Technique Seed Harvest So Far
First year pollinating - I appreciate the feedback/information from everyone in this community. This all started as one giant experiment I am thrilled with the results.
Here’s was my approach:
- Separate the males and harvest the pollen (duh).
- Spread the pollen out and let it dry for a few hours on a 16x12 piece of plastic (amazon).
- For pollen I planned to use, I cut it with flour (3:1 - flour to pollen). I read you can do 10:1 but that seemed excessive.
- Waited a week or two into flower when pistils were well developed at white.
- Using a #0 fine paint brush, I loaded the brush with the pollen mix and tapped the brush so it coated most of the pistils (you don’t need a lot on the brush to be effective and for this step let the pollen fall onto the pistils without touching them.
Once each site was pollinated (usually just one of the larger branches), I
went back
through and this time I “brushed in” the pollen and careful not to kick up to much pollen in the process.
Waited a few days and rinsed the plant off (not sure it was needed but helped get rid of excess pollen around the pistils and leaves).
Started checking for seeds 4 weeks later.
Seeds were harvest by hand with tweezers and all seeds were washes in cold water and quickly dried afterwards in paper towels and gently blown off with cold air.
For the first plant, the branches with seeds finished faster, so hopefully with most of the seeds gone, and those branches harvest, the plant will focus on her remaining flower.
The top three jars came from one plant (graded low, med, high based on shell color and quality). And the two below it came from another plant, whose brothers provided the pollen (similar grading process). All 5 jars are in a dark cool/dry place with the lids cracked so they can dry/cure for a few weeks before long term storage).
Hope this helps anyone new to breeding. I’m sure there are better ways, but this process worked well for me.
Cheers!
EDIT: both males that were used came from the same strain AND mother plant. I thought about keeping their pollen separate, but cross contamination on the same plant was bound to happen, so with that in mind, I just blended the two batches of pollen because the strain consistency was more important to me rather than which male made which seeds. lol
