• Two sublines, B-202 and B-207, which were derived from crosses between Or-R (M) females and Cy/Pm (P) males were found to cause a new type of gonadal dysgenic sterility, designated as the GD-3. GD-3 sterility showed a typical reciprocal cross effect under the P-M system. It was caused at the frequency close to 100% in dysgenic offsprings reared above 25°C, of which gonads were morphologically clearly different from those of usual GD sterility, whereas there was no indication of GD-3 sterility at temperatures below 24°C. Temperature sensitive period of GD-3 sterility was estimated to the prepupal stage by shift-down experiment. In the B-202 subline, the 2nd chromosomes marked with Pm alone carried GD-3 elements. Those of the B-207 subline, however, were estimated to locate both on the 2nd and 3rd chromosomes, acting synergistically with each other.
