Marker-assisted backcrossing to improve terminal drought tolerance in pearl millet uri icon

abstract

  • Several alternative marker-assisted backcrossing (MABC) procedures are described that can be used fortransferring quantitative trait loci (QTLs) from a donor to an elite recurrent parent when these two lineshave been used in forming the base mapping population. We describe ICRISAT?s experience to date inusing these methods in pearl millet (Pennisetum glaucum (L.) R. Br.). We are attempting to improveterminal drought tolerance of elite inbred pollinator H 77/833-2 using donor PRLT 2/89-33, and eliteinbred seed parent maintainer line ICMB 841 using donor 863B. The advantages and disadvantages of thealternatives are discussed
