In this paper, male sterile line of alfalfa was used to be improved with crossing, because the seed production of crossing is low. The affecting factors of seed production of male sterile line of alfalfa and its crossing progenies that are crossed with male sterile lines of alfalfa and good alfalfa that male is fertile were analyzed. The characteristics of female reproductive organs of male sterile line and its crossing progenies are analyzed in cell morphology. The genetic difference of male sterile line and its crossing progenies are analyzed in enzyme protein. The results showed: 1、Rate of podding of nature crossing and fecundity of artificial crossing of the male sterile plant BC1-2 that is the crossing progency of male sterile line of alfalfa and Medicago varia Martin.cv.'Caoyuan No.1'is higher than male sterile lines. Rate of podding of nature crossing and fecundity of artificial crossing of the male sterile plants BC1-19、BC1-21、BC1-22、BC1-23 that are the crossing progencies of male sterile line of alfalfa and Medicago sativa L.cv.

针对苜蓿雄性不育系杂交制种产量低的问题，采用杂交法对苜蓿雄性不育系进行改良，以原苜蓿雄性不育系为轮回亲本与雄性可育优良苜蓿品种杂交，分析苜蓿雄性不育系及其杂交后代种子产量的影响因素，从细胞形态学方面观察和分析杂交后代及原不育系在雌性生殖器官上的变异特点，从酶蛋白水平对杂交后代及原不育系的遗传差异进行分析，初步研究结果如下： 1、苜蓿雄性不育系与草原一号苜蓿的杂交后代不育株BC1-2，以及苜蓿雄性不育系与X′(苜蓿雄性不育系与新疆大叶苜蓿的杂种F1代)的杂交后代不育株BC1-19、BC1-21、BC1-22、BC1-23的天然杂交结荚率和人工杂交制种的结荚率和百粒重均高于原苜蓿雄性不育系。

Xinjiang Daye'is higher than male sterile lines. 2、The pistil characters of the male sterile plants BC1-2、BC1-19、BC1-21、BC1-22、BC1-23 are improved. Hairy cells of stigma of the male sterile plants enwrap loose mastoid cells. The area of mastoid cells exterior is larger. Hairy cells of stigma of the male sterile plants are longer and abduction.Their Style is larger and wide. The cubage of the epidermal cell is larger and the arrangement of passage cells is tight.

BC1-2、BC1-19、BC1-21、BC1-22、BC1-23的雌蕊的性状得到改良，改良的杂交后代不育株的柱头毛状体细胞将中心的乳突细胞包裹较疏松，乳突细胞明显突起且裸露面积较大，毛状体细胞较原不育系MS-4的相对长而外展且分泌物较多，；改良的杂交后代不育株的花柱较原不育系的花柱宽且长，表皮细胞的体积较大，通道细胞排列较紧密。

Through morphological analysis between male sterile plant and male fertile plant in the alabastrum period as well as in flowering period, one morphological mark was found that the alabastrum of male sterile plant was in cone shape; the alabastrum of male fertile plant was cylindraceous. The male sterile alabastrum and male fertile alabastrum were significantly different. The petal of male sterile is filiform but not lingulate and tubular , the normal one was just the opposite.

通过在蕾期和盛花期对不育系和可育系的形态性状进行分析，找到了一个与育性相关的形态标记，即不育系的花蕾呈圆锥状，而可育系花蕾呈圆柱状，二者形态差异极显著；花开放后，不育系的花瓣丝状化，没有舌状花和管状花之分，而正常可育系花序外围是舌状花，内部是管状花。

sterile：无菌

CIC并不要求完全的无菌(sterile)状态,只要清洁即可. 菌尿是否真正有伤害最重要是患者是否同时有膀胱输尿管逆流的问题. VUR之存在,菌尿造成发烧、肾炎、肾受损之机会大增,但单纯的菌尿本身并没有太大的伤害,甚至不必服用抗生素.
