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 کاملRegeneration of plantlets from mature embryo calli of Western Ghats land race cultivar of rice, Oryza sativa L.
The Malnad region located in the Western Ghats of Karnataka is known for the cultivation of indigenous rain fed land race cultivar of rice. The present study was to investigate the callogenic and caulogenic potentialities of the two indigenous rice cultivar namely Karimundaga and Kanadatumba using dehusked mature embryo explants. For callus and shoot bud differentiation, the explants were cultu...
متن کاملEfficient Microspore Isolation Methods for High Yield Embryoids and Regeneration in Rice (Oryza sativa L.)
Through anther and microspore culture methods, complete homozygous plants can be produced within a year as compared to the long inbreeding method. Isolated microspore culture is one of the most important techniques for rapid development of haploid plants. The efficiency of this method is influenced by several factors such as cultural conditions, growth regulators, plant media, pretreatments, ph...
متن کاملCorrelation Studies in Rice (Oryza sativa L.)
Seventy genotypes of rice (Oryza sativa L.) were evaluated during Kharif 2012 to study the nature and extent of correlation among yield and yield attributing characters, days to 50 per cent flowering, days to maturity, number of effective tillers per plant, plant height, panicle length, number of grains per panicle, 1000-grain weight, grain yield per plant, kernel length, kernel breadth and L/B...
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...
