Okay, sorry to bore everyone �� but I have been considering different approaches to breeding and have come across another bonus (i think) to using only pure A type domestic bananas in my crosses apart from bsv. The nomenclature system used for bananas by Simmonds and sheppard:
Nomenclature of cultivated bananas | News, knowledge and information on bananas
Is based on a scoring system applying points depending on whether certain traits are representative more of acuminata or balbinisia. If I use ab aab abb cultivars in my program, this is of little use. But if I use pure Acuminatas I might be able to copy their system as long as:
A: my wild species (yunnanensis/sikkemensis etc ) show uniformity at the measured points and match taxanomic descriptions.
B: the points of difference used are different between my wild sp and acuminata.
In not sure if anyone has bothered to do this before, but once my wild sp seedlings start to grow I might start taking pics as reference. It will help me confirm my seedlings are what I was told and give me a starting point. The fact I know my wild sp are all diploid as well as the ploidy and consistent A genetics of my cultivated stock should give me a reasonable chance of knowing what my first gen offspring is. I think I 'm going to breed for partheanocarpy first then back breed more to the wild sp. Given the meiosis factor, the A and Y genes will be a bit mixed with the 2nd and subsequent generations. The Y wlll be a bit A and the A will be a bit Y. This doesnt seem to be accounted for in the scoring system? Although it would simply make certain traits appear more one way than the other I guess. Also a call out. Does anyone have a source for griersonii seeds? Im trying kenibreed but its not looking good. Any help is appreciated.
