中文摘要：

采用MINQUE统计方法、加性-显性（AD）及其与环境互作的遗传模型,对粘类小麦雄性不育系和恢复系杂交F1小穗两边结实数、中间结实数等结实性状进行了分析。结果表明,粘类小麦雄性不育系育性恢复性主要以加性效应为主,其次是显性效应,加性方差占表现型方差的比例变幅为38%~48%;不育系（V）-90-110、（Ven）-90-110、（K）-224、（V）-224所配制的组合,在2个结实性状上,包括国内法、国际法,平均结实率均具有正向显著或极显著的加性效应,亲本5253、02-7-215、00-6-247、M8003具有使不育系恢复度提高的加性效应;双亲加性效应高的组合多数表现出其显性效应比较差;国际法恢复度高的组合（K-224×5253）,究其原因是双亲国际法恢复度的加性效应高,尤其亲本5253国际法恢复度的加性效应在供试材料中是最高的,其显性效应也较高（36.14%）;粘类小麦雄性不育系杂交结实率的高低与环境的互作相对较小,育性恢复性在年份间的表现比较稳定。

英文摘要：

Some seed set characters of genetic variances,such as seed set in both sides、seed set in the middle of F1 spikelets from sterile lines and restoring lines of Nian group（with Ae.kotschyi,Ae.variabilis,Ae.ventricosa and Ae.bicornis cytoplasms） in wheat for two years are analyzed by the genetic model of additive-dominance（AD） and their interactions with environments by MINQUE（1） approaches.Additive effects was the main behavior to the fertility restoration performance of male sterile lines of Nian group in wheat（the range of additive variance to phenotype variance were 38%-48%）,and the next was the dominance effects.The seed set characters of some combinations from sterile lines（V）-90-110,（Ven）-90-110,（K）-224,（V）-224 had positively significant or the most significant additive effects,the parents 5253,02-7-215,00-6-247,M8003 had the additive effects of making the restoring degree increased.In general,the combinations with higher additive effects of two parents were lower in dominance effects.The restoring degree of international method was high,because the additive effects of the restoring degree of international method of two parents were high,especially the additive effects of the restoring degree of international method for 5253 was the highest in all materials,and its dominance effects was higher（36.14%）.There was small interaction between the environment and the rate of seed set of male sterile lines of Nian type in wheat,fertility restoration performance was more stable between years.
