So the variety of L21 andLainong9217 should be planted in dry land of high yield,and the variety ofLainong8834 and YD27 in dry land of middle yield,and gaining high yieldand high efficiency.2 The researches on the flag leaf and root system senescence after anthesisand yield were studied in dry land wheat of high yield,the activity of super-oxide dismatase and catalase、and the soluble protein content、Cytokinincontent in wheat flag leaf and root system after anthesisand Cytokinincontent in grain decreased slowly,and the content ofmalondiadehydeand the Abscisic Acidcontent in wheat flagleaf and root system and the Abscisic Acidcontent in grain increasedslowly,meanwhile keep higher root vigor and the root vigor decreased slow-ly,the result would be benefit to delay the senescence and gain high yield.3 The effects of soil thickness on the senescence of flag leaf and root sys-tem、nitrogen distribution and utilization and water consumption law andyield in dry land wheat had been studied in soil column and field.

通过大田条件下旱地高产小麦耗水规律及产量变化的研究表明，4个品种耗水量、产量、水分生产率、籽粒产量中来自花后光合器官输送的比例及综合效益评判结果均以鲁麦21和莱农9217为高，而莱农8834和烟D27则与此相反，因而在旱地高产麦田应以种植鲁麦21和莱农9217为主，中产麦田以莱农8834和烟D27为主，以获得高产高效。2在旱地高产大田对鲁麦21与烟D27两品种花后旗叶、根系衰老及产量变化进行了研究，认为花后旗叶与根系SOD、CAT活性、可溶性蛋白质含量、i-PAs含量及籽粒iPAs含量降低缓慢，MDA含量、ABA含量及籽粒ABA含量增加缓慢，同时保持较高的根系活力且下降缓慢，有利于延缓衰老，形成高产。3土层厚度对旱地小麦花后衰老、氮素分配利用及产量的影响进行了研究，随土层厚度加深，根系活力、根系与旗叶SOD、CAT活性及可溶性蛋白质含量增加，MDA含量减少，土层愈薄，其根系与旗叶衰老愈快。

The results were as follows, the total cultivated area of Liaoning province has declining tendency in recent 26 years, the total grain yield and the grain yield per unit area increased in "wave" style; the grain yield per unit area and total planting area had the great effect on total grain yield, and the effect of yield per unit area on total grain yield is bigger than that of planting areas; the yield and the planting area of different crops also affected total grain yield greatly, and maize, rice, durra, wheat affect the total grain yield by grain yield per unit area, while millet, maize, wheat affect the total grain yield through planting area changing.

得出如下结论，辽宁省近26年粮食总播种面积呈下降趋势，粮食总产量和平均单产受气候条件影响呈波动式增加；粮食总播种面积和平均单产均显著影响着粮食总产量的变化，并且粮食平均单产的变化对总产的影响要大于粮食播种面积的影响；各种作物的产量和播种面积变化都影响粮食总产量的变化，但各种作物对粮食总产量影响的方式不同，其中玉米、水稻、高粱和小麦主要是通过单产的变化影响粮食总产量，谷子、玉米和小麦则是通过播种面积的改变来影响粮食总产量的变化。

A year ago, this lush coastal field near Rome was filled with orderly rows of delicate durum wheat, used to make high quality Italian pasta.

就在一年前，这块靠近罗马的海边田地还茂盛地长满了一行行整齐有序的精细小麦，这些小麦用来制作高品质的意粉。

At the basis of previous analysis, we choosed the Durum Wheat as the research target and carefully designed the research methods. The bioinformatics research of the target was carried out subsequently.

在此基础上，精心设计研究路线和方法，选取硬粒小麦Durum Wheat为研究对象，综合利用生物信息学手段，对硬粒小麦Durum Wheat中可能存在的硒蛋白进行了探索性研究。

Furthermore, 13 Italian durum and 20 bread wheat cultivars and 11 Chinese wheat cultivars were also tested at seedling stage with 10 Italian isolates of pathogen.

在田间成株抗性监测中，12.2％和58.9%的硬粒小麦品种和面包小麦品种分别表现抗病或中抗；在苗期抗性鉴定中，参试的很多中国品种对大部分意大利菌株表现免疫、近免疫或高抗。

Furthermore, 142 accessions could be divided into three major groups using the clustering analysis, indicating that the gliadin variations among durum wheat were associated with their geographic origin.

高分子量谷蛋白电泳共分离出14种亚基和15种亚基组合，但是优质亚基所占比例不高，这可能是因为硬粒小麦加工用途的特殊性，使得多年的育种并未太多改变硬粒小麦高分子量谷蛋白亚基等位变异的频率，促成优质亚基的累计。

Wheat and durum were taken as acceptors and the DNAs of 7 different plant materials were taken as donors, authors had studied seed-bearing ratio of modern generation plants transformed by pollen tube pathway. The results were shown as follow.

以普通小麦和硬粒小麦为受体、以亲缘关系不同的7个材料作供体，研究了花粉管通道法转化植株的当代结实率。

" Pasta:Any of several starchy food pastes made from semolina, the purified middlings of a hard wheat called durum."

意大利面：用粗粒小麦粉，即经过净化的硬质小麦的胚乳，制成的淀粉类食品。

Durum wheat is tetrapolid (28 chromosomes) and contains two basic genomes, whereas common bread wheat (Triticum spp.) is hexaploid and contains three basic gonomes. Durum is best adapted to growing in arid regions of the world: Italy and other areas in Southern Europe; Turkey and Syria in the Near East; Morocco and Algeria in Africa; Soviet Union; and Canada and Northern United States in North America.

多伦小麦产品是四倍体(28个染色体)并包含两个基本基因组，而普通的面包粉是六倍体并包含三个基本基因组，多伦小麦可以很好的适应生长于世界上的干旱地区环境，例如：意大利和南欧一些地区；近东的土耳其和叙利亚；非洲的摩洛哥和阿尔及利亚；前苏联；以及北美洲的加拿大和美国北部。

WestBred's seed varieties portfolio will encompass durum wheat in the Southwest United States, feed barley and wheat in the Northwest, hard red and hard white winter wheat in the Central Plains and soft red winter wheat in the Eastern United States.

westbred的种子品种的投资组合将包括硬粒小麦在西南地区，美国，饲料大麦和小麦在西北地区，硬红和硬白冬小麦，在中部平原和软红冬小麦在美国东部。
