84 MINNESOTA STATE HORTICULTURAL SOCIETY, 



Strrnvherries. — The crossing work was all carried on at the 

 Experiment Station. The following crosses were made : 



Alaska x Dunlap. Dunlap x Pocomoke. 



Dunlap X Seedling No. 8 Dunlap x Native Wild. 



Dunlap X Alaska. Native Wild x Dunlap. 



Dunlap X Sheppard. 



The Alaskan variety produced only a scant supply of flowers, 

 but the flowers had a good amount of pollen. 



The best time to gather pollen was found to be at 9 a. m. 



The Sheppard is usually an imperfect variety, but some of the 

 flowers were perfect. Among the wild strawberries there are also 

 found perfect and imperfect varieties. 



The method of emasculation and pollination used was as usual. 

 Paper and cheese cloth bags were used. The paper bags in a few 

 instances induced rotting of the fruit. 



Out of 229 flowers of Dunlap crossed with Alaska, only 112 set 

 fruit, or about 48 per cent. 



Of eighty-seven flowers of Dunlap crossed with native wild, 

 fifty-three set fruit, i. e., 61 per cent. 



Of fifty-nine flowers of Dunlap crossed with Pocomoke, thirty 

 set fruit, i. e., about 50 per cent. 



Dunlap crossed with Seedling No. 8, four flowers ; three set fruit. 



Wild crossed with Dunlap, ten flowers ; six set fruit. 



From about 100 flowers of Alaska crossed with Dunlap, only 

 two berries were produced, or 2 per cent. One of these was stolen, 

 but the other was saved and from it we raised thirty good seedlings. 



Blackberries and Dewberries. — Of these the following crosses 

 were made : 



Ancient Briton x Hoyt's Dewberry. 



Fluke's Hybrids x Hoyt's Dewberry. 



Ancient Briton x Native Wild Dewberry, 



Hoyt's Dewberry x Ancient Briton. 



Hoyt's Dewberry x Fluke's Hybrids. 



Of all the flowers crossed, only from 15 per cent to 20 per cent 

 set fruit, and they ripened much later than the general crop, even 

 though the crossed flowers were the first ones to appear. 



Raspberries. — Of these the following crosses were made : . 



Loudon X Wild Red Native. Columbian x Ancient Briton 



Loudon X King. Columbian x Loudon. 



Loudon X Columbian. Wild Red x Columbian. 



King X Columbian. Columbian x Wild Red. 



King X Loudon. Cumberland x Columbian. 



Wild Black Cap x Columbian. Cumberland x Loudon. 



Columbian x King. Wild Red x Loudon. 



Columbian x Cumberland.
