1. What is a sibb
2. i have read a few posts that have contradictions regarding use of selfed seed vs. crossed. having a small patch maximum 2 plants at a time i want to maximize my chances of being successful. i will be obtaining some proven crosses as well as unproved crossses and a 763 young(1502 wallacex1385.5jutras) from a selfed pumpkin. i had been planning on growing ths next season, along with a cross. any thoughts thanks jeffp

anytown U.S,A,

A sib is a sibling or a second plant. So you planted 2 seeds and have 2 plants growing from the same pumpkin. and you pollenate using the other plants pollen.

A self is when you use the same pollen from the same plant

Thanks splicer, aside from teh sibb ? specifically I am wondering about whether seed from a crossed seed is more or less relaible than a selfed seed. Several posts mention this but no specific conclusion.

There is nothing wrong with selfing.

You'll get different answers as there are many different theories involved. But problem with self, is if the desired gene wasn’t passed to the particular seed, it is less likely to be in the pollen either – basically you’ re crossing the same genes (i.e., the lack of desired genes) …. you are crossing the gene out. On the other hand, if it does have the desired gene (case of 1725 self) then it is highly likely to have desired gene reinforced in that generation’s seed. With Sib, one, both, or neither seed could have the desired gene, but you are increasing the possibility. If the gene is recessive, both mother and father must have gene (however, it can pop up in later generations when the recessive is present). If it is dominate gene, only one parent needs the gene. The characteristics of AG genes are still unknown so there is a lot of grey area. If you want to go beyond this, and you really should if you are interested, any good book on genetics will cover this and the other aspects.

I grew a pumpkin that split this year and had selfed it. It was not due to selfing that gave the one I grew a thin blossom, but rather it may have just been the unlucky one out of its batch of seeds, which were a cross. I am not going to plant the seeds, as the risk they too have inherited the thin blossom I believe to be greater.

Now if there was a line that had been selfed 3x or more, with sound interior, good color, shape, and good size potential, then I would have no reservations about the seed.

Selfing is not a bad thing, and in some cases a very useful tool.

It just helps to re-enforce a repeat of what you got already.

SW, is this the rubic's cube or pendunts square theory that I hear about all the time? No rudeness meant, but a lot (almost said most)...like I are wanting to learn...and you tossed us a lot at one time!!! Any recommendations of genetic's books for us? Peace, Wayne
