muskmelon pollen. Even if crossing occurred, there is no conclusive
evidence that xenia would result.
CUCUMBER
Wellington, (1913) studied the inheritance of the following characters:
color, size, number of spines, smooth or rough skin, and
obtained ratios indicating monohybrid segregation. Smooth skin
and small spines, few in number, appear to be linked. Heterosis
shown by increased number or size of fruit, has been observed
in the Fi of certain cucumber crosses (Hayes and Jones, 1916).
The Fi of a cross (Reeves, 1918) between American type (20 per
cent parthenocarpic) and English type (normally parthenocarpic)
showed 20 per cent parthenocarpy.
MUSKMELON
Lumsden (1914), of the New Hampshire Agricultural Experiment
Station, has made rather extensive studies of inheritance
in the muskmelon. The following tabular statement gives a
summary of his work:
