Some notes on the breeding of raspberries, R. D. Anthony {New York State 

 Sta. Bui. 417 {1916), pp. 75-88, pis. 8). — The author briefly reviews the earlier 

 work in the breeding of raspberries at the station and discusses in more detail 

 the results of crosses begun with the red, l?lack, and purple raspberries in 1910. 



The investigations have shown beyond doubt that the purple raspberries do 

 not belong to a distinct species but have originated as hybrids of the blackcap 

 and the red raspberry. Some very promising seedlings of these have been 

 secured. The work shows that improved purple varieties are more apt to be 

 developed by crossing reds and blacks than by selecting from the existing 

 purple varieties. Pure seedlings of the purple raspberry Columbian, an Fi 

 hybrid, failed to break up as much as would be expected in the Fa generation. 

 None showed any tendency to propagate by suckers, nor did any have fi'uit of 

 the color of either parent. In cane color and glaucousness some of the seed- 

 lings approached more nearly the parent types. Hybrid seedlings were pro- 

 duced by crossing two blackcaps with a red raspberry. With one cross the 

 seedlings were all purple. Among the 289 seedlings of the other cross were 

 ten yellows. 



Performance records are given for several varieties of raspberries which were 

 studied with reference to their desirability as breeding parents. A study of 

 the inheritance of color of fruit indicates that several of the black raspberries 

 are heterozygous for color and that probably several color factors are present. 

 The same thing holds with the red raspberry though the higher number of 

 yellows present would indicate fewer color factors. Glaucousness is considered 

 a dominant character. Likewise rough bark is dominant to smooth bark. The 

 factor for dwarfing appeared to be of rather rare occurrence. 



Three of the seedlings of the purple raspberry Columbian produced some 

 unusual abnormalities in the flower cluster, including gradations from perfect 

 fruits to those in which the drupelets were replaced by small, sepal-like leaves, 

 also fruits varying from perfect to entirely sterile forms which did not have the 

 leafy growth. From a correlation which was found between leaf coloration 

 and fruit it appears possible to tell all yellow raspberries from either the red 

 or purple sorts by the absence of any tinge of red on the leaves. It is sug- 

 gested that the bark of the young canes of the yellow varieties is also probably 

 entirely lacking in any touch of red or purple color. 



Notes are given on some crosses made between the flowering raspberry 

 (Rubus odoratus) and the red raspberry, blackberry, and the dewberry. Of 

 these crosses only those made with the Herbert red raspberry were brought to 

 the blooming period.
