The prospective of Peroxidase Isozyme biochemical marker, have been investigation in the present study, ten pearl millet hybrids [Pennisetum glaucum (L.) R. Br.] Genotypes were used to examine the suitability of peroxidase enzymes for characterization of pearl millet genotypes. Band number 1 (Rm = 0.120) was present in three hybrids i.e. GHB-526, GHB-538 and GHB-719. Band number 2 (0.158) was also present in three hybrids i.e. GHB-538, GHB-577 and GHB-719. Band number 3 (Rm = 0.380) was present in only one hybrid i.e. GHB-719 while band number 4 (Rm = 0.429) was present in five hybrids GHB-538, GHB-719, GHB-732, GHB-235 and GHB-757. All the seven bands were present in only one hybrid GHB-719. 9 DAG stage was found to be more effective as compared to 3 DAG and 6 DAG by showing more number of bands. Among the 10 genotypes studied, two could be differentiated from each other Total 13 bands of peroxidase isozymes were observed at 3, 6 and 9 day after germination (DAG). A total of 15 alleles were generated by isozymes at different DAG (3, 6 and 9 days) with an average of 5 bands per day. Banding pattern at 6 DAG showed that band number1, 2 and 3 (Rm = 0.525, 0.573 and 0.600) were present in all the hybrids except for GHB-744, in band number 1. At 9 DAG seven bands of peroxidase isozymes were observed having Rm value of 0.120, 0.158, 0.380, 0.429, 0.430, 0.478, and 0.760.

Abstract


The prospective of Peroxidase Isozyme biochemical marker, have been investigation in the present study, ten pearl millet hybrids [Pennisetum glaucum (L.) R. Br.] Genotypes were used to examine the suitability of peroxidase enzymes for characterization of pearl millet genotypes. Band number 1 (Rm = 0.120) was present in three hybrids i.e. GHB-526, GHB-538 and GHB-719. Band number 2 (0.158) was also present in three hybrids i.e. GHB-538, GHB-577 and GHB-719. Band number 3 (Rm = 0.380) was present in only one hybrid i.e. GHB-719 while band number 4 (Rm = 0.429) was present in five hybrids GHB-538, GHB-719, GHB-732, GHB-235 and GHB-757. All the seven bands were present in only one hybrid GHB-719. 9 DAG stage was found to be more effective as compared to 3 DAG and 6 DAG by showing more number of bands. Among the 10 genotypes studied, two could be differentiated from each other Total 13 bands of peroxidase isozymes were observed at 3, 6 and 9 day after germination (DAG). A total of 15 alleles were generated by isozymes at different DAG (3, 6 and 9 days) with an average of 5 bands per day. Banding pattern at 6 DAG showed that band number1, 2 and 3 (Rm = 0.525, 0.573 and 0.600) were present in all the hybrids except for GHB-744, in band number 1. At 9 DAG seven bands of peroxidase isozymes were observed having Rm value of 0.120, 0.158, 0.380, 0.429, 0.430, 0.478, and 0.760.
