通过普通小麦与六倍体小黑麦杂交、多元回交和花培纯合 ,将小黑麦抗条锈基因导入普通小麦 ,获得了 12个在成株期对小麦条锈病菌流行小种免疫的新种质 ,其中 8个新种质在苗期对流行小种高抗。研究普通小麦与六倍体小黑麦的杂交特性结果表明 ,六倍体小黑麦×普通小麦与普通小麦×六倍体小黑麦两种杂交方式都有较高的杂交结实率 ,但前者种子发育好 ,出苗率高 ,后者种子胚乳发育不良 ,出苗率低。用普通小麦进行回交 ,可获得一定的结实率 ,种子出苗率较好。
Triticum aestivum was introduced into common wheat by crossbreeding of common wheat with hexaploid triticale, multiple backcross and flower culture homozygous, Of the new germplasm, of which eight new germplasm in the seedling stage of the races of high resistance. Studies on the hybridization characteristics of common wheat and hexaploid triticale showed that the hybridization rate of both hexaploid triticale × common wheat and common wheat × hexaploid triticale had higher seed setting rate, Good seed development, emergence rate is high, the latter seed endosperm dysplasia, emergence rate is low. With ordinary wheat backcross, can get a certain seed setting rate, seed germination rate is better.
