How to tell which kind of pigeons are good and can be used as breeding pigeons?

Using pigeons with characteristics as breeding pigeons is to pass on their excellent genes, and each generation is stronger than the next, which is a good breeding pigeon. He should have an excellent gene bank, which means a qualitative leap from point to surface. Is there a real all-around pigeon in absolute sense? The answer is no, gold is not enough, people are not perfect, and pigeons naturally have no absolute omnipotent pigeons. Pigeons that win the championship in sunny days, win the horse in cloudy days, lead in mountains, excel in plains, are short, flat and fast, and have both long-range and speed do not exist. Every pigeon always has its own adaptive race distance, race route and race season. It is impossible and unrealistic to be perfect. We can't ask pigeons to be omnipotent, but we must make strict requirements on the characteristics of breeding pigeons, that is, an excellent breeding pigeon must have unique excellent genes in its body. Breeding pigeons can be divided into the following categories: 1, short-distance absolute fast pigeons: The advantage of this kind of pigeons is the race distance within 400Km, which has good impatience and explosiveness, good performance on the plain race line and poor overall performance in bad weather. This kind of pigeon may be. Its speed index: 80~90, endurance and toughness index 10~20. 2. Middle-distance fast pigeon: The advantage of this kind of pigeon is the race distance within 700Km, which is better than the "short-distance absolute fast pigeon" and has certain adaptability to complex race routes and bad weather. In the 500~600 km race, the plain race line with good weather often gains something, but the ranking is not high. In the case of bad weather or mountain race, give full play to your advantages, that is, endurance and explosiveness, and leave those sunbirds far behind. Its speed index: 60~80, endurance and anti-stress index 20~40. 3. Long-distance fast pigeon: The advantage of this kind of pigeon is the race distance of more than 700Km, which has certain adaptability to mountain and plain race lines and strong adaptability to bad weather. This kind of pigeon is the king of the distance and the elite of the overnight race. They are hard-working, with iron will, perseverance and lasting endurance. Its speed index: 50~60, endurance and anti-stress index 40~50. The above three kinds of pigeons basically cover the blood of most celebrities in the world. Even if they are of the same bloodline, there are great differences between individuals, so we should carefully study and analyze which kind of pigeon we belong to. Then choose each breeding pigeon according to its own characteristics, so that breeding can achieve good results. It's not completely unreasonable to "cut the knife and fold it easily". After many generations of "short-distance absolute fast pigeons" are merged with the same type of pigeons, a drop of blood of "medium-distance fast pigeons" will be properly mixed to improve the stability of their old pedigree, but the speed will not decrease; In the breeding of long-distance fast pigeons, skillfully introducing a drop of blood from medium-distance fast pigeons will appropriately increase their speed without affecting their original stability. So there must be a distinction between primary and secondary. At that time, Zhan Sen's "semi-Huapuli" made Zhan Sen pigeons' achievements advance by leaps and bounds, more like a live fish stirring a stagnant pool, and he was just a drug primer, just like a catalyst in chemical experiments. However, although the combination of "long-distance fast pigeon" and "short-distance absolutely fast pigeon" is risky, there are also many successful examples. As the saying goes, looking down is an abyss, looking up is a blue sky.
