Efficient in vitro plant regeneration via leaf base segments of indica rice (Oryza sativa L.).
A reliable and reproducible protocol has been developed for high frequency plant regeneration from 4-5 mm long leaf base segments of 4 days old in vitro germinated seedlings of indica rice (Oryza sativa) cultivar Rasi. The effect of age of seedlings, position of leaf base segments and optimum concentration of 2,4-D on callus induction frequency was investigated with a future aim to use leaf bas...
متن کاملGenetic Diversity Assessment of Rarely Cultivated Traditional Indica Rice (Oryza sativa L.) Varieties
Random amplified polymorphic DNA fingerprinting was performed to assess the genetic diversity among rarely cultivated traditional indica rice (Oryza sativa L.) varieties collected from a tribal hamlet of Kerala State, India. A total of 664 DNA bands amplified by 15 primers exhibited 72.9% polymorphism (an average of 32.3 polymorphic bands per primer). The varieties Jeerakasala and Kalladiyaran ...
متن کاملPlant Regeneration in vitro by Organogenesis on Callus Induced from Mature Embryos of Three Rice Varieties (Oryza sativa L. ssp. indica)
Callus induction and regeneration in vitro of three rice varieties (Oryza sativa L. ssp indica), Bg 94-1, Moraberekon and Bg 300 were examined. Phenotypic variations of regenerated and parent plants were compared and the method of plant regeneration was confirmed by histology. Callusing was induced by culturing the mature embryos of the three rice varieties in a liquid medium of distilled water...

متن کاملProtocol for in vitro somatic embryogenesis and regeneration of rice (Oryza sativa L.).
Development of highly efficient and reproducible plant regeneration system has tremendous potential to provide improved technology to assist in genetic transformation of indica rice cultivars for their further exploitation in selection. For the development of a highly reproducible regeneration system through somatic embryogenesis, mature embryos of highly popular rice cultivars i.e., Govind (fo...
