I received some "Ashworth sweet corn" seeds this spring from the Long Island Seed Project. The description of the seeds said something like they were inter-grown with sugary enhanced sweet corn.
I soaked the seeds for about 24 hours in water. 9% of the seeds were soft and squishy after soaking (perhaps implying that they are homozygous for the se gene.) [Yes I know that less than an hour ago I claimed that I can't really know for sure what the genome contains just by looking at physical traits.]
I planted around 100 of them this spring and have back-crossed them this summer to sugary enhanced sweet corns. I would be tickled with 9 plants homozygous for se. (Hoping it's more than that since I attempted to select for se+ before planting and what I worked with today are the culls. The selection criteria was based on having more finely wrinkled kernels.)
Regards, Joseph

I found some description of this CV here : www.liseed.org/corn.htmlI think next year I'll grow a mix of all these early corns : - Lisp Ashworth "fortified" (su + se), - Astronomy domine (mix), - Golden Bantam (su), - Early June (su) - and one very precocious and very tasty su called Spirit (su, 68 days) from Syngenta. I will let wind control the pollination but I'll try also some controlled crossing (with bags on ears and tassels). The problem with all these early cv is that ears are quite small. Does anyone knows an early sweet corn cv that gives big ears ? I'd like to cross it with these small cv. I'll grow also the less precocious cv like Double red, Mirai and serendipty triple sweet

LISP Ashworth is considerably earlier than Astronomy Domine. For best success at crossing, I recommend planting the Astronomy Domine first, and when it is about 5 cm tall plant the Ashworth. (I think of Ashworth as a 60 day corn, and Astronomy Domine as a 75 day corn.)
I haven't done further work on pulling a homozygous se+ population out of the LISP Ashworth.

OK thank you Joseph I'll do that.
Any idea for big early ears ?
