Investigations on somaclonal variation in ginger were focused on induction of variability through in vitro techniques, evaluation of somaclones for morphological, yield and quality attributes, reaction to soft rot and bacterial wilt diseases and characterization of selected superior somaclones using RAPD markers. Protocols for indirect organogenesis, indirect embryogenesis and in vitro mutagenesis were developed in ginger. Field evaluation of already regenerated bud culture derived somaclones of two ginger cultivars viz. Maran and Rio-de-Janeiro were undertaken for three seasons from 2002 to...
