In Yogyakarta in particular the "F2" means Birds Canary results with this type of marriage F1 broodstock. For example F1 females, the results of mating with a female local male Yorkshire, with Yorkshire. In conclusion, I became too confused which one is right or wrong. Finally, I do not focus on the term, but I focus on the quality of offspring. I think even this is still a mystery, whether hereditary or walnut type that matches the race in the country. But some kind of hybrid walnut with a local Yorkshire has proven accomplishments. Are we going to stop here? I personally answer: Will Never? The last few months I think the need for blood or it can be said to be kind or in the English language is called the strain.
If we marry F1 males with F1 females, we see there is a large and some small. This is because F1 is not the Final Strain! I've written in this bulletin, how Americans are finding a new walnut species which they called the American Singer Canary, from crosses between Border and Harzer. For example walnut Yorkshire, when mated with fellow Yorkshire Yorkshire it will produce a body size has been determined.
We know the type of small split of colorbred canary (the canary called holland, which makes me confused because of the birth in Indonesia aka native citizens but holland and walnuts are the type not only in Holland and that Holland found it also not a person!), Waterslager, Harzer, Lizard, Gloster, Taiwan, Fusan (China). Major types can be said to consist of: Yorkshire, Crested, Lancashire, Norwich, Border, Scotch Fancy, Belgi Bossu. In addition there is a kind of frill or feather back and its variants are among others: Parisian frill, frill Crested Alloys, Fiorino, North / South Dutch frill. And the types of canaries rare or unknown of our society such as Munchener, Japan Hoso and others. From the picture of the types of canaries can be drawn above the words that will be crossed with small type large type, we can read what you type will be crossed, take advantage of this to cover this weakness, and others. The current confusion is kind of what should be crossed? Surely this will be answered by experiment, try and error technique must be done because Would not err is human.
Canary breeds and crosses
Many questions arise from a variety of people who asked me what it's canaries AF? What is a walnut F1? And what is meant walnuts F1, F2 and F3? What is the difference AF walnuts, F1, F2 and F3? Many answers to this question and one of them will try to answer.
First thing to understand about the "F" alone could be interpreted as a descendant. If so F1 means merupakanketurunan to 1 while F2 is the offspring to 2 and so on. However, not all offspring produced by a pair of canary breeders may say so, the symbol "F" can be used if the results obtained from the offspring crosses walnuts, which means it is derived from cross-breeding between different types of walnut.
If starting from the basic laws of this F eat actually comes from the marriage between a pair of breeding. So maybe the picture is like this
Marriage yorkshire walnut with local walnuts (walnut large with a small walnut) produced F1
F2 produced from matings between walnut yorkshire (sire of F1) with walnuts F1
Results of matings between F2 with walnut F1 produced into 3 or called F3. Another source says that walnuts can be produced F3 offspring of mating among F2
Produced from walnut F3 F4 is mated with one parent of F2
F4 offspring when mated with each other will produce offspring F4 F5. Descent into 5 or F5 can also be produced from the marriage between the F3 and F4
If the F5 offspring mated with the parent of the offspring F4 F6 and it will generate what is called a fixed strain
In addition, the breed is often called AF alien actually encountered in biological terms and may not even exist. But already the general circulation and at least necessary to explain that the walnut AF F1/F2/F3 Filial offspring resulting from (non-fixed type strain) mated to the local almonds or walnuts non-fixed strains in 3 levels ahead. In other words marriage among non-fixed strains will produce offspring called AF.
If F1 x F1 hence the term generally referred to the phenotype of AF in which heredity indukannya will be reduced.
If F1 is crossed with the local terms will be referred to as the descendants of local super indukannya where degradation of the properties will be more visible.
If the local super-crossed with the local anakannya will be referred to as a local.
Today is a lot of debate about marriage is monohybrid where walnuts are not final sesema strains mated. For example, on the subject of the name of F1 x F1 offspring, some expressed the opinion that the outcome of the marriage was called AF. In other words the marriage of same-sex non-fixed strain called AF. This assumption is reinforced by the gene theory of heredity phenotypes are more faded if a fellow non-fixed strains mated, but the filial of fixed strains (eg Yorkshire) (F) located in front of the lifter usually is as prestige and is considered higher. However, some sources also noted that the F1 x F1 F2 is called, is based on the mean Filial F is hereditary, which is it kept?
Some breeders senior told me that we should not be too concerned about this because in Indonesia itself is still in its early stages, which means half way to name the descendants of the descendants of the chain of evidence needed in detail, and detail as well as abroad. As for some of the assumptions and ambiguity of the extreme confusion that developed among the breeders and hobbyists, for example, is like this:
Birds Canary are crossed with blacktroat so-called Blacken anakannya, why do not commonly referred to as F1? This is because due to the developments canary breeders often cross strains that have been fixed or not fixed strains with blackthroat. If F1 ys x blackthroat then anakannya will be called what?
If you are a breeder who focuses on fixed strain field then maybe we can prove the regeneration chain in detail, but if not then the assumption that circulate in the community now'm not one hundred percent wrong. So every farmer must account for the results of which can then be shown ternakannya where indukannya. Since we have been referring to the approach of a dominant gene broodstock strains then fixed on his way when crossing a fellow non-fixed strains will occur confusion we have experienced now.
So it would be better if we look real on the subject of the quality of the bird itself, which include posture, voice and character.
