Estimation of amylose, protein and moisture content stability of rice in multi locations

Abstract

Rice quality is measured of the rice grown on different five locations by an auto grain analyzer. Auto Grain analyzer works on the Near-Infrared transmittance (720 - 1100 nm). Protein, amylose and moisture contents of the rice samples of 9 fine lines were tested. Different environment tested entries were evaluated and found that all the values have highly significant effect of environment and genotypes. The environment and genotype ranking in the Additive Main effect and Multiplicative Interaction (AMMI) model were studied and PK8680-13-3-1 and check variety Basmati 515 were found most stable lines in most micro environment with respect to amylose contents and moisture contents. Protein contents were studies in PK8892-4-2-1-1 and PK3810-30-1 are best suited in the all environments. The results indicated that grain analyzer may be used for Amylose and Protein contents and effect of different locations on these traits in early breeding generations for quality control in the food industry. Key words: Rice, environment, amylose, protein, auto grain analyzer.
