Improvement of leaf rust resistance in bread wheat variety DWR162 (Triticum aestivum L.) through marker assisted selection

Published on

SCAR markers SCS1302 and SCS421 linked to leaf rust
resistance genes Lr24 and Lr28 used in the present study
genetically improved a bread wheat variety DWR162 using
marker assisted selection. Evaluation of BC1F2 generation
under field conditions indicated that plants with both Lr24
and Lr28 were superior in yield and its components and
leaf rust resistance. Twenty six DUS characters used for
identification of plants showed close resemblance with
recipient variety DWR 162.The availability of a combination
of the two major leaf rust resistance genes in desirable
background would encourage the genetically enhanced
DWR 162 with leaf rust resistance for its cultivation in a
large area.
