Abstract

Phytic acid (Myoinositol 1, 2, 3, 4, 5, 6 hexakisphosphate) is a ubiquitous compound present in plants. It is an important constituent in seed reducing the bioavailability of phosphorous and mineral nutrients when fed to monogastric animals like swine, poultry, fish etc. Hence, identification of maize germplasm with reduced phytic acid content is imperative to formulate the breeding programs to evolve low phytate lines. Towards this, three hundred and thirty-eight maize germplasm accessions available at Department of Millets, TNAU, were raised and screened for phytic acid content which varied from 2.77 to 16.70 mg/g of seed. Based on the variability present, a reference set with fifty-eight genotypes for phytic acid was formulated. The reference set was formed with random genotypes selected from the base population to follow a normal distribution (skewness; 0.17, kurtosis; 0.61 and K-S test for normality Dn = 0.70) for phytic acid. The non-significant difference between the means of the base and the reference ensured the entire representation of the base in the formulated reference for phytic acid. Among all the lines in the reference set, the lowest phytic acid content were observed in the lines UMI-113 (2.77 mg/g) followed by...Continue Reading
