In order to produce a good F1 hybrid variety in wheat, it is necessary to explore a new male-sterile cytoplasm and its nuclear restore gene. Four alloplasmic male sterile lines of wheat with Aegilops cytoplasm were developed to identify mitochondrial DNA variation that could potentially be associated with cytoplasmic male sterility.

在杂交小麦选育中，为了更好地利用细胞质雄性不育性，研究与不断挖掘新的不育细胞质类型及其对应育性恢复基因以改良现有不育资源至关重要。

CMS as sterile cytoplasm of-ferer and Chinese cabbage as its accepter,the alloplasmic male sterility line CMS3411-7 in Chinese cabbage have been obtained by interspecies cross and continuedbackcross with Chinese cabbage 3411-7,so 3411-7 was its maintainer line.

CMS3411-7是以甘蓝型油菜Polima不育胞质为供体和大白菜自交系3411-7杂交后，再以3411-7为轮回亲本，经多代回交后得到的含有Polima胞质的异源胞质雄性不育系，3411-7就为其相应的保持系。

主要结果如下： 1、对喷施化学杂交剂BAU9403的农大3159进行细胞学水平观察发现，花粉的发育加快，提早解体，败育发生的关键时期是花粉二核期后期。

To study the similarities and differences between male sterility induced by physiology and heredity, different male-sterile materials induced by heredity [S-type male-sterile line ms2611, ms1376] and physiology (induced by high temperature and chemical hybridizing agents SQ-1), Xinong 1376 and Xinong 2611 were used as materials, and their spikes at mononucleated prophase stage, anther and flag leaf at mononucleated anaphase stage, binucleated stage and trinucleated stage were used to conduct protein analysis.

为了研究小麦遗传型和生理型雄性不育在生化机制上的异同，以遗传型［S型不育系ms2611和ms1376］和生理型雄性不育小麦西农2611和西农1376（高温诱导和化学杀雄剂SQ-1诱导的雄性不育）为材料，分别取其小孢子处于单核早期的幼穗，单核后期、二核期、三核期的花药及旗叶进行了可溶性蛋白质的比较研究。

The research work can make us acquire the further recognition of molecular mechanism about blastocyte implantation and parturition and provide the theoretical basis for some leading-edge problems, such as organ transplantation, homeoclone or heteroclone. In the meantime, the result might be used as possible targets of medicine development for the cure of some reproductive diseases, such as sterility, abortion and fetal malformation.

研究这些关键过程将使我们对胚泡植入和分娩的分子机理获得进一步的认识，同时也可为器官移植、同种或异种克隆等研究热点提供基础理论依据，在临床上也为治疗一些妊娠疾病如不孕、流产、胎儿畸形等提供药物可能作用的靶位点。

In this article,progress in studies and utilization of special watermelon germplasm resources for branchless,dwraf,nonlobed-leaves,male-Sterility and delayed green leaf is introduced in China.

These male sterile transgenic plants with TA29 Barnase gene have the same horticultural characters which can be also inherited steadily by plants in next generation as non transgenic ones. But their flowers bear fully catagenetic stamen lacking pollens, normal fragrant nectaries and strong pistils able to receive pollens from other plants or different cultivars and set seeds. At the meantime, the sterility i...

带有TA 2 9 Barnase基因的雄性不育植株的园艺学性状与未转化植株相同，并且其性状在后代中稳定不变；不育植株的花朵表现雄蕊完全退化，但蜜腺和雌蕊健全，能接受外来花粉，杂交结实率较高；同时，雄性不育植株的不育性在后代中出现分离，不育株率占 12 。5%～ 85.7%；此外，不育性状具有镶嵌性
