Genetic Studies in Some Oil Palm Breeding Populations in Malaysia
Five oil palm breeding populations were studied for heritability, phenotypic correlations, path coefficient analysis and yield performances involving oil yield, number of bunches, single bunch weight, percentage fruit-to-bunch, percentage mesocarpto- fruit and percent age oil-to-wet me socarp. T...

| 总结: | Five oil palm breeding populations were
studied for heritability, phenotypic correlations,
path coefficient analysis and yield performances
involving oil yield, number of bunches, single bunch
weight, percentage fruit-to-bunch, percentage mesocarpto- fruit and percent age oil-to-wet me socarp. The
breeding populations consisted of different families
of Deli Duras, Teneras and Pisiferas grown at Banting
between 1968 and 1970.
Two methods, namely, parent offspring
regression and combined (genotype x year) analyses
were used to estimate heritabilities. Heritabilities
using combined analysis were larger than those
estimated using parent offspring regression. However,
both methods showed that heritabilities for total
bunch weight were lower than those of its component
characters.
The correlation studies for oil yield and
its components showed wide variation in association
in both magnitude and direction. Nevertheless,
number of bunches and single bunch weight negatively
and significantly correlated in four of the five
populations studied. |
