to carry pollen from one male flower to another, it is advisable 

 also to bag or tie unopened male flowers from which the pollen is 

 to be used later in crossing. 



In from 24 to 48 hours, depending on development, the stam- 

 inate flowers whose anthers are open and shedding pollen may be 

 picked. Remove the bags from the pistillate flowers to be crossed, 

 and dust the expanded stigmas with some of this pollen. Then 

 rebag and leave for a period of 4 or 5 days. Tag or otherwise 

 mark the cross-pollinated flowers and allow the fruits to mature. 



Grow the first and second hybrid generations, and study the 

 fruits which are produced.
