PLANT BREEDING. 



A. J. LuiJSDAii.. B.S.A., Assistant in Charge. 



The work in connection with Horticultural Plant Breeding for the year 1913 may 

 be conveniently summarized under the three main divisions of Pomology, Vegetable 

 Culture, and Floricultitre, and this work may be further subdivided under the headings, 

 the Continuation of Former Work, and the Initiation of New Work. 



APPLES. 



The plant-breeding work in pomology began early in the spring, with the choice of 

 ■suitable parent stock for hybridizing purposes as soon as the trees should come into 

 bloom. A series of crosses were made with apples, the varieties used as parents being 

 the following: Baldwin, R. I. Greening, Gravenstein, Northern Spy, Macintosh Red, 

 Wealthy, Scott Winter, Glenton, and Bingo. The last two named varieties are seedlings 

 of the Nk>rthem Spy, and have proved themselves most promising as new apples. 



The objects in view in making these crosses were as follows : To obtain an early 

 bearing, heavy yielding, good keeping, and firm apple of first-rate quality, that would 

 begin to bear fruit as early as the Wealthy or Wagener. The climatic conditions during 

 the season of blossoming were not very favourable, nevertheless a number of fruits 

 were secured from these crosses, and seed sown for spring germination. 



The following is a list of the crosses made with apple varieties :

 produced, and M. the male parent, or tree from which the pollen was secured.)
