Abstract/Description: | Samba Mahsuri (BPT5204) is a medium slender rice variety highly popular among the farmers in South and Eastern India. It is one of the best Rice varieties with good cooking quality. The yield of BPT 5204 is 6-6.5 tons/ha, even though it is showing maximum susceptibility to many biotic stresses and exhibits incomplete panicle emergence, this make it an ideal genotype for identifying mutational changes in traits of agronomic importance. To obtain agronomical important traits mutation breeding plays an important role. Mutagenesis plays key role among these genetic resources, mutant stocks with discrete genetic lesions are essential to determining gene function and dissecting biochemical and metabolic pathways. Chemical mutagenesis has been routinely used to generate genetic variability for breeding research and genetic studies. In rice, there are several advantages of using chemical mutagenesis to produce mutant populations suitable for both forward and reverse genetics. First, mutant populations can be produced using any genotypes. Second, because of the high density of mutations, genome-wide saturation mutagenesis can be achieved using a relatively small mutant population [1, 2]. Third, it provides a large allelic series as a complement to the knockout mutants produced by insertional mutagenesis or transformation methods (over- and under-expression) [3-6]. Morphological variations including grain types, maturity and traits contributing to yield are observed in every generation. In present study, observed the agro-morphological variations in the BPT-5204 sheath blight tolerant mutants which developed through chemical mutagen EMS (Ethyl Methane Sulfonate) [7]. |
