Abstract

Sorghum is an important cereal crop where cytoplasmic male sterility is exploited for hybrid breeding. Presently, A1 cytoplasm CGMS system has been well established because of the ease and stability of fertility restoration. Conventionally, genetic purity of hybrids is ensured by grow out test. In this context, DNA marker assisted selection technology offers an efficient alternative over traditionally grow out test especially in terms of time, environmental influence, space and cost-effective. Microsatellite markers are best suited for genetic purity assessment due to codominant nature.
