I'm finally getting a cross that I tried for last year but had the timing all wrong. I started some Country Gentleman seed and 3 weeks later started some Silver King. They are flowering today. Both tassels and silks are open and ready for business.
Why this cross? I'm curious what will happen when a shoepeg corn gets the se gene.
Because the genetics are a bit of a question, I am growing a limited number of plants this year and plan to backcross to Country Gentleman 2 seasons from now. Next year will see the F1 seed grown out and the next should put me into some homozygous se+ shoepeg corn. That generation will be backcrossed to Country Gentleman.

If you are using recurrent backcrossing with shoepeg you have to select again and again for homozygous se. Not easy. Have you already had experiences with this selection? Some tips for me? I want to select homo se from a cross made last year. good luck Amaury

Joseph and I had a very long thread here a couple of years ago that covers methods of selecting se+.

somewhat confusing post... It dry faster, no it dry slower, no it dry faster...
Lighter colouring kernels is probably interesting in the homogenous backgroung of a yellow clone but it doesn't work for white corn or in a OP background where you can find heaps of modifiers concerning carotene contain of endosperm.
Concerning sugar level OP background is also a drawback as heaps of modifiers (including se) can change sugar level.
Thus how to be sure to select for se... Tire ton plan
In fact, se was discovered in the early 70s and how many does seOP sweetcorn exist?
