| contents | Evaluation of carrot (Daucus carota L.) hybrids at mid-elevation and higher in the Nilgiris V.P. Santhi P.A. Priya Agrociencias hybrids heritability genetic advance Genetic variability Investigations were made on yield and quality in six hybrids of carrot spanning two seasons under Nilgiri hill conditions during the year 2012-2013. The hybrids were evaluated for per se performance, genotypic coefficient of variance, heritability and genetic advance. A high estimate for genotypic coefficient of variation was observed in root-splitting percentage, total chlorophyll, root carotenoids, leaf carotenoids and root-forking percentage in the hybrids, indicating a potential for improvement of these traits by simple selection, in kharif and summer. Leaf and root carotenoid content, total chlorophyll, number of leaves and root weight exhibited higher values for heritability, coupled with a high genetic advance, revealing these traits to be under the control of gene action. Simple selection can, therefore, effect improvement in these characters. 2016 artículo científico 0973-354X https://www.redalyc.org/articulo.oa?id=577077088015 en http://www.redalyc.org/revista.oa?id=5770 Journal of Horticultural Sciences application/pdf Society for Promotion of Horticulture Journal of Horticultural Sciences (India) Num.1 Vol.11 |
