It is seen that in practically all cases the spurs bearing fruits with a 

 low seed value are heavier than those bearing fruits with a high seed 

 value. In the average of all varieties, the spurs bearing fruits with a 

 low seed value are 17.6 per cent heavier than those bearing fruits with 

 a high seed value. There is no apparent reason why a vigorous spur 

 should not bear fruit with a high seed value, hence it is not surprising that 

 individual lots, such as numbers 7 and 9, should show heavier spurs for 

 many-seeded than for few -seeded fruits. When the average weight of 

 spurs for a lot in which the fruit has a low seed value is approximately 

 the same as for the fruit from the same branch with a high seed value, 

 the weight of the fruit in the latter case is considerably greater than in 

 the former; this is shown by lots 4, 6, 7, 12, and 14. In those cases in 

 which the fruits are almost of the same weight for many-seeded and for 

 few-seeded lots, such as lots 3, 10, and 11, the spurs in the latter are the 

 heavier. 



In table 46 only half of the total number of spurs are considered — 

 that half containing the smaller spurs. In this table the differences before 

 noted are more marked because of the elimination in each class of the 

 half containing the heavy spurs. The smaller spurs bearing fruit with a 

 low seed value are 28 per cent heavier than the smaller spurs bearing 

 fruit with a high seed value.
