| dc.description.abstract | Pearl millet [Pennisetum glaucum (L.) R. Br.] is highly cross-pollinated, diploid, photo-synthetically efficient C4 monocot plant belonging to family Poaceae. In present investigation, seventy three pearl millet inbred lines were evaluated for genetic variability in yield and its contributing traits, micronutrients (Fe and Zn) and crude protein content. Molecular diversity analysis was assessed using SSR primers. The analysis of variance indicated significant differences among all inbred lines for all the traits. A narrow difference was observed between PCV and GCV for all the traits suggesting the little role of environment in the expression of all these traits. A highly significant and positive correlation between grain Fe and Zn content was observed. Grain yield per plant showed no significant correlation with Fe, Zn and protein content suggesting improvement in nutrient value can be attempted without compromising on yield. Three inbred lines, H2302, HMP 808 and HBL 1121 were found to have high Fe, Zn and protein content as well as high yield. Inbred lines HMS 53B, HPT-2-12-59, H12/009, HMS 14B and H72-2-2 contained higher Fe and Zn than HBL 11, male progenitor of elite hybrids HHB 197, HHB 223, HHB 226, and thus may be used in developing superior hybrids. Out of 40 SSR primers used for screening, 19 were found to be polymorphic and used for molecular diversity assessment. A total of 46 alleles were amplified with 2.42 average allele per locus and 0.38 average PIC. At a similarity coefficient of 45%, seventy three inbred lines were grouped into two major clusters. HBL 0551 shared a very high genetic similarity with HBL 11 thus may be used as male parent in hybrid development programmes. | en_US |
