Preliminary study on the genetic improvement of rice japonica restorer line by introgression of international rice breeding germplasm
利用國際水稻品種資源改良粳稻恢復系研究初探 -
Abstract : the main characters and seed set of bc1 ， bc2 ， bc1f2 from ms line back - crossing with the pollen of hybrid rice were studied. the appearance of a large number of self fertile plants in ms line was analyzed. the effect of introgression of restoring genes on ms line purity and hybrid yield in indica and japonica rice was discussed. it was pointed out that “ iso - cytoplasm restorer line ” was seriously reducing the purity of ms line and that hybrid rice was unsuitable for isolation zone in the seed production fields
文摘:研究了雜交稻花粉對母本不育系回交後代群體bc1 、 bc2 、 bc1f2的主要農藝性狀和育性表現，分析了不育系中出現大量自交結實株的原因，討論了恢復基因滲入對秈、粳不育系純度和雜交稻產量的影響，指出「同質恢」對降低不育系純度的嚴重性和雜交稻作制種田隔離區的不合理性。 -
