This technology discloses the origin, genetic background and relative relation of rice breeds and divides Chinese octoploid Triticale into two different types.

利用该技术揭示水稻品种的起源、遗传背景和亲缘关系，把我国八倍体小黑麦划分为两种不同类型。

The linkage character of genes Ms2 and Rht10 was transferred to CS ph1b mutant and octoploid triticale.

该两基因的连锁片段已转移到中国春小麦ph1b突变体和八倍体小黑麦中。

There are bands of Triticum and Elytrigia in Tritielytrigia, they are new octoploid types that be different from Triticum and Elytrigia.

小偃麦兼有小麦和天蓝偃麦草的酶带，是不同于小麦和天蓝偃麦草的八倍体新类型。5个小偃麦划分成两种不同的类型，中_1和中_2属于第一种类型，中_3、中_4和中_5属于第二种类型。

These microscopic characteristics of pollen grain and stomata could be used as the evidence to identify diaploid spieces and hexaploid, octoploid spieces whose chromosome ploidies are hugely different.

结论］用花粉粒和气孔的一些微观特征作为鉴别二倍体和六倍体、八倍体等染色体组倍数相差较大的物种有一定的依据。

Three pairs of elite cell lines from octoploid triticalespikes were selected for screening experiment of salt-tolerant somaclonal variants under different selection pressures.

从八倍体小黑麦的单、双倍体来自同一植株的成对愈伤组织细胞系中，选择了三对在盐分浓度不同的培养基上进行变异体筛选，并测定耐盐变异体的出现频率。

Comparison of the micro-morphological characteristics of pollen grain and leaf epiderm among diaploid Thinopyrum elongatum, Elytrigia intermedia, common wheat and octoploid Tritielytrigia types were carried out by observation under scanning electronic microscope.

方法］通过扫描电镜对二倍体长穗偃麦草、中间偃麦草、普通小麦、和八倍体小偃麦的花粉粒和叶表面的微观形貌特征进行了比较。

Efficient callus induction and regeneration procedure were established using growing tip of octoploid triticale 'h739' at glume differentiation stage as explants.Embryonic somaclones were selected.

利用八倍体小黑麦'h739'护颖分化期幼穗作外植体，成功地建立了愈伤组织诱导和再生程序，并获得了长期保持胚性的无性系。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
