Performance of short-day onion genotypes for nutritional quality traits of bulb

Abstract

The experiment was conducted to evaluate the short-day onion genotypes for quality attributes during kharif 2017. Among thirty genotypes evaluated, the highest reducing sugars were recorded from the genotype COHBON03 (3.83%). The highest non-reducing sugars were recorded from the genotype COHBON08 (3.52%). The highest total sugars were recorded from the genotype COHBON03 (6.45%). The highest pyruvic acid content was recorded from the genotype COHBON17 (2.31 μmol/g). These genotypes can be used for commercial cultivation with high non reducing sugars, since those genotypes having high non reducing sugars and high pungency could have longer storability. Furthermore, these genotypes can be used as parental material in the quality improvement of bulb onion.
