On second thought I probably should have posted this in the breeding projects section. I decided to try and cross this red Kuri squash With this golden zucchini squash I got this From what I understand pepo and maxima not really compatable. So I guess there won't be seeds or if there are they won't be viable? I had been looking for successfull crosses of the 2 or at least something that looks similar to what to the orange football I got. Found this thread. Looks very similar.

The cross had be made this summer ? Generaly the fruits from a intra varieties cross don't change so much the native variety shape, in your inter species cross I doubt this kind of cross change native shape of the fruit too. Are you sure of the purity of your red kuri seeds ? Do you have others red kuri fruits in this plant with red kuri shape ?

The pic of the kuri squash above is on the same vine. The pic of the "football" shaped squash is the fruit that developed from the cross pollinated flower. This is the second year I've grown this kuri squash. Seed was collected by me from last years harvest. As far as im aware there are no other gardens or gardeners for that matter anywhere in my area. I'm surrounded by corn and beans for miles and miles around. This is the first year I have grown any other type of squash. I made the cross very early in the season as well. It was the first female flower on that vine and the zucchinis hadn't set fruit yet but were making female flowers. I hand pollenated the female kuri flower with a male flower I picked off the summer squash. The female flower hadn't opened fully(I did this at sunrise the flower would have opened that day if left). So I gently spread it open and inserted the anther and spun it around. Then taped the flower shut with masking tape.

Dane, Never I will suspect that this cross or anothers inter species can change the fruit shape, because the real fruits are seeds inside It's realy amazing. I will be curious to see the seeds inside, to know if they are similar to red kuri seeds shape or a mixte between your summer squash. Let us know when the fruit will be ripe

I agree. Everything I have read says that the cross pollination shouldn't change the "fruit". As I understand it tho unusual or poor pollination circumstances can cause unusual growth almost always resulting in no seeds being produced. I believe that may be the case here as I attempted pollination b4 the flower had fully opened. I too am curious to see the inside. I have thumped it with my thumb and it sounds hollow. I imagine its ripe at this point as it turned orange back in July. But I figure I will wait till the rest of the squash ripen.

Dane, if that fruit is the one you pollinated with the summer squash, then it's the seeds inside that represent the cross. If there are seeds, and they grow, try backcrossing to either parent, that is, use pollen from either the mother or father. Looking forward to seeing how it develops.

I know I just found it odd that the one I pollinated happened to be misshapen. But like I was saying earlier it was probably due to the unusual or poor pollination procedure I used.

I'm thinking perhaps my original post may be somewhat misleading. I did not mean for it to come across as the misshapen fruit was the offspring or even that the fruit was misshapen due to the cross. Just that it was strange to get a misshapen fruit from a pollination between two types of squash that are largely believed to be incompatible. As a matter of fact I honestly didn't even believe the cross would happen. I just assumed that the ovum would just abort as no compatible pollen was made available to it after I taped it shut. Sometime ago I was reading a passage from a quite old book about how field trials were done attempting to cross pepo and maxima as well as several other varieties. There was very little success between pepo and maxima something like 27 successful pollinations out 400 and 11 seeds of that and 2 that germinated but never grew out. I'll look around see if I can find again. Very interesting stuff in there tho somwhat dated

Is there something in particuliar that one expects from this interspecific cross ?

The cross is done, first I use pollen of C.mochat in C.pepo pepo flower and one hour later I added pollen of C.pepo pepo. I have read that a pollens mixture can use in inter species cross to help the crossing. next... in few days

Few news about the cross above mochata X pepo, i think pepo win, the fruit had well growing but no sign of shape changing . So I ate it ;D
