采用“籼粳架桥”技术,以籼粳基因适度搭配协调,交换重组,生态选择,培育偏籼偏粳骨干亲本。C418与广占63S两个高产、优质、广适性、高配合力的骨干亲本的育成与应用,丰富了“籼粳架桥”科学内涵。文章还进一步讨论了籼粳杂种优势及优势生态群利用问题。
The indica-japonica bridging technique was used to coordinate the compatibility of indica and japonica genes, exchange recombination and ecological selection, and to cultivate the parents of partial parents with partial japonica parents. C418 and wide accounting for 63S two high yield, high quality, wide adaptability, high combining ability of the backbone of the parent breeding and application, enriched “indica japonica bridge ” scientific connotation. The article further discussed the indica-japonica heterosis and the use of dominant ecological groups.
