摘要: 试验对水稻广亲和材料间,广亲和与籼、粳品种间,以及广亲和与籼型恢复系间的杂交组合进行花药培养,用花粉植株(HO)与雄性不育系测交,通过考察测交种的农艺性状、结实率与产量,同时筛选出亚种间强优协组合及其父本。该方法可在两年四季完成一个育种周期,是水稻亚种间杂种利用研究的新途径。

Abstract: Pollen-induced plants H0 from hybrid combinations of intervarieties of wide-compatibility materials. W.C. varieties×indica or iaponica varieties, and W.C. varieties×indica restorer lines in rice were test-crossed with male-sterile lines. The strong heterosis combinations and their W.C. lines or W.C. restorer lines were selected by testing the yield and the setting rate. This method only spends two years or four growth seasons in completing the breeding circle. and is a new path of researcnes on intersubspecific hybrid rice.
