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。
