Abutilons very commonly produce variegated foliage. I have 

 in front of the greenhouse at the experiment station a plant of the 

 old Golden Spirea which produces a side branch every season with 

 green foliage. If this branch was used in propagation, the plants 

 from it would have green leaves. 



Among fruits adapted to this section there are very few that 

 have come from bud variation, but there are a number of fruits that 

 have originated in this way. The currant has been known to pro- 

 duce variegated foliage, and even white fruit has been produced 

 upon the red fruiting kinds. 



The Pierce grape originated from the Isabella. Its fruit is 

 twice as large, and the foliage likewise larger and more vigorous 

 than that of its parent, and it is a popular variety in some parts of 

 California. 



The peach has been known to produce nectarines on its branches, 

 and nectarines likewise to produce peaches. Nectarines, too, have 

 been raised from peach pits, and peaches likewise from nectarine 

 pits. There can be no question but what the reason why the fruit 

 from some trees of Wealthy and other kinds of apples differs in keep- 

 ing quality and colors from the ordinary is that there is a bud varia- 

 tion ; yet many times it would be hard to distinguish this from the 

 effect of the stock upon the cion. 



The European nurseries offer a large number of plants that 

 have come from bud variations. Among them is the Variegated 

 Ash, the Cut-Leaved Beech and the Variegated Dogwood. 



These few thoughts will be enough to show that bud variations 

 do occur, and if we were on the lookout for them we would see many 

 more than we do now. 



Dr. M. M. Frisselle: I would like to ask whether the ab 

 sence of seed in the navel orange is due to bud variation? 



Prof. Green : I cannot tell about that, Doctor. I know they 

 have produced different oranges by bud variation, but whether this 

 is due to bud variation I do rtot know. I think such effects have 

 been produced. 



Dr. Frisselle : Is the seedeless grape due to bud variation ? 



Prof. Green : I don't know about that either. 



Dr. Frisselle : The currant that is sold in the stores is a 

 grape ? 



Prof. Green : Yes, that is a grape. 



Dr. Frisselle: They have been able to secure seedless raisins. 



Prof. Green : I don't know whether that is due to bud varia- 

 tion. Many have come to us from Europe, and it is difficult to get 

 at the origin. 



The President : We will suppose a certain kind of fruit is not 

 propagated for a hundred years and will not be for another hundred
