Genotypic Variation in Pigeonpea for Protein, Dietary Fibre, Fatty acids and Lectins

Six genotypes of pigeonpea viz., Bahar, UPAS 120, MAL 13, NDA 1, BSMR 853 and ICP 7035 were evaluated for their soluble protein, dietary fibre (cellulose, hemicellulose, lignin and pectin), fatty acids and lectins. Pigeonpea genotypes contained soluble protein in the range of 20.13 to 23.35%. The genotype ICP 7035 and UPAS 120 contained significantly high soluble protein in their seed. The cellulose and hemicellulose in different genotypes of pigeonpea was in the range of 3.12 to 3.70% and 1.16 to 3.31%, respectively. ICP 7035, MAL 13 and Bahar had lowest lignin as compared to other genotypes. ICP 7035 also had lowest hemicellulose and total saturated fatty acids and highest polyunsaturated fatty acids (PUFA) and total unsaturated fatty acids (TUFA). Pectin in grain was present in the range of 2.89 to 4.82%. BSMR 853, NDA 1, ICP 7035 and UPAS 120 had higher pectin than other genotypes. Haemagglutinating activity (lectins) of pigeonpea grain was varying in the range of 1205 to 1415 HU/g.
