Unfertilized Citrus Seedlings?
Many of the rootstock seeds I plant come up with two shoots and have two separate taproots. Are both of these fertilized, or is one a genetic clone of the mother tree?
I am unable to obtain scion wood for many good citrus varieties here in Fiji due to strict and necessary biosecurity regulations. However, importing seeds present far less risk and, though taking longer to fruit, may enable me to grow some exciting newer varieties.
If some of the seed spouts are a genetic clone of their mother tree, how can I tell which one?
