EFFECT OF BUDWOOD IRRADIATION ON SEED NUMBER OF 'CLEMENTINE', 'NOVA' AND 'ROBINSON' MANDARIN MUTANTS
In 2004, Clementine, Nova and Robinson budwood was Gamma irradiated at 30 and 50 gray doses. Irradiated buds were grafted on sour orange to produce M1V1 (first stage of mutation and vegetation) plants. Thus, M1V2 plants were produced from buds from M1V1 plants grafted on sour orange. In the same way, M1V3 plants have been obtained from M1V2 buds grafted on sour orange. In 2007, a total of 675 M1V3 plants were planted in the field with 5×2 m spacing. Ten non irradiated control plants were also planted in the same field. For two years, seed number of 135 Clementine, 110 Nova, 165 Robinson potential mutants and control plants were determined. Fruits of each plant were harvested at maturity (November) in 2010-2011 and average seed number of all plants was determined. As a result, budwood irradiation decreased seed number in resulting mutant plants, especially for Nova and Robinson mandarins.
