Comparative Study of Physicochemical Properties of Mutant Rice Varieties Cultivated in Sindh

Physicochemical Characterization of the individual rice seed and protein analysis by SDS-PAGE electrophoresis provides useful information for the isolation and utilization of seed proteins. Rice is highly consumable food with a variety of proteins and a popular subject to mutagenesis. Four mutant varieties with their parental varieties were collected from Nuclear Institute of Agriculture (NIA) Tandojam. Physicochemical analysis including grain weight, length, width, L/B ratio, Amylose and protein content were carried out for screening of comparatively better quality characters. After quantification, proteins were separated by SDS-PAGE Electrophoresis. Analysis of results of SDS-PAGE was performed by using gel documentation system (Biorad) to find out the molecular weight of different protein fractions present in mutant rice varieties.
