黑麦属

With rye cultivar AR71 as the source of resistance to wheat sharp eyespot,we tried to transfer the rye resistant genes into eight wheat cultivars or lines by pollen tube pathwaymethod and intergeneric crossing between wheat and rye.

以抗小麦纹枯病的黑麦AR71为抗源供体，以鲁麦1号、有蜡、百农3217、圆锥小麦TG29等8个小麦品种为受体，试图通过花粉管通道法和属间杂交的方法，导入供体的抗纹枯病基因。

The self-fertile trigeneric hybrids between Triticum aestivum L.(2n=6x=42;AABBDD) and Agropyron michnoi Roshev.(2n=4x=28;PPPP) F1 hybrid (CM,2n=5x=35,ABDPP)with two rye (Secale cereale L.,2n=2x=14;RR)cultivars, Wugong 774 and AR132 were produced.

普通小麦(Triticum aetivum L。，2n=6x=42；AABBDD)和根茎冰草(Agrop yronmichnoi Reshev。，2n=4x=28；PPPP)间的F1杂种(2n=5x=35；ABDPP)与两个黑麦(Secale cereale L。， 2n=2x=14；RR)品种杂交，产生了自交可育的三属杂种。

We used triticale which was the allopolydroid of wheat and barley as the brewing beer material.

首次采用了小麦与黑麦属间异源多倍体杂交品种——小黑麦作为酿造啤酒原料。

Triticale is an intergeneric cross between wheat and rye.

黑小麦是小麦与黑麦之间的属间杂交种。

It suggested that the species or subspecies of Hordeum were genetically related to rye and wheat, which also belong to the tribe of Triticeae, while rice was related to maize.

以玉米为外类群，采用邻接法进行系统发育关系分析发现，同属于小麦族的大麦属植物、黑麦和小麦间亲缘关系较近，而水稻与玉米则相对较近。

The sequences of psbL-psbJ region were compared with that of rye Secale cereale L.

同时，将大麦属psbL～psbJ区序列与已报道的黑麦Secale cereale L。

In the barley, the oats, the triticale and three awn grass, the success ratio of these primers respectively was 73.2%, 82.9%, 87.8% and 85.4%, and some primers even still appeared specificity strip bands in particular plant, These results indicate that the SSR marker coming from the wheat gene set is highly transferable among species in different genus of Pooideae.

所选取的41对引物在大麦、燕麦、小黑麦和三芒草4种供试植物中的扩增成功率分别为73.2%，82.9%，87.8%和85.4%，有些引物在特定植物中还会出现特异性条带，以上结果表明，从小麦基因组上开发的SSR引物，在早熟禾亚科不同种属植物间有较高的通用性。

Three common spring wheat cuhivars, eighteen winter wheat and three relative rye cuhivars introduced from different regions of China were used for RAPD analysis.

采用随机扩增多态性DNA对来自我国不同生态区的21个普通小麦品种以及3个小麦近缘属栽培黑麦品种的遗传差异进行分析。

The seed set frequencies ranged from 0.001% to 0.184%.The chromosome number of F2 plant root tip varied from 39 to 56.4 In the Fa progeny of wheat *AR7l, Some plants showed higher alien translocation frenquencies.

在小麦与黑麦AR71属间杂种的F_2中，个别植株发生了较高的异源易位频率，其中有1株(229-3植株)产生了多达3个异源易位。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
