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。

The intersexual aggression of male was significantly higher than the intersexual aggression of female and the intrasexual aggression of male. There was significant difference about male's aggression between two groups; but for female, there was no significant difference. The combat occurred intensely when two females met whether in male vs female or female vs female, but were both higher than the intrasexual aggression of male. With the increasing of meeting time, the male and female in female vs female decreased their aggression; the female in female vs male kept its aggression in high level. The component of aggression was resembled to the exhibition of aggression in every group.
同性个体间雄性动物的攻击水平显著高于同性个体间雌性动物的攻击水平和异性个体间雄性动物的攻击水平;同性个体间雌性动物的攻击水平和异性个体间雌性动物的攻击水平没有差异,但两者均高于异性个体间雄性动物的攻击水平;雄性动物和雌雌组中雌性动物的攻击行为均随着熟悉程度的增加而减弱;雌雄组中雌性动物的攻击行为在各时间段的差异不大。

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。
