What main question is what do you mean under "Ubuntu"? And, for example what is the difference for you between Ubuntu and Debian.
If you want to get knowledge about Linux kernel and it's not about Ubuntu itself. It's a shared item between all Linux distributions.
If you want to develop a software for Ubuntu, IMHO the main way is to develop for Debian and promote it to Ubuntu: http://www.debian.org/devel/index.en.html
Please also keep in mind you can help Linux even without software coding (examples: http://www.debian.org/devel/join/index.en.html)
It totally depends on how exactly you wanna help.
