Topic: Crossed french bean seeds

[Jayb]

I love a bit of diversity and thought I’d give a bit of an update on progress with my accidentally crossed french beans. I grew out another generation last year and this is what I got;


[attachment=1]

Top left are Rose Family beans looking as they should. Top right Rose Family x F1 and below the seeds of F2 plants grown 2011. All were climbers, some early and some late, there also looks to be a few reverse beans mixed in.

The second picture is another picture of Rose Family bean seeds x F2

I've also ended up with a hybidized Papa de Role, the top right shws them as they should look. I don’t have a picture of the dark F1 Papa’s I planted although they looked somewhat similar in shape to the Papa’s pictured but dark in colour with no divided pattern. 

Top right is the seed from the following harvest, Papa de Role x (F2) and below seeds from crop 2011 (F3) which gave a variety of bush and climbers and a mix of maturity times.

I love F2s as well  ;D  Have grown out and followed several here too.  A lucky French bean cross with Runnerbean is incredibly diverse (and still nowhere near stable).  A very pale yellow, early bean from a swap had one that proved to be a cross and the pollen father almost certainly was A late, long dark green purple striped bean.  The parent varieties could not be more different and the offspring is very diverse indeed.  A bought green bean with purple variety had a different one in too and that was very diverse, but all were green with purple stripes.  Seems to be a very dominant feature.

I have to learn how to upload pictures.  Thank you for showing us your 'treasures'.  Growing out odd ones is great fun, very educational and can just result in a really classy new variety in a few years time  ;D

Yes please, I'd love to see pictures they sound gorgeous  :)

Edit to add,  

Growing out odd ones is great fun  ;D

I couldn't agree more  ;D

There is a good bit in wiki re adding photos http://www.allotments4all.co.uk/smf/index.php?page=9 in FAO, although their are other image hosting sites other than the one mentioned in the link.

Another crossed one Climbing Anasazi!

[attachment=1]

Top row;  left side are Anasazi seeds as originally sown, the black seeds are from one rogue bean plant. The white coloured seeds may have been a cross or reverse. Bottom row shows the beans grown 2011 from the black and white above. All climbing beans and produced well.

[attachment=2]

Some of the pinks have pretty white splashes of colour on them, I think this is my favourite from last year.

[Jayb]

Lastly is a hybridised bean found growing last summer, should have been a bush Dog bean, seeds pictured right, but this one turned out to be a climber with red, darkening to black pods which contained black seeds! Looking forward to the scramble they produce this year

This is a runnnerbean x French bean cross flower, second generation after the cross.  Very unusual speckling, with brownish apricot coloured flowers, some light purple in the background.

[Jayb]

Beautiful, such a pretty flower. I'll follow your progress with interest  :)

These are real beauties.  Especially the pink variant!

Yes, the increased productivity is called 'hybrid vigour'.  The reason why seed companies sell F1 seeds.  Often crossed seeds are especially vigorous and higher yielding.  This will diminish a little in further generations.  The F1, the first generation after a cross, is the generation with the greatest vigour, but it is also a very uniform generation.  All the dominant features are displaying.  In the F2 generation, the generation grown from the seeds of the F1 generation, there is still a lot of vigour, coupled with the largest possible display of all the features that a particular cross can provide.  The biggest, smallest, earliest, latest, heaviest yielding, poorest yielding etc.  This is the most interesting generation and this is the generation to choose possible new varieties from.

I find this all such fascinating fun  ;D

I'm hoping my saved "red flowered" frnch beans are stable...  :)

Please do let us know what happens when you grow your F2s.  Including what the seed leaves do when they germinate.  do they stay at the base of the plant like runnerbean seed leaves or do they go a little up the stem like French beans.

[galina]

These are a few of the seed types from the F2 grow out of the cross between the early  yellow and the late green and purple bean.  All are from either one or two pods.  One type had only 3 in a pod, others had 7 and 8.  The pod sizes and seed sizes also vary greatly.  The seeds with beige/brown/gold colouring correspond with yellow or yellow stripey beans, any seeds with black patterns in them correspond with green pods.  The very plain looking non-patterned seed type (second from left top row) came from a green bean.

Yes please, love to hear more, I find it fascinating  :)

Galina, what a super variety of seeds, really intresting linking seed and pod colour. I'll try and be more on the ball with my recording next year.

What do you think the chances are of seeing the pink white splash colouration again?

I must say that it was co-incidence that I noticed  ;D  But I started putting different colour markers on them to remind myself when I came to look at the seeds.

Since these were F2s (if I have read your post correctly), there is every chance that they will come back.  The F2 generation is the generation of greatest diversity, but it is also the first generation that shows up what type the following generations will be.  The F3, F4 etc generations should be far more similar to the F2 than the F2 compared to the F1.  In theory what follows grown from the pink seeds with the white splashes, should have similar seeds, give or take a few throw-backs and split-offs.  As these are not an interspecies cross (such as between runner and french bean), there should be a good chance at maintaining this seed colour feature in further filial generations.

Here are just two of the beans I got from that cross.  The one on the right is very similar to the mother, the one on the left is shaped like the father (long with an S shape), but pale green with purple speckles, very attractive. 

[galina]

This is another F2 I got.  The pods are attractively coloured but short and lumpy looking.  I shan't carry on with this line.

[galina]

Both of these are nice.  The yellow one on the left has interesting short broken stripes and the one on the right looks a bit like the pollen father original, but paler.

This is very interesting.  The beans are so beautiful and I love the slightly tinged pods.

Thank you Ophi.

Last picture I promise.  This is a group photo.  The single bean on the right is not particularly attractive, the second from right is a straight version of the pollen father.  The third from right is so pale green, were it a squash, it would be called 'white'.  It is also particularly fleshy, a nice bean to eat.

I am calling these Infra, followed by their specific number.  The mother variety is Indiana Banana and the pollen father is Berner Landfrauen.
