CIMMYT synthetic hexaploid wheats were employed to cross with rye for evaluating the crossability of SHWs and screening SHWs with high crossability for distant cross. Great variation of the seed set percentage was observed among 102 SHWs ranged from 0% to 72.49%. Of 102 SHWs, 11 ones possessed the crossability higher than 50%, and one (YAR/Aegilops tauschii 518) had a similar crossability as Chinese Spring.

利用102份从CIMMYT引进的人工合成六倍体小麦与黑麦杂交，分析了人工合成六倍体小麦的可杂交性，结果表明：人工合成小麦的可杂交能力变异很大，从0%~72.49%；其中有11份人工合成小麦的可杂交率超过50%以上，1份人工合成小麦YAR/Aegilops tauschii 518的杂交结实率达到72.49%，与中国春相似。

Data from the seed set percentage of SHWs with common AU genome donor and different D genome donor or common D genome donor and different All genome donor, indicated that factors on both donors (Durum wheat and Aegilops tauschii) affected the crossability of SHWs.

通过比较同一个硬粒小麦与不同节节麦或同一个节节麦与不同硬粒小麦的可杂交性，发现硬粒小麦和节节麦都对人工合成小麦的可杂交性具有较强的作用。

A set of spelt monosomic lines as female parent were respectively crossed with wheat new variety SM96 and new line SM20005 to determine the chromosomal location of the gene conferring resistance to powdery mildew in both. Seeding of parents, F〓 and F〓 from monosomic F〓 were inoculated with race no. 15 of Blumeria graminis f. sp. tritici. Analysis of obtained data revealed that one major dominant resistant gene originating from wild Emmer in the variety SM96 and the line SM20005 was located on chromosome 4A.

为确定小麦新品种沈免96和新品系沈免20005含有的抗白粉病基因所在染色体，以一套斯卑尔脱单体系为母本分别与沈免96和沈免20005杂交，将亲本、F〓、单体F〓植株的F〓代群体在苗期用小麦白粉菌15号小种的单孢菌系接种鉴定，单体分析结果表明，沈免96及沈免20005所含源于野生二粒小麦的抗小麦白粉菌15号小种的1个显性主效基因位于4A染色体上。

Among them, strains of Bacillaceae occupied the predominance with 59.1% in various wheat organs. Oxytetracycline resistant strains of Bacillus licheniformis were isolated from wheat rhizosphere, root and stem indicating their high abilities of spreading. Opportunistic human pathogenic bacterial strains with oxytetracycline resistance such as Bacillus cereus and Stenotrophomonas sp. were also isolated from various wheat organs. No oxytetracycline resistant bacterium could be detected from wheat seeds.

土霉素抗性的Bacillus licheniformis在小麦根际土壤、根、茎等器官中都分离得到表明该抗性菌种在小麦内生系统中具有较高的传播性；具有土霉素抗性的人类机会致病菌Bacillus cereus和Stenotrophomonas属的细菌在小麦的根际土壤、根以及叶子中也均分离到，但是在小麦种子中没有分离到任何土霉素抗性的内生菌。

1D-SDS-PAGE eletrophoresis and molecular markers were employed to survey the Waxy proteins and Waxy genes in 312 winter wheat cultivars and lines from Chinese winter wheat and U.S.A. and Austrilia, 60 lines selected from the cross of Baihuomai and Norin 67 which was detected preliminarily to be waxy wheat with Iodine-dyeing-seed-section , 120 F2 plants from cross of Lu935031(Jimai19) and Yumai 47 . Amylose content and RVA properties were also recorded. The major results were presented below:1 The components of waxy protein subunits could be detected precisely by 1D-SDS-PAG Eelectro- phoresis.

以国内外冬播小麦品种312份、从白火麦×Norin 67中选育出经碘染籽粒剖面初步鉴定为糯性小麦的品系60份以及鲁935031×豫麦47的F2代120个单株为材料，利用1D-SDS-PAGE电泳技术研究了Waxy蛋白亚基组成，并利用分子标记检测了相应Waxy基因；检测了部分材料的直链淀粉含量和RVA特性等，分析了国内主要麦区小麦淀粉特性；结合生化标记、分子标记和淀粉特性三者各自的优势，探讨了快速、准确、简便筛选具有优良淀粉品质的小麦资源和品种的途径。

The results showed that, using transient GUS expression, the frequency of resistant calli and shoot differentiation as a criteria, wheat mature embryos were cultured on the preculture medium of CM4C1P for 14 days, and immersed in inoculation suspension Ⅰ for 3 hours, then the explants were co-cultured under desiccation conditions for 3 days, which was optimal conditions for Agrobacterium-mediated transformation of wheat mature embryos.

为了进一步完善根癌农杆菌介导的小麦遗传转化体系，以小麦成熟胚为转化受体，研究了根癌农杆菌介导法转化小麦的主要影响因素，结果表明，以gus基因瞬时表达率、抗性愈伤组织获得率和分化率为转化指标，小麦成熟胚在预培养基CM4C1P上预培养14d后，用侵染培养液Ⅰ侵染3h，再经干燥共培养方式处理3d，是根癌农杆菌介导成熟胚转化的合适条件。

Nitrogen also increased the rate of wheat yield of intercropping single for Gao Yu, reflecting the presence of wheat intercropped with nitrogen from the beans to the transfer of wheat, resulting in intercropping conditions decreased the sensitivity of wheat to nitrogen fertilizer.

同时施氮增加小麦产量的幅度以单作高于间作，这反映了在小麦蚕豆间作体系中存在着氮素由蚕豆向小麦的转移，导致在间作条件下小麦对氮肥的敏感性下降。

The results shoed that after spraying 1 and 5 mgL^(-1) of anthraquinones, the photosynthetic rate raised by 38.03% and 39.73%, chlorophyll content increased by 3.53% and 3.83%, and MDA content decreased by 11% and 23%, respectively. The anthraquinones could absorb solar UV radiation, and convert the harmful UV into blue or yellow light which can promote plant photosynthesis. It as suggested that foliar-spraying appropriate concentrations of aloe's anthraquinones could promote wheat photosynthetic activity, alleviate UV harm, and thus, increase wheat yield.

结果表明：在灌浆期用浓度为1和5mgL^(-1)的芦荟蒽醌类物质喷施小麦，光合作用速率分别提高了38.03%和39.73%；叶绿素含量分别提高了3.53%和3.83%，丙二醛含量分别降低了11%和23%；蒽醌类物质能够吸收太阳中的紫外线，并将紫外线转换成能促进光合作用的蓝光或黄光；芦荟蒽醌类物质能促进小麦光合作用效率，减轻紫外线对小麦的损伤；喷施合适浓度的芦荟蒽醌类物质能够提高小麦产量。
