Abstract: The induction of wheat (Triticum aestivum L.) pollen plant using simplified culture medium of Sechium edue (Jacg.) Sw. (table 1.) was studied For inducing callus, the simplified culture medium of potatot (abbr."potato") was used as the control midium. For inducing differentiating plantlets, we used the culture medium, MS + IAA 0.5mg/l+kinetin 2mg/1 (abbr. "MS" ) as the cohtrol medium. In inducing callus,the inducing frequencies of the two media, "potato"and "chayote + kinetin",were found to be different with different material (table 2, table 3.) .In many material, inducing frequency of "potato" is higher.However, when induced callus from the two culture media were transferred to differentiation culture medium "MS", more albino plants were differentiated; in the former and more green plants in the latter. It is noteworthy that the frequency of induced callus in "chayote" culture medium is higher than in "chayote + kinetin" (table 3).
