Description:
8RA4/A6 BC1, followed by individual plant selection in F2 and F3 generation. 8RA4, from a single plant selection of a restorer line with a Tamcot 788 background, followed by the selection and bulking of two plants by the multi-adversity resistance (MAR) selection procedure. A6 BC1, from a cross and subsequent backcross of BLLCABS-3-86, a MAR breeding line, with a male sterile Tamcot CAMD-E line. The F5 progeny rows were rouged for off-types and test crosses were made with male sterile germplasm to confirm the presence of the fertility restoration gene.
