Hi,
I have 1 plant that is doing great and has 1 female that has shown up. My only concern, the vines are very yellow in color. It looks like the plant is missing something or has too much of something else. A 2nd plant I have is the normal green with no issues. Therefore I am trying to figure out if this "yellow" look is normal or if I have a potential issue? Any advise or thoughts on this would be great. Thanks!

Yellow vine is said to symbolize an orange producer. The more yellow, the more orange the fruit will be. My 1044 plant has solid yellow vine, whereas another of my plants has a solid green vine. I expect the 1044 will be yellow, and the other, an ugly color.

I agree with Brad, I've read that several times on here in the past.

Green vines CAN produce orange fruit but yellow vines almost certainly WILL grow orange.

This is caused by the dominant 'B-gene' - which is 'precocious yellow'. Causes a very light-to-medium orange/ orange-yellow fruit...

There is a second dominant 'orange gene'. Called the RS gene. Vines will be green - and females will be green until after pollination. This is what gives the BigMax and Red hubbards that deep 'fire' color. Until last year, this gene had been suspected to occur in GPs - then I documented it's occurance in at least 1 'GP line'.

Both of these genes CAN and DO occur within the same plant in some 'GP lines'. Seems to give a medium shade between the two.

I have 5 (818.5 Engel) which is a (1370 Rose x self). 3 have the bright yellow vines I prefer. The other 2 are dark green. We will see which produces the prettiest.

Shannon, Please do post what you learn there. I would also be interested in if green turn out to be more hardier or are easier to take care of, vigorous, etc... Good luck with them...

Shannon, Since these are all from an inbred line.. There's actually at LEAST TWO possibilities for the difference.

#1 - the 1370 Rose was heterozygous for BOTH dominant B & RS genes.... Thus, A percentage of offspring will show 1, percentage show the other, percentage show both, percentage show neither...

#2 - the 1370 Rose was heterozygous for just B-gene. Carrying a rec. Green.. So 25% of Offspring will be homozygous B, 50% will be heterozygous B, and 25% will be homozygous Green.

There are a few other genetic combinations that could be in play right now... Possibly homozygous RS and heterozygous B - in the Rose 1370..

If you get any Greenies, I'm putting my request in early!

We are growing our 410# seed from 2000 again and it allways produces ver red/orange fruit born on dark green vines, funny the pumpkins allways start out in the Whorl as green... the 410#'s Momma was the 810 Dill.

Hey Gad, sounds like you have a true RS gene without B... How many Generations of inbreeding do you have?
