Heritabilities of certain yield characters of the coconut palm

Journal of Genetics Aims and scope Submit manuscript

Summary

Heritability values for the flowering-period, yield of nuts, yield of copra and weight per husked-nut of the coconut palm, have been estimated. Genetic correlations between these four characters have been ascertained. The heritability values for yield of copra and weight per husked-nut are high, for yield of nuts intermediate, and for the flowering-period low. The genetic correlation between yield of nuts and copra is high and positive, correlation between yield of copra and flowering-period is high and negative. Genetic progress in the progenies is likely to be more, if the seed parent is selected on high yield of copra and of nuts rather than on weight per husked-nut and flowering-period.
