Ik. Dawson et al., DETECTION AND ANALYSIS OF GENETIC-VARIATION IN HORDEUM-SPONTANEUM POPULATIONS FROM ISRAEL USING RAPD MARKERS, Molecular ecology, 2(3), 1993, pp. 151-159
Randomly amplified polymorphic DNA (RAPD) markers were used to analyse
genetic diversity within and between Hordeum spontaneum populations s
ampled from Israel. Nei's index of genetic differentiation was used to
partition diversity into within and between population components. Fi
fty-seven per cent of the variation detected was partitioned within 10
H. spontaneum populations. Using principal component and multiple reg
ression analysis, part of the variation detected between populations w
as seen to be associated with certain ecogeographical factors. Fifty-e
ight per cent of the distribution of the phenotypic frequencies of thr
ee RAPD phenotypes detected using a single primer in 20 H. spontaneum
populations could be accounted for by four ecogeographical variables,
suggesting adaptive variation at certain RAPD loci.
