漸滲現(xiàn)象（漸滲雜交） ：是通過雜交或其后代與某個(gè)親本回交，遺傳物質(zhì)從一個(gè)基因庫被引入另一個(gè)基因庫的現(xiàn)象。 - 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

百科釋義
Introgression, also known as introgressive hybridization, in genetics (particularly plant genetics) is the movement of a gene (gene flow) from one species into the gene pool of another by the repeated backcrossing of an interspecific hybrid with one of its parent species. Purposeful introgression is a long-term process; it may take many hybrid generations before the backcrossing occurs.
