通过对普通小麦(T.aestivum)、四倍体硬粒小麦(T.durum)种间杂交超高产新种质HS Z6-06-56性状表现分析表明:该种质与受体亲本石4185相比,挑旗期、抽穗期及成熟期分别提早1,1及2 d,株高、穗长、小穗数三性状等同于受体。在产量构成三因素中,株穗数、穗粒数等同于受体,方差分析差异不显著;千粒重是构成该种质超高产的主要因素,本试验中单项指标超受体幅度达27.72%。利用种间杂种优势,是创造小麦超高产新种质的有效途径。 Through the analysis on the traits of HS Z6-06-56, a new cross between the T.aestivum and T. durum interspecific hybrids, it showed that the germplasm and the receptor parent 4185 1, 2 and 3 days earlier than that of heading date, heading date, heading date and maturity respectively. The characters of plant height, spike length and spikelet number were the same as those of recipient. Among the three factors of yield formation, the number of panicles per panicle and the number of panicle per panicle were the same as those of the receptor. There was no significant difference in ANOVA among them. Thousand grain weight was the main factor that contributed to the high yield of this germplasm. The use of interspecific heterosis is an effective way to create new high yielding wheat germplasm.
