Pod and seed development and phenotype of the M1 plants after pollination and fertilization with irradiated pollen in cacao (Theobroma cacao L.)


In order to try to induce parthenogenesis, Theobroma cacao L. pollen of the clone K5 was gamma-irradiated at 0, 50, 70 and 90 Gy and used to pollinate flowers of the clones IMC67 and T85/799. Fruit survival rate 30 days after pollination decreased as pollen irradiation dose increased. LD50 was about 70 Gy for IMC67 and 75 Gy for T85/799. Pods obtained from… (More)
