Characterization of submergence tolerant backcross derived lines of an elite rice variety Rajendra Sweta

Abstract

The present research work entitled Characterization of submergence tolerant backcross derived lines of an elite rice variety Rajendra Sweta was undertaken on the backcross populations developed through Marker Assisted Back-crossed introgression of submergence tolerant Sub1 QTL from donor parent Swarna Sub1 to Rajendra Sweta, a well-adapted, high yielding and preferred rice variety of Bihar state in order to remove its bottleneck of submergence susceptibility. Total of 5 best homozygous plants out of 32 BC2F2 with maximum morphological similarity to Rajendra Sweta were selected to carry out background selection. newline
