First female flower open for tetsukabuto x violino rugosa the alone plant with male flower is for this moment blue of hungary. I think this genetic is not compatible. With a parent too different the fruit accepted often to get fat but he can fall extremly easily.A fruir not totaly fecondated is tasty prepared as a zucchini.
As i had not moschata pollen i have put pollen of cucurbita maxima blue of hungary and pollen of cucurbita pepo black beauty for fecondate tetsukabuto x violino rugosa. I hope nothing of this cross but it was the alones polens availables today. The weather is humid today the fruit can accepted to get fat without viables seeds.
Unfortunately, the weather was rainy today and i have not see a lot of bees around the flowers. I have tryed a manual polinisation with a brush. What quantity of pollen is required for validated the polinisation? How much fruits can i polinisated with one male flower?
Results: on 5 plants 1 for this moment has open a male flowers. A second plant look like have viable male flowers! The cross the most able to have male flowers looks the tetsukabutos crossed with moschata. I note that the females flowers are open before the males flowers. The alone plant to have open male flowers is the less vigorous of the 5 plants. I was dont think to have so little male flowers for the second generation.
You are reason!I think the hormones available and the climate can help to determinate a gender.I think the strongs plants did less naturaly male flowers. It can gave a luck at the plants too weaks for did fruits but able to did male flowers for transmit and restorate their genetic.
Impossible: tetsukabuto will open a male flower tomorow and he has a twin male flower. I have empty a bucket with seeds of rye that i have stay take the rain.The rye contain auxin and can stimulate rhe male dlowers of tetsukabuto.A few seeds has germinate. It is the good explication of this phenomene? I will try a fecondation with tetsukabuto x violino rugosa the next flower is open in two days! It normal rhat the plant continue to did fruits with 5 fruits on the same plant?
The big difficulty for stabilisate an interspecific cross is the defiency in male flowers.Its difficult to have a male flower available the day of a female flower is open. How much time can i keep a male flower viable at the fridge?

wilscase: I'm a graduate student at Oregon State and have been working with populations segrgating for different color genes such as the B gene in Cucurbita. I'm curious if anyone has experience with crosses in Cucurbita maxima between grey blue types and orange?

wilscase: I have been backcrossing to the grey parent for 4 generations and have finally selfed the heterozygotes (for the Bmax gene) the populations have segregated for diffuse bicolor (pink/blue, orange green), blue green, blue, green, pink (salmon) and orange
Oct 18, 2022 21:36:29 GMT -5
wilscase: The genes involved are Bmax and bl. I have observed that Bmax is incompletely dominant to wild type (green). I have read that bl is incompletely recessive to Bl(wild type). I'm curious if anyone else has observed the behavior of Bmax in a grey/blue type
Oct 18, 2022 21:38:28 GMT -5
wilscase: It appears that bl and Bmax are interacting to produce different shades of salmon and pink.

wilscase: I'm also interested in any other color genetics, especially the relationships between B and L genes. In the right background these genes can dramatically increase Carotenoids (vitamin A)
