Informative markers identification and multivariate analysis of selected DxP for the purpose of QTL mapping

Abstract

Abstract.A study was carried out to generate a linkage map of oil palm dura x pisifera (DXP) population. A subset of sample from a DXP mapping family was screened using 325 SSR primers, of which 221 were informative. To date, 150 SSRs have been genotyped across the entire DxP population via capillary sequencer, where 73 SSRs had 1:1 segregation ratio, 64 had 1:1:1:1, 3 had 3:1 and ten had 1:2:1 segregation ratios. Kolmogorov-Smirnov tests by SPSS revealed that most of the bunch quality components had normal distribution which fulfilled one of the pre-requisites to carry out phenotype-genotype correlation association.
