花生栽培种遗传基础狭窄,虽然品种间杂交迄今仍是花生育种的主要手段,但国内外花生育种工作者已普遍认识到,花生育种要取得突破单纯依靠常规杂交已越来越难,鉴于花生野生种遗传多样性、丰富性,对各种生物、非生物胁迫具有抗性,而且具有高产因子,因此认为通过远缘杂交技术利用花生属野生资源特别是花生区组以外的不亲和野生种是拓宽花生栽培种遗传基础、选育突破性品种的有效途径。花育44号是山东省花生研究所利用不亲和野生种
Although the genetic basis of peanut cultivars is narrow, so far the crossbreeding between varieties is still the main means of breeding peanut. However, peanut breeders at home and abroad have generally recognized that it is more and more difficult to make breakthroughs in peanut breeding based solely on conventional crossbreeding. Therefore, it is considered that the use of wild peanut resources, especially peanut groups, by incompatible wild species through distant crossing techniques is Broaden the genetic basis of peanut cultivars and breed breeds effective way. Huayu No. 44 is a peanut institute of Shandong Province that uses incompatible wild species
