Variability in total phenolic content of pearl millet genotypes
inbreds and designated B-lines
Keywords:
Pearl millet, variability, total phenolic, inbred linesAbstract
Total phenols of the 90 pearl millet genotypes comprising 46 each of inbreds and designated B-lines (maintainer of CMS lines) grown during kharif-2013 was estimated and those of the 27 genotypes (9 inbreds and 18 designated B-lines) selected during kharif-2013 further grown during kharif-2014 and estimated total phenolic content. Across the groups, pearl millet genotypes showed a significant and marked variation during both the seasons. It varied from rom 175 to 435 mg catechol equi./100g during kharif-2013 and from 191 to 387 mg catechol equi./100g dring kharif 2014. The mean total phenolic content of two seasons (kharif-2013 and kharif-2014) of selected lines varied from 199 to 400 mg catechol equi./100g. During both the seasons designated B lines showed lower mean total phenolic content than that of inbred lines. On the basis of mean performance during kharif-2013 and kharif-2014 HTP 94/54, LPBL 10/112, HMS 14B and HMS 21B were identified as low total phenols containing lines whereas, DPHBL-11-123, HBL 112/H12/1011, HMS 36B and HMS 53B were identified as high phenolic containing pearl millet lines.
