Artificially induced genetic variation is being used effectively to supplement or complement sources of natural origin for practical plant breeding. Thus, creating genetic variation uill become increasingly important as crop genetic resources become more difficult to obtain via plant exploration. The aritificial induction of useful genetic variation offers important elements that can be used for overcoming genetic vulnerability: (1) new, previously unknown alleles can be induced in crop plant species to broaden the base of variation; (2) useful genetic variation can be induced in modern cultivars helping to shorten breeding time or to extend production "life"; (3) characteristics of existing genetic resource stocks can be improved to make them more useful in breeding; and (4) recombination in crosses may be enhanced. The performance of induced mutant crop cultivars and the successful uses of induced genetic variation in cross breeding indicate that artificial mutagenesis will play an increasingly greater role in plant breeding.
人工诱导的遗传变异正被有效地用于补充或辅助天然来源的资源，以用于实际的植物育种。因此，随着通过植物勘探获取作物遗传资源变得越来越困难，创造遗传变异将变得愈发重要。有用遗传变异的人工诱导提供了可用于克服遗传脆弱性的重要因素：（1）可在作物物种中诱导出新的、以前未知的等位基因，以拓宽变异基础；（2）可在现代品种中诱导出有用的遗传变异，有助于缩短育种时间或延长生产“寿命”；（3）可改善现有遗传资源库的特性，使其在育种中更有用；以及（4）杂交中的重组可能会增强。诱导突变作物品种的表现以及诱导遗传变异在杂交育种中的成功应用表明，人工诱变在植物育种中将发挥越来越大的作用。
