I've got a few other varieties of field peas to try if this lot don't work out, Kaspa and Parafield from memory. I think it is a desirable characteristic for field grown peas to help prevent lodging, so probably not that remarkable that the Austrians have selected for this trait. T Alan Kapuler liked it. Several of his varieties have this trait. On its own (definitely with tall peas) it is not enough to prevent peas from falling over, but it is useful and less tying up is needed. Yes, record keeping is good. I sometimes fall down and think I remember and of course I don't. Therefore I try and be disciplined and write everything down now. When I developed Court Estate Gold, I had to go back to old emails I had sent to a friend to remember all the steps. Luckily I had taken photos. First few pea flowers have opened here - getting there. I don't believe that you would have partially pollinated any cross Templeton, because if your flower had already produced pollen it would be very obvious to the naked eye. I sometimes wonder whether I am doing the right thing when I do not cover the flower after crossing, theoretically bees could bring in some other pollen afterwards. I really started doubting my crossing method when two F1 plants of the same cross (from the same pod) looked different. One looked purple, the other partially purple podded. By the end of the season both had much greener pods and those early very dark pods on one of the plants had a little green in them all the same, when I studied photos later and looked for it. Should I worry? I find it can be difficult to fix a marker on hand pollinated pea flowers because they are so brittle and break off easily. I would find it near impossible to fix a blossom baggie or the like. And I have never understood how fixing a bit of cotton wool works (I'm sorry I can't remember who suggested this). Cutting into the flower and leaving the outer petals intact would be the best method perhaps, if I wasn't so clumsy with the tweezers  in the first place. Keep the progress reports coming.  |

galina, the JIC pisum database gives the following for af"Leaflets converted to tendrils. Associated with branching. Stipules are not affected." Unless the branching genes have something to do with its appearance, i don't know what is going on. T Just had a look on the JI site and can't say I understand. Certainly don't understand what is meant by 'associated with branching'. In which way? Looked on the linkage group at other features and was none the wiser either. I'm sure someone on here understands this stuff. There is of course the possibility that your numbers are not large enough for proper statistics and that your lower rate is just a blip. |

Galina,
I have partially crossed a flower -I had done a cross the right way - dominant pollen to recessive mother - and the F1 plants showed both dominant and recessive characteristics on different F1plants, my only explanation was that partial pollination had taken place when i did the cross. Didnt think of subsequent pollination - i dont bag pea flowers.
for marking crossed flowers i clip calyx lobes off on opposite sides of the flower with my forceps. These show up even when the pod is drying off, so a good way of refinding the crossed pods. After trying scalpels and tweezers i invested in some cheap curved forceps from an entomological supply house online. I also tag the flowers with aluminium tags that can be embossed with ballpoint, and attached with a soft copper tie they are supplied with. I connect these to the main stem immediately below the flower, and clip off any other flowers at that inflorescence so only the clipped calyx flower remains. I also write each cross in a stud book. I still lose stuff...
and flowers are just beginning to open here too, in the green house. Autumn growouts can be a bit tricky, depending on a bit of luck to find the Goldilocks sowing moment, and then crossing fingers for good weather in the pod dry down stage. Im trying a big 40 plant greenhouse growout for the first time, with about the same number out in the garden, which seems to be a week or two behind.

Yep, JIC is not crystal clear to my amateur eyes...
I'll post some pics of the tendril ones tomorow, hard to do from this tablet, as with the dodgy typing:)
