover and sutface features in Erzin. Papilio demoleus was caught in the citrus gardens in the province of Hatay Reyhanlı district as a male and a female on 05.09.2018 and in Antakya district on 15.10.2018 as two male and three female individuals. This invasive species is widespread all over the world and has the potential to create substantial threat for citrus orchards in the Mediterranean region and in the eastern Mediterranean region of Turkey in next years. As a result, Papilio demoleus (Papilionidae), Cornifrons ulceratalis (Crambidae), Macaria alternata and Camptogramma bilineatum (Geometridae) are new records for the lepidoptera fauna of Hatay.

The agricultural production model which is done in order to provide food security, sustainability, and traceability in the agriculture, protect the natural sources and perform agricultural production, harmless to the environment, human and animal health, is called as Good Agricultural Practices. This study covers agricultural enterprises engaged in good agricultural practices and non-engaged in good agricultural practices in Adana province. The aim of the research is to compare the general characteristics of farms and to determine their views on good agricultural practices. The main material of the study constituted the primary data obtained through the survey of the 170 enterprises engaged in good agricultural and the non-used citrus (lemon and mandarin) farming in Adana province. According to the survey, it was determined that a higher level of education in enterprises engaged in ITU. The majority of good agricultural producers are residents in cities and towns and have social security. About 84.71% of good agricultural producers practise ITU in order to benefit support. It was determined that 25.88% of no good agriculture practices found ITU unnecessary. The 67.06% of producers stated that the market situation of the ITU products is similar to conventional products.
