Abstract: | Haploids were extracted from 66 differentSolanum tuberosum Group Andigena introductions usingS. tuberosum Group Phureja clone 1.22 as pollinator. The overall frequency of haploids was 13 per 100 fruit, with a high of 106. The overall average number of seeds per fruit was 1.4. Some Group Andigena clones produced primarily haploid, others primarily triploid, and still others primarily tetraploid progeny. The “triploid block” is still evident in these materials even though some clones produce primarily triploid progeny. It is suggested that the ploidy level of progeny produced in 4x - 2x crosses may be under relatively simple genetic control. |
