Table 103 (Parent Plants)
Relative fertility of the parent plant when first crossed & self-fertile crossed & self-fertilised parent plants of the first & sometimes of the succeeding again crossed & again self-fertilised generations, as judged by the number of the fruit, or by the average number of the seeds per fruit, or by the number of the fruit & seeds both data combined. The fertility of the crossed plants being taken as 100.
