Abstract

The 1BL/1RS translocation is widespread in a large number of wheat varieties. In this study, we comprehensively evaluated the efects of the 1BL/1RS translocation on 24 traits in a recombinant inbred line population derived from the cross between 20828 and Chuannong16. The phenotypic data was from multiple environments and major loci for a given trait were excluded to avoid their interference with the efects of 1BL/1RS translocation. Comparison results showed that 1RS chromosome arm carried lines had positive efect on increasing maximum root length and spike density. While 1BS chromosome arm carried lines had positive efects on increasing plant height, grain number per spike, efective tiller, root tip number, and resistance to stripe rust. The stripe rust resistance genes, Yr15 detected on 1BS in this study and QYr.sicau-1B.1 identifed previously on 1BL were both derived from 20828. These results revealed the genetic mechanism of near-immune resistance to stripe rust in 20828 that has been utilized as a breeding parent for over a decade, and thus possibly accelerate its breeding utilization. This study combined with previous studies indicated that 1BS chromosome arm is likely benefcial to yield increase, while 1RS is more helpful for drought tolerance improvement.
