Genetic variability and heritability estimation in Amaranthus (Amaranthus spp.) genotypes

Author(s): Yogendra Kumar, Rameshwar Prasad, Chameli

The experiment was conducted at Horticulture Research cum Instructional Farm, Department of Horticulture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) during rabi 2014-15. Twenty five genotypes of Amaranthus were evaluated and observations were recorded on leaf yield and its attributes on five randomly selected competitive plants from each plot and replication. The analysis of variance indicated the existence of sufficient amount of variability among genotypes for all the characters studied except for test weight and stem girth. The phenotypic variance was in general higher than the genotypic variance for all the characters. Among different yield attributing characters studied, seed yield (gm) plot-1 had the highest magnitude of PCV (39.89   per cent) and GCV (38.83 per cent).
