Genetic variability and correlation analysis of vegetative, floral, nut and yield characters
were studied with 11 tall and 3 dwarfs which include 6 indigenous and 8 exotic coconut
genotypes from diverse geographic origin. Analysis revealed a high degree of variability
for most of the character studied. The variability studies among fourteen genotypes for
different traits revealed that number of nuts per palm, dehusked nut weight, whole nut
weight, plant height, stem girth, petiole length, shell thickness, number of female flowers
and number of nuts per bunch recorded high values for phenotypic coefficient of variation
and genotypic coefficient of variation. Heritability estimates for all the characters studied
were grouped as high. Genetic advance expressed on per cent mean was high for whole nut
weight, dehusked nut weight, petiole length, number of nuts per bunch, number of female
flowers per palm, number of nuts per palm. Correlation studies with nut yield per palm
showed a positive and significant association with number of female flowers /palm/year,
number of nuts/bunch, whole nut weight, husk thickness, kernel thickness, shell thickness,
husk weight, copra content. Oil content exhibited positive and significant association with
kernel weight and copra weight. This genetic analysis indicates the use of these characters
in selection for coconut improvement. Thus, these characters are to be given importance
for nut yield improvement in coconut.
