The book generation of variability for salt tolerance in rice: Scope of tissue culture,authored by Dr. T S Swapna and Dr Padma Nambisan, is an authentic record for the generation of variability in rice for salt tolerance using somaclonal and androclonal variations and identification of variants using isoenzyme markers. Generation of salt tolerant rice varieties with good grain quality and yield is very essential where salinity is a major coastal problem. Somaclonal and androclonal variation could be effectively used for tolerance generation and they could be detected using isozyme markers. Characterization of biochemical markers for salt tolerance might aid breeding programs for developing salt tolerant plants by reducing the time needed for screening.
