Just collect pollen and turf the plant...
Let the flowers develop...wait till you have a fair number of flowers, then shake the pollen off on to a mirror or piece of glass..Make sure you clean glass awhile before hand with isopropyl alcohol to degrease and be sure it evaporates...you can scape the pollen up with a razor blade after its had a few hours to dry..then take a bit of ordinary baking flour ( a teaspoon or so )and put in the microwave for 15-20 second to dry out.
Once you've dried the flour..mix about 6 parts flour to one part pollen...The flour will act as a desiccant and keep the pollen dry...
What I do is go to the organic food store and buy a bunch of those gelatin caplets that pharmacies use...load up a bunch of those caplets with your pollen mixture and seal...In turn you will also want to put those caplets into something airtight as well (with little air space left over)...Be sure to add a dessicant pouch that you find from a shoe box or electronics you may have purchased to the container ...then put in a freezer somewhere..try to limit temp fluctuations...
Pollen should last a good year...When you want to pollenate a female..Take one caplet out, let it adjust to room temp for a few hours (important..as it limits condensation on pollen when opened)..maybe even put in little ziplock as it warms...then paint it on female flowers over a couple days...
Once caplet is opened it is pretty much done..hence I make a bunch of caplets..
Good luck..better than having to keep a male
