SNP Markers and Economics of Marker-Aided Breeding
SNP
5452 EST sequences mined
In silico
analysis of SNPs and
indels in sequences
1180 SNP sites and 137 indel polymorphism were found;
mesocarp had high frequency of 2.91 SNPs and indels
per 100 bp.
[68]
24 SNP-based CAPS markers;
6 markers were informative
380,000 oil palm genomic
sequences mined and 20,000
good-quality oil palm SNPs
identified; restriction enzyme
sites were identified.
317 samples from 11 African and 3 South and Central
American countries

Genome-wide selection
Price '03
Economics of MARS (marker-
assisted reciprocal recurrent
selection)
Cost per unit gain was 26-57%
lower with genome-wide
selection than with phenotypic
selection when markers cost
US$1.50 per data point (SSR
markers), and 35-65% lower
when markers cost $0.15
per data point (SNP, DArT
markers).
Genome-wide selection saved time and money in oil palm.
With population sizes of
N
50 or 70, time per unit
gain was 11-23 years with genome-wide selection and
14-25 years with
N
50 in oil palm; genome-wide
selection is superior to MARS and phenotypic selection
in terms of gain per unit cost and time.
