Which seeds can't be kept? The seeds that can't be seeded are not all genetically modified seeds. To say that crops can't be used for seed retention are generally cultivated by hybrid technology. Cross-breeding has not only greatly improved grain production in agricultural production, but also promoted the development of the entire seed industry. The specific small series will be explained in detail below. 1. Whether the crop can be used for seed retention depends mainly on the breeding method, and it has nothing to do with genetically modified technology. High-quality seeds grow out of crops that are resistant to insects, disease, drought, and cockroaches, and have high yields. To say that the core of the breeding industry is how to breed seeds with good traits. At present, many excellent crop varieties are cultivated by means of cross breeding, and these hybrid seeds cannot be used for seed retention. 2. The most important reason for the hybrid breeding method is that hybrid breeding can produce heterosis. Hybrid advantage refers to the phenomenon that the progeny obtained by the two parents with different genotypes are better than the parents. To put it simply, you can make your parents like your parents, and you are their children. The performance of the progeny of hybrid progeny also needs to be analyzed in combination with the specific traits of specific organs. 3. It is impossible to say that the most successful case of modern humans applying heterosis on crops is non-hybrid corn. In addition to the hybridization advantage, corn has a relatively obvious inbreeding recession. The closer the parental genotype is, the weaker and less productive the corn is. In the early hybrid corn production, the yield of maize inbred lines was relatively low, mainly using the two crosses → four inbred lines, and the two inbred lines were combined to produce the seeds obtained after the first generation and then hybridized. The current corn hybrids are basically a single generation → two inbred lines combined to produce a child generation.
