Genotyping and phenotyping of pearl millet [Pennisetum glaucum (L.)R.Br.] hybrids and their parental lines
(CCSHAU, 2017) Suman; Chhabra, A.K.
Present study was carried out to characterize pearlmillet hybrids and their parental lines and resemblance between hybrids and their parents. Phenotypic and genotypic diversity in pearl millet [Pennisetum glaucum (L.) R. Br.] was studied using 28 morpho-agronomic traits (15 qualitative and 13 quantitative) and 47 SSR markers. Significant mean sum of squares indicated sufficient variation in the lines. Correlation coefficient analysis during 2011-12 revealed that leaf sheath length, leaf blade length, leaf blade width, number of nodes/ plant, spike length, spike girth, number of productive tillers/ plant, plant height, 1000 seed weight, fresh fodder weight, dry fodder weight have positive and significant correlation with grain yield and during 2012-13, leaf sheath length, leaf blade length, number of nodes/ plant, spike girth, plant height, 1000 seed weight, fresh fodder weight and dry fodder weight have positive and significant correlation with grain yield. Resemblance between hybrids and their parents was higher at molecular level than morphological level. Genotyping with 14 polymorphic markers revealed that Xipcs is highly informative primer as it had highest PIC value (0.49) followed by Xpsmp 2089 (0.48).
