Fukushu/Calamondin/Meiwa hybrids

[martweb]

Normally it is not the best idea to use Fukushu, Calamondin or Meiwa as mother, but it seems possible. How high or low is the percentage of true hybrids when pollinated?

I have pollinated into Calamondin and was successful in getting Hybrids, from one pollination.
About 50/50 Hybrids and Non Hybrid seedlings. Some weak hybrids produced.
One reason I chose Calamondin is that it is very reliable in setting and holding fruit, rare to drop fruit here.
That meant good chance of recovering mature seed.
Secondly my pollen parent was Microcitrus, so the final plant is Trigenic, Microcitrus X Fortunella X Citrus.
I have also got some interesting slightly variable seedlings of Calamondin over the years, not hybrids, but not 100% true to type. Possibly Zygotic.

The Merdaka Lime is a Calamondin X Hystrix hybrid, not sure what direction that cross was, but both are highly nucellar.

Years ago I grew 2000 plus Meiwa seedlings, hoping to get a variant or variegated or anything different.
Not one variant was found, in leaf shape, vigour, thorns. etc.
That said, I would still consider using it as a seed parent. Again it is reliable in setting and holding fruit.
