May, 1923] VALLEAU-INHERITANCE IN THE STRAWBERRY 
26l 
The seedlings studied fall into five groups based on parentage. These 
are as follows: Hermaphrodite X self, hermaphrodite X hermaphrodite, 
male X male, female X hermaphrodite, and female X male. The various 
combinations will be considered separately. 
The term female will be used in referring to pistillate plants bearing 
abortive anthers; male in referring to the somatic hermaphrodites which 
generally bear sterile pistils, and the term hermaphrodite in referring to 
those perfect-flowered forms which are fertile with regard to both pistils 
and pollen. 
Hermaphrodite X Self 
Table 1 gives the results of self-pollinating hermaphroditic varieties of 
strawberry. A total of 352 hermaphrodites, or somatic hermaphrodites, 
and no pistillates were produced when 11 distinct clones were selfed.

In view of the number of different parent plants used, the results go to 
prove that hermaphrodites do not carry the factor for femaleness and are 
therefore homozygous for the hermaphrodite determiners. These results 
are in keeping with the condition found in the hermaphroditic wild species 
F. americana, which must be considered to be homozygous for the hermaph¬ 
rodite determiners. They are also in keeping with results of strawberry 
breeders who never expect pistillate varieties to result when only hermaph¬ 
rodites are used as parents. 
Although all these seedlings were hermaphrodites as far as somatic 
condition is concerned, there were distinct differences in the fertility of 
some of them. Lot 32/16, an Fi of 778 X self, produced 18 fertile plants 
and one which was sterile. Sterility in this one may have been the result 
of weakness, due to self-pollination or to some other cause.
