Crowded plants.
Total : 605.38 : 329.50 : 198.50.
In this table the average height of the twenty-eight Chelsea-crossed
plants is 21.62 inches; that of the twenty-seven intercrossed plants
12.2; and that of the nineteen self-fertilised 10.44. But with respect
to the latter it will be the fairest plan to strike out two dwarfed ones
(only 4 inches in height), so as not to exaggerate the inferiority of
the self-fertilised plants; and this will raise the average height of
the seventeen remaining self-fertilised plants to 11.2 inches. Therefore
the Chelsea-crossed are to the intercrossed in height as 100 to 56; the
Chelsea-crossed to the self-fertilised as 100 to 52; and the
intercrossed to the self-fertilised as 100 to 92. We thus see how
immensely superior in height the Chelsea-crossed are to the intercrossed
and to the self-fertilised plants. They began to show their superiority
when only one inch high.
