Today I planted F1 hybrids of [South American Synthetic Composite X Astronomy Domine]. That's flour/flint/dent corns from South American crossed to North American sweet corns. I planted around 30 sibling groups. Along the edge of the patch I also planted a few sibling groups of sweet corn kernels of F2:[Cateto X LISP Ashworth].
I also planted sweet kernels of F2:[Cateto X LISP Ashworth] next to a patch of the same seed that I planted about a month ago.

I have a silver dime just itching to be spent on orange sweet corn when you have enough available to share Joseph.

Many of the plants from F1 hybrids of [South American Synthetic Composite X Astronomy Domine] are currently flowering and are around 8 feet tall.

I like the shoepeg trait. Especially in red! It looks quite exotic! Joseph, that's some nice looking corn you have there! How is your cherry flavored corn project coming along?

How is your cherry flavored corn project coming along? adopted that project and has really developed a nice strain. I'm calling it Steev's cherry sweet corn these days, even if he seems reticent about my doing so. |

I also planted sweet kernels of F2:[Cateto X LISP Ashworth] next to a patch of the same seed that I planted about a month ago. I harvested the first cob of this corn yesterday... (66 DTM). It was only about 18" off the ground, so I picked it for the sake of denying it to skunks. It was super tasty and very sweet. I shared some with 2 friends saving about 1/2 the cob for seed. Then I took it home and measured brix: 23%. Woo Hoo! Looks like it is sugary enhanced. The LISP Ashworth is 50% sugary enhanced, so it looks like the gene lottery favored this cob. |

Just starting to get the first ears from my South American corn hybrids from last year. I had two SA types last year. I crossed some Coroico/Pirincinco with my White Flour Grex and Cateto Sulino with my flint corn population. All my SA corn selections are generous gifts from maicerochico. From the few ears I've gotten as a sample, crossing the 8-row white flour with the Coroico seems to get you a 10-row corn. This picture has the White Flour on the left which was the pollen parent, a fairly representative Coroico ear in the middle (female parent) and my best so far ear of the hybrid.  The hybrid does not show as good tolerance to Northern Leaf Blight than the female parent did, which is not too surprising considering the White Flour Grex is highly susceptible and it is another very bad year for NLB. |

Have you got any pictures to show the differences in resistance oxbow?
I grew both Hopi Blue and Abenaki Rose this year. The Abenaki Rose stalks and leaves are haggard looking compared to the Hopi corn. I've seen some lodging in it too, none in the Hopi so far.

Oxbow, Coroico's row condition (partially interlocked, as shown above, or fully interlocked) is a completely recessive trait. I have seen it crossed with Bloody Butcher, Cuzco, and Hickory King, and the interlocking trait always disappeared in the F1 ears. Higher row numbers and various degrees of interlocking will segregate out in later generations. The Coroico's strong resistance to NLB is polygenic and non-strain-specific, which is probably why your F1s are more susceptible (White Flour Grex parentage drug down the average). You'll have to reconcentrate those resistance genes if you want to have the high level of tolerance that you saw last year. Two generations of inbreeding with intense post-tasseling selection pressure (best 15%  ) would work very well. It's a shame that, unlike rust, NLB tends not to be terribly symptomatic before anthesis. |

Again: what I posted in the "Northern Leaf Blight" thread.

Here is what a cob from F2:[Ashworth X Cateto] looks like compared to Astronomy Domine. The color is much darker in the cateto. After tasting about a dozen of these high-carotene cobs, I decided that I really like the taste of carotene in my corn. I like it in muskmelons and squash also.  |

Good looking corn and. from what you say, good taste and nutrition.

Just for giggles I planted a row of Cuzco Morado over behind the barn where the cows hay feeder sits in the winter. Here's the tallest stalk that hasn't been blown over yet.  Some really impressive prop roots. This plant has six rings, but only 3 of them reach the ground.  Most of the patch tasseled about a month ago. The earliest about two months ago. First plant had an ear with silk emerging today 19th of September. I didn't expect to get seed, but I had tried stressing a few the plants by root binding them in small pots to see if I could induce them to tassel earlier and cross with a locally adapted flour corn. Not sure that I managed to achieve that or not. |

I finally got a photo of the high-carotene sweet corn in which the color balance is about right... The top cob is from Astronomy Domine showing typical endosperm color from ordinary sweet corn. The bottom cob is F2:[LISP Ashworth X Cateto]. I roasted a bunch of this corn last night. Mmm. Mmmm. Mmm.  |
