The tetraploid plants were induced with 1/300, 1/450 and 1/600 colchicine solutions, and the best results were obtained from the treatment of 1/450 colchicine solution. 7 plants of tetraploidity obtained I this study bore one fruit each, and low fruit setting and seed fertility were found in the progeny, only 5 plants of line 16-A1-1 and 4 plants of line 46-C2-11 produced 8 fruits with 68 seeds and 2 fruits with 11 seeds, respectively.
