为了探讨小麦-冰草(Agropyron cristatum)衍生系3228的多粒(66～82粒/穗)特性在育种中的可利用性,本研究以3228与黄淮冬麦区5个主栽品种进行杂交,并将其杂种F_1分别种植于北京、陕西和四川,采用MINQUE(1)统计方法及AD模型对主要产量性状进行了遗传分析.在研究的6个产量性状中,均存在极显著的加性方差比率,普通广义遗传率在产量性状的遗传中所占比例较大,所有性状的遗传均存在加性和环境的互作.特别值得指出的是,3228在穗粒数方面具有极显著的加性和显性效应,在穗长、小穗数方面也具有极显著的加性效应,说明利用该种质对于提高小麦的穗柱数具有重要作用.

In order to explore the utility value of the much grains per spike of the wheat-Agropyron cristatum derivatives 3228 in wheat breeding,3228 and its hybrids F_1 derived from the crossing between 3228 and one of the five main eultivars from Huanghuai winter wheat area were planted in Beijing,Shaanxi and Sichuan,respectively.The main yield traits of the parents and their F_1 were analyzed for their dominant and additive effects by MINQUE (1)approaches and AD models.The results indicated that the main yield traits had high siginificance in the additive variance ratio,and ordinary broad sense heritability accounted for the large proportion of the yield traits inheritance.Meanwhile,the additive effects of all the yield traits were interacted by environment.On the emphasis,Grains per spike of wheat-Agropyron cristatum derivatives 3228 had high siginificance in additive and dominant effects,the same as spike length and spikelets number in additive effect,which suggested 3228 would play an important role in increasing grains number per spike in the wheat yield traits improvement.
