Abstract

MOYA, ANGELINE FLORES. 2006. Marker-Assisted Selection of IR64 Variety of Rice (Oryza sativa L.) with Introgressed Submergence Tolerance Locus (Subl). University of the Philippines Los Hafts. B.S. Biology major in Genetics. Adviser: Prof. Neilyn 0. Villa Co-adviser: Dr. David J. Mackill ABSTRACT Marker-assisted backcrossing (MAB) was utilized to introgress the submergence tolerance locus (Subl) from parent IR40931 (donor parent) to IR64 (recurrent parent). Marker-assisted selection (MAS) was used to select the varieties with introgressed Subl and favored genes of IR64. Forty-one out of 79 progenies of the second backcross (Plt 263x1R64) were found to have inherited the Subl locus. Three out of the 41 pre-selected progenies, namely 263-56, 263-46 and 263-58, were found to have the majority of the desirable IR64 traits and tolerance to complete submergence. The study recommends that these three plants undergo selfing to be able to produce progenies that have the Subl locus and complete IR64 background characteristics.
