杂交育种（hybridization）指不同种群、不同基因型个体间进行杂交，并在其杂种后代中通过选择而育成纯合品种的方法。杂交可以使双亲的基因重新组合，形成各种不同的类型，为选择提供丰富的材料；基因重组可以将双亲控制不同性状的优良基因结合于一体，或将双亲中控制同一性状的不同微效基因积累起来，产生在各该性状上超过亲本的类型。正确选择亲本并予以合理组配是杂交育种成败的关键。英文：Hybridization breeding refers to different populations, hybridization between different genotypes, and in its progenies by selecting and breeding method of homozygous varieties. Hybridization can make parents gene re combination, form a variety of different types, provide abundant material for selection; gene recombination gene can be excellent parental control were combined in one, or the same trait controlled parents in different genes is accumulated, the type in all the characters more than parents. The correct selection of parents and be reasonable matching is the key to the success of the hybrid breeding.
