Abstract

The translocation of rye (Secale cereale L.) chromatin 1RS to wheat (Triticum aestivum L.) genome has been observed to be beneficial to grain yield, but also has a negative impact on baking quality. In order to gain understanding of the influence of T1DL.1RS genotype on agronomic performance and end-use quality, F2: derived F6 recombinant inbred lines from two crosses: Kanto 107/Gabo(1DL.1RS) and Gabo(1DL.1RS)/Jaypee were tested. Grain yield and test weight of T1DL.1RS from Kanto 107/Gabo(1DL.1RS) were significantly lower than non-1RS siblings, but no significant differences were observed between T1DL.1RS and non-1RS from Gabo(1DL.1RS)/Jaypee. The effects of T1DL.1RS for quality traits were undesirable for cookie quality. The relatively smaller variation of quality traits among T1DL.1RS lines revealed the large effects of 1RS for quality traits. The range of baking traits for T1DL.1RS indicated that some of the lines had values near the mean of non-1RS lines in the Kanto 107/Gabo(1DL.1RS) background. The effects of T1DL.1RS on agronomic performance were modified by wheat genetic background, while milling and baking qualities were less affected.
