Creation of Crosses mul Hybrids 21 



blended by artificial crossing so guarded as to exclude 

 the pollen of all varieties other than the one desired. 



The process is very simple, and with bisexual flowers 

 is conducted as follows: The corolla is opened artifi- 

 cially before the anthers are ready to burst and distrib- 

 ute the pollen. The stamens are carefully removed 

 without injuring the pistil, and a light paper bag is 

 carefully slipped over the flower to prevent access of 

 pollen from other flowers. The flower from which the 

 pollen is to be used is also protected in the same 

 manner. As soon as the pollen in the flowers of the 

 plant is ripe or ready for distribution and the pistil 

 ready for its reception, that from which the pollen is to 

 be used is carried to that from which the stamens have 

 been removed, its pollen gathered on a delicate camel's 

 hair brush and gently deposited on the stigma of the 

 pistil. This flower is again protected from access of other 

 pollen until the day's inflorescence has been completed. 



The seed from the ovary of the pistil thus treated, 

 being the combined and exclusive production of these 

 two varieties, will produce a new variety having the 

 qualities of the two parents blended in a new individual. 



Selection of seed from ideal plants, blending in the 

 highest degree the good qualities of the parents, will be 

 necessary for several generations of the offspring to 

 perfectly fix the type desired. This practice relates to 

 crossing varieties bearing bisexual flowers. In the case 

 of monoecious and dioecious plants, the pistils and 

 stamens appearing in different flowers, the same process 

 is pursued except that there wall be no stamens to be 

 removed.
