Summary
-
1.
Genetic variability among 29 haploids (2n=24) of the common potato (2n=48) is described.
-
2.
Plant parts of the haploids are reduced in size, with few exceptions, as compared with those of the parent.
-
3.
The tuber yields of the haploid plants are in general, considerably less than those of their parents. One notable exception, however, is the haploid US-W20. which in an initial limited trial outyielded its parent Katahdin in a 124-day growing season.
-
4.
Twenty-two of the 23 haploids that flowered are functional as female parents. Two haploids. US-W1 from Katahdin and US-W4 from Minn. 20-20-34, are functional both as male and female parents in interhaploid matings as well as in matings withSolanum phureja (2n=24).
-
5.
Certain genetic consequences of haploidy are discussed.
