Examples

  1. The genetic structure has changed due to artificial selection and genetic differentiation index indicated slight differentiation among them

  2. It also introduces the breeding strategies such as importing and creating new genotypes of dry - farming , choosing local varieties as parents , adopting convergent cross , using directional selection in adverse circumstances , selecting under dry and humid environments alternatively , practising shuttle breeding , diversifying the breeding of rust - resistant varieties , and strengthening the breeding of high quality varieties for special purposes
    提出了旱作种质引进创新,选择当地品种作亲本,采用聚和杂交,利用逆境定向选择,多生态水、旱交替选育,实行穿梭育种,多元化抗锈育种,加强优质专用品种选育的育种策略。
  3. It clearly allows us to engineer enzymes with novel functions and features by strategies , such as error - prone pcr , dna shuffling and stagger extension process ( step ) , when very little is known about spatial configuration of proteins . therefore millions of years in nature can in principle be accomplished in the test within several years . according to the basic idea of directed evolution , we modified the a - aldc gene by error - prone pcr
