What's a 'grannie'? Is it simply an unpopped kernel?
Yup, guess my local dialect is showing again... Also called an "Old Maid".
Silt/clay, high-altitude, super-arid, sun-drenched, irrigated-desert garden. Cold radiant-cooled nights. ~100 frost free days. Grow most of my own locally adapted landrace seed. GDD10C ~1300. Buy my book or subscribe to my newsletter at Lofthouse.com.
I've always guessed it's a cross results with flour or dent. In fact, I have some popcorn crosses (mostly strawberry) that DO have dent corn dents. Floury tips are probably just a slightly less severe version (if you think about it anatomically the only real difference is a floury tip has a thin layer of hard starch over the kernel tip that keeps it from collapsing in and making the "dent")
In an extreme you'd probably wind up with what I call a "shell" kernel; a solid soft starch center with a thin hard starch cover over it. I've seen that in popcorn too.
Should post here my first year grex pop corn. Verities used - supermarket pop corn, mini black and strawberry, the last two would likely to have been grown in NZ for some time which has i believe helps give this new grex an advantage over using seed from a different parts of the planet, a combination of already acclimatized varieties. The supermarket corn's history is unknown should be GMO free at least, well thats if MPI have hopefully been doing there job it shouldn't.
Comparing mine to toomanyirons the cobs you see in the photo are long and thin where yours are a nice plump shape, this is the last pick so bit more colour because most the mini black were about two weeks behind the other two, some of the super market corn was slow to mature its cobs hence the more orange cobs .
A plate of my grow out seed which was the earliest seed to matured stage. The coloured kernels would more likely be have come from strawberry as the mini black was later maturing and so i believe it played little part in cross pollination party, when i end up growing the grex2 i'll start mini black seed off three weeks earlier in the tunnelhouse so they hopefully flower at the right time plus as well as receive pollen from the SM corn and strawberry cross. None of the later cobs of mini black had orange or even slightly orange kernels, they may well have shared there pollen but dont appear to have received any.
