Validation of QTL for grain weight using MAS-derived pairs of NILs in bread wheat (Triticum aestivum L.)

Near isogenic lines (NILs) are ideal material for a variety of genetic studies including validation of specific QTL. In the present study, eight pairs of NILs for grain weight were developed, seven in the background of Raj3765, and one in the background of K9107. For this purpose, marker-assisted selection (MAS) was used for the transfer of three grain weight QTL (QGw.ccsu-1A.2, QGw.ccsu-1A.3 and QGw.ccsu-1B.1) that were earlier identified in...
