Abstract:

The present study disclose the nutritional characteristics of high and low resistant starch (RS) containing maize (Zea mays L.) genotypes and determined in order to identify different correlations between them. A set of 5 high and 5 low RS containing selfed maize genotypes, mostly hybrids of public as well as private sector widely grown and analyzed for the carbohydrate profile (amylose, amylopectin and starch), protein, oil, ash and crude fiber content. The results revealed significant variation for amylose and amylopectin in both high and low RS containing maize genotypes. Amylose content showed highly significant positive correlation (r = 0.546 and 0.550, p < 0.05, high and low RS containing maize genotypes, respectively), whereas amylopectin showed highly significant negative correlation (r = -0.546 and -0.550, p < 0.05, high and low RS containing maize genotypes, respectively). Protein content was positively correlated with RS (r = 0.321[high RS] and 0.311[low RS], p < 0.05) and amylose (r = 0.454 [high RS] and 0.464 [low RS], p < 0.05) in both high and low RS containing maize genotypes. Oil and crude fiber content also showed positive correlation with RS and amylose content in both high and low RS containing maize genotypes, whereas the starch and ash content were not altered significantly in both high and low RS containing maize genotypes.
