dc.description.abstractGenetic divergence using Mahatanobis D2 technique was studied in nine F1 families of West Coast Tall x Dwarf green coconut hybrids for 13 vegetative characters and yield components. Bulk F1 populations of the same cross as well as open pollinated progenies of West Coast .Tall were also studied. Individual cross combinations differed significantly for all the characters studied and could be grouped into four clusters depending on similarities of their D2 values. Setting percentages female flower production, length of leaf, number of leaf scars/metre, number of functioning leaves and height contributed maximum towards the total divergence. The pattern of clustering indicated that phenotypic uniformity can involve considerable genetic diversity. It was suggested that proper choice of palms even among tall and dwarf varieties of coconut may be done for the efficient exploitation of these hybrids. The polygenic nature of the character of dwarfness in coconut has been discussed and the genetic status of the offtype segregants in the dwarf explained.en_US
