Carthlicum, and was located on region of wheat chromosome 2AL near the gene Pm4b, it maybe either Pm4b, or a new gene linked to Pm4b. Temporarily, the gene was designated as PmPS5A. A dominant major gene conferring resistance to powdery mildew was identified in a BC〓F〓 population derived from a cross of amphidiploid Am9 and wheat cv. Laizhou953. The gene originated from T.

通过与含有已知抗病基因品种或品系的对该20个菌株反应模式比较和系谱分析，推测Am9／莱州953*〓 F〓含有Pm4b，波斯小麦PS5含有Pm4b与一个未知抗病基因组合；（DR147／Ae14）／／莱州953*〓 F〓和硬粒小麦DR147含有Pm4a和一个未知抗病基因组合；尾状山羊草Ae14和小伞山羊草Y39含有新的抗白粉病基因。

The chromosome composition of Yuan Zhong 2, a common wheat-Ag.intermedium partial amphiploid (2n=54), was analyzed with the genomic in situ hybridization,in which the biotinylated total DNA of Ag.intermedium as the probe and the total DNA of common wheat cv.Chinese Spring as blocking DNA were used to hybridize with the chromosome DNA of Yuan Zhong 2 at mitotic metaphase in root tip cells.

为分析普通小麦-天兰冰草部分双二倍体-远中2号(2n=54)的染色体构成，用生物素(biotin-16-dUTP)标记天兰冰草染色体组DNA作为探针，以普通小麦品种中国春染色体组DNA为封闭DNA，与远中2号的有丝分裂中期染色体DNA进行了分子原位杂交。

An artificial amphiploid RSP (2n=42, AABBDD) obtained by tetraploid landrace Ailanmai (Triticum turgidum L., 2n=28, AABB) and Aegilops tauschii (DD, 2n=14) expressed high tolerance to preharvest sprouting which derived from Aegilops tauschii.

利用长休眠的河南节节麦与四倍体小麦矮兰麦杂交幷经人工加倍合成的新六倍体小麦RSP，其节节麦抗穗发芽特性得到表达。

An artificial amphiploid RSP (2n=42, AABBDD) obtained by tetraploid landrace Ailanmai (Triticum turgidum L, 2n=28, AABB) and Aegilops tauschii (DD, 2n=14) expressed high tolerance to sprouting which derived from Aegilops tuuschii.

"RSP"是利用长休眠节节麦与四倍体小麦杂交并通过染色体加倍，人工合成的优良的抗穗发芽小麦新材料。

In order to master the occurrence of wheat leaf blotch and evaluate resistance of wheat cultivars in Henan Province from 2005 to 2007, 49 wheat cultivars were selected and their resistance to wheat leaf blotch were identified.

在自然发病条件下，系统调查了河南省主栽小麦叶枯病在2005年－2007年的田间发病情况，并采用自然病圃法鉴定了49个小麦品种对叶枯病的抗性。

Mature embryos of wheat from cultivar EM12 in Hubei province and mode variety Bobwhite were used as target materials.

以湖北省小麦品种'鄂麦12'和模式品种'Bobwhite'为材料，成熟胚为转化受体，优化基因枪转化法的轰击压力、轰击距离、选择剂等因素，建立以小麦成熟胚为转化受体的高效转化系统。

There was significant positive correlation between photosynthetic rate and leaf chlorophyl content, increasing the phosphorus application is beneficial to increasing leaf chlorophyl content and net photosynthetic rate.

叶绿素含量与光合速率呈显著正相关，增施磷肥有利于提高小麦叶片的叶绿素含量，从而提高小麦叶片的净光合速率。

Chemical nitrogen fertilizer applied was an absolutely necessarily technical and measure in red soil region for the purpose of improving quality of corm and wheat. The impact of chemical nitrogen fertilizer on quality of corm and wheat was better than that of organic nitrogen fertilizers.

为提高红壤旱地玉米和小麦子粒的品质，使用化学氮肥是一项必不可少的技术措施，同时化学氮肥对玉米和小麦子粒品质提高效果大于有机氮。

The results showed that the wheat growth was increased with lower concentration of Cu; but with higher concentration of Cu, the activities of diastase and the mitotic index of root tip cell of wheat were reduced, the content of pro was increased.

朱云集等研究了Cu对小麦根系生长发育及生理特性的影响，指出随Cu浓度的提高，小麦胚根、次生根条数减少，根系SOD与POD活性呈下降趋势[7]。

These data indicate that it is feasible to establish universal primers and transferable EST-SSR markers between monocotyledonous and dicotyledonous crops.

22对白菜/油菜EST-SSR引物中，有18，21和22对引物分别在大豆、小麦和玉米中有扩增产物，可扩增率分别为81.8%，95.4%和100%；其中分别有10对和7对引物在单子叶作物小麦和玉米及双子叶作物大豆和油菜中的扩增产物显示多态性，有7对引物在4种作物中的扩增产物均显示多态性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
