Characteristics and Analysis on a New Super-high Yield Germplasm HS Z6-06-56

doi:10.7668/hbnxb.2007.S2.018

Abstract

Abstract: It was showed that from a super-high yield(SHY) germplasm HS Z6-06-56 derivated from an interspecific hybridization(IH) between common wheat(T.aestivum) and durum wheat(T.durum): Dates of flagging,heading and maturing were 1,1 and 2 d earlier compared with its accepter′s parent(AB) of Shi 4185,respectively,there were no differences between traits of plant height,head length,spikelets/head by means of anova analysis.Among 3 traits composing yield heads/plant,seeds/head were same,thousand-grain weight(TGW) was the only factor caused its SHY and 27.72% advantage was found compared with AB.It was an effective method to develop wheat SHY germplasm by ways of IH heterosis.

Key words: Wheat, Interspecific hybridization, Super-high yield, Germplasm, 1 000-grain weight
