Cereal Chem. 91(2):201-206The evaluation of culinary and sensory characteristics of a particular cultivar is an important trait for rice grain quality because it guides decisions for breeding programs and allows the prediction of rice market acceptance. The aim of this study was to apply direct and indirect tests for the characterization of the grain quality in a segregating rice population under different treatments (2 × 2). A methodology was proposed from the data based on mathematical equations to aid rice breeding programs in the preselection of promising genotypes. Grain samples were evaluated for apparent amylose content, gelatinization temperature, and viscoamylo-graphic profile. In addition, the samples were subjected to a cooking test. The evaluated parameters were weighted and grouped into two linear equations, yielding scores that were subjected to the selection criteria. Using this methodology, families of the studied population were preselected, which reduced the number of samples for final selection by at least 76%. The physical-chemical analysis did not indicate a direct positive correlation to accurately infer the culinary and sensorial quality of the rice for human consumption, but this analysis was shown to be useful in the preselection of lineages through the proposed strategy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
