Abstract
Phytic acid (PA) is the main storage organic form of phosphorus (P) in seeds of cereals and legumes. It is a strong inhibitor against the absorption of nutrients in monogastric animals. The objective of this study was to determine the variation of total P (TP) in seeds of mungbean germplasm and investigate the inheritance of seed P compound and phytate contents. TP content in seeds of 250 accessions were found to range from 2.34 to 5.75 mg/g. The inheritance was studied in the F2 population derived from a cross between 2 accessions with the lowest and highest PA contents, viz. V1658BBR and V1141BG. Broad-sense heritability estimates of TP, inorganic P (IP), and phytate P (PhyP) contents were 80.8, 78.6 and 80.7%, respectively. The 9:7 segregation ratio of F2 population in this study indicated that high TP and PhyP were controlled by dominant alleles at 2 independent loci of major genes showing duplicated recessive epistasis.
