TABLE 7/C.--Relative heights, weights, and fertility of plants from
parents crossed by a fresh stock, and from parents either
self-fertilised or intercrossed with plants of the same stock.
Column 1: Names of the plants and nature of the experiments.
Column 2: Number of plants from a cross with a fresh stock.
Column 3: Average height in inches and weight.
Column 4: Number of the plants from self-fertilised or intercrossed
parents of the same stock.
Column 5: Average height in inches and weight.
Column 4: x, where the ratio of the Height, Weight and Fertility of the
plants from the Cross with a fresh stock is expressed as 100 to x.
Ipomoea purpurea--offspring of plants intercrossed for nine generations
and then crossed by a fresh stock, compared with plants of the tenth
intercrossed generation:
19 : 84.03 : 19 : 65.78 : 78.
