There is a GardenWeb forum for discussions about hybridizing. It is not specifically about hippeastrums, but it might be a little helpful. Here's a link:

Hi Deepak,
Could you be a little more specific as to the information you need? Is it the actual act of pollinating or what particular crosses will work? I think there is a post about the act of pollinating but I'm short on time right now & can't find it.
If you tell us the varities you want to work with I'm sure we can help. Lora

Hi Lora I want to learn the act of pollinating - step by step and would also like to learn about which varieties you can cross. Which varieties are strong to produce seeds and which to pick pollen from. Thank you.

Hi Deepak,
Sorry it's taking so long to get back but farm life in the spring is very busy. Here is a link to pollinating. I'll try to hunt up Kenneth's post with the great photos of flower parts.

Hi Lora

Thanks a lot for those links. Which part of the US are you in. Do you own a farm? What do you grow?
