Screening of soybean germplasm for high inorganic phosphorus and low phytic acid
Keywords: Soybean, Germplasm, Phytic acid, Inorganic phosphorus
AbstractPhytic acid, is the major storage form of phosphorus in soybean [Glycine max (L.) Merr.] which comprises 75% of total seed phosphorus. It decreases the availability of some essential elements via bonding between the negatively charged phytic acid and the positively charged elements. Thus, diets high in phytate may lead to nutrient deficiencies. So, identification of lines with low phytic acid is of paramount importance. A germplasm survey was conducted among 250 soybean accessions to identify the accessions with low phytic acid. Phytic acid content ranged between 0.84 and 7.07 mg/ g of soy flour. The genotypes with low phytic acid content viz., Williams, Williams 82, CNS – AVRDC line, RKS 52 and NRC 66 may be useful in breeding programs for the development of low phytic acid genotypes with improved nutritional value to overcome nutritional deficiency syndromes and meet the demand of biofortification.
