Morpho-physiological Performance of Selected Somaclones (SC) Which were Produced in Vitro Salinity Stress in the Field for Two Sequential Years
2015
The experiments were carried out at the farm of Bangladesh Sugarcane Research Institute Ishurdi, Pabna, Bangladesh during 2009-2010 and 2010-2011 cropping seasons for the production of somaclones in vitro to select salinity tolerant lines of sugarcane. Sugarcane varieties Isd 28, Isd 35, Isd 36, Isd 37 and Isd 38 were used for selection of salinity tolerant lines. Different levels of salt were used with MS medium for in vitro plantlet regeneration. The in vitro selected somaclones were evaluated in the field for two sequential years. Somaclones SC4, SC7, SC8 of Isd 28, SC1, SC7, SC9 of Isd 35, SC4, SC6 of Isd 36, SC3, SC9 ,SC10 of Isd 37 and SC3, SC7, SC8 of Isd 38 performed better in morpho-physiological performance at field condition in two sequential years. So those lines should be considered as salinity tolerant lines for further study.
