Abstract

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.
