Biochemical constitutes of different cotton ( gossypium hirsutum ) germplasm

The present investigation was carried out at Main Cotton Research Station, Navsari Agricultural University, Athwa farm, Surat during 2016. Protein, phenol, gossypol, reducing sugar and tannin were analyzed from Gossypium hirsutum germplasms. Our study revealed that out of 12 cotton varieties, high protein was found in genotype 8 (Full okra leaf) (0821-B4-11-7), low in genotype 7 (Red thick leaf and red flower) (IAN-1327). High phenol was observed in genotype 10 (Small leaf and medium ball size) (C-1622, low in genotype 12 (Big ball size) (Demeter 111(1)). High gossypol was found in genotype 10 (Small leaf and medium ball size) (C-1622) low in genotype 3 (Thick, smooth and less hairy leaf) (Bar-12/13). High reducing sugar was found in genotype 2 (Semi and Small Okhra leaf) (Pentense Na-4 Chines) and low in genotype 9 (Stay green type) (C-1998). High tannin was found in genotype 5 (Monopodial and open plant type) (ISC-67-413) and low in genotype 3 (Thick, smooth and less hairy leaf) (Bar-12/13).
