| dc.description.abstract | Micronutrients are required in small quantities but play a vital role in various processes of human body. The intake of nutrients in daily diet is far from satisfactory and largely less than 50 % RDA (recommended Daily Allowance) is consumed by Indian population. Unavailability of the essential and vital micronutrients in plant based food may be due to either low content of nutrients or presence of anti-nutritional factor (ANF). One among the ANFs the phytic acid presents in all cereals, pulses and oil seeds. Phytic acid chelates cations like Zn2+, Fe2+, Ca2+ and Mn2+, makes them unavailable form. In this context made an attempt to develop mutant for low phytic acid line in leading variety. Chemical mutagen, 2 % (v/v) EMS was showed LD50 in GPU-45 variety. The mean phytic acid content in M| seeds ranged from 190.2 to 210.7 mg per lOOg of seed. In wild plants the mean phytic acid content was 202.1 mg per lOOg was observed. In this study the 530 core germplasm lines of finger millet were assessed for their phytic acid content in grains. There is a huge variation in phytic acid content and it ranges from 60.2 to 517.7 mg per lOOg. The 20 contrasting genotypes for phytic acid were analysed for zinc and iron content. Study showed distinct pattern of correlation with phytic acid. Zinc showed high significant correlation with phytic acid and high significant negative correlation was observed with phosphorus. Iron was not correlated with the phytic acid and inorganic phosphorus. All the four characters, zinc, iron, phytic acid and phosphorus are showed a good correlation between GCV and PCV and all are highly heritable. The SSR two rice markers RM 3542 and RM 482 were did not show polymorphism between low and high phytic acid types of finger millet. | en_US |
