Abstract
Aim:
The present study was conducted to evaluate oil palm dura progenies developed
from Zambia and Cameroon germplasm sources for bunch components for the
selecting of high oil yielding mother palms.
Methodology: Total 77 dura genotypes were evaluated by
considering 15 different bunch components. Bunch analysis data were collected
from tenth year onwards after planting. The genetic diversity, Principal
component analysis, correlation and path analysis of the genotypes were
estimated.
Results:
Study revealed that oil-to bunch ratio depends on fruit-to-bunch ratio and
mesocarp-fruit ratio. The ANOVA value showed a significant variability among
the genotypes for most of the bunch traits and the identified genotype P35
(24.53 %) was highest oil yielder. Positive significant correlation (p≤ 0.01)
of mesocarp-to-fruit ratio and oil-to-dry mesocarp with oil-to-bunch ratio were
noted in this study. Based on path analysis, the information obtained from
this study is the oil-to-wet mesocarp ratio (0.697) showed the highest
significant positive direct effect on oil-to-bunch ratio followed by
mesocarp-to-fruit ratio (0.570).
Interpretation: This study may support for the future
selection of mother palms to utilize in oil palm improvement programmes.
Introgression into existing breeding materials and breeding for seed production
