Title:

Effect of provenance and progeny selection in Calamus andamanicus Kurz for fast growth

Authors:Indira, E.P; Renuka, C

Abstract:Calamus andamanicus is a large diameter cane preferred for furniture frame work. This species was found to be promising in a species trial conducted in Kerala, India. Hence, a provenancecum- progeny trial was carried out to select the best provenance or family for fast growth and other desirable characters. Eight families belonging to four provenances of the Andaman and Nicobar Islands were tested for superiority with respect to growth in an evergreen forest area with 3000 mm rainfall at 300 m asl. Analysis of growth data in nursery and field revealed no significant difference between provenances. However, the difference between families was highly significant. The phenotypic and genotypic coefficients of variation were high for basal diameter, whereas they were low for height. The family heritability was found to be high and single tree heritability to be moderate which indicate the influence of additive as well as non-additive genes on growth characters. Hence, family selection will be desirable for enhancing productivity rather than provenance selection.
