Besides these morphological and agronomical differences, both rice varieties show distinct physiological and biochemical features.
Kızıl (2006) reported morphological and agronomical characteristics of some wild and cultivated Isatis species.
Particularly, they were chosen according to their morphological and agronomical characteristics regarding phenotypic behaviour against fungal pathogens, abiotic stress, seed number per capitulum and high oil yield.
Figure 2a shows the distribution of each accession into the two populations (identified by the Structure software, and designated as group I and group II, hereafter) and the three clusters (according to morphological and agronomical data as classified by Vaz Patto et al. [ 6]).
To detect intervarietal polymorphisms, a preliminary screening of the intergenic spacer trnS-GCU - trnG-UCC, previously demonstrated to be polymorphic among olive varieties [ 40], was performed on a set of 30 cultivars having different geographical distributions and representing a wide range of morphological and agronomical phenotypes (data not shown).
More than 20 genetic linkage maps have been generated in B. rapa, some of which have been applied to quantitative trait locus (QTL) analysis of morphological traits, and agronomical traits including fatty acid content, glucosinolate accumulation, phytate and phosphate concentrations, and disease resistance.
Each of these modelling spatial units was characterised on agronomical, morphological and contextual variables selected from in-depth spatially explicit farm surveys.
To find the key determinants to the inferred structure of these two groups, we investigated the geographical proximity, as well as the morphological, agronomical and ecological characteristics in the accessions belonging to each group.
As in the case of Bayesian clustering, no clear associations between the groups retrieved from DAPC and morphological, phenological or agronomical traits were found (e.g., branching pattern, days to flowering, disease resistance profile, oil content).
As yet, there is no clear evidence that such a scenario of gene discovery can be extended to traits with agricultural importance, such as yield performance, environmental stress tolerance and other morphological characteristics of agronomical interest.
