“…It occurs because gene flow between populations is high (Nm=8.2008) due to the seed dispersal. According to Zongo et al (2005) and Muraya et al (2013), farmers can bring sorghum from one place to another and exchange seeds with nearby areas, so people movement may cause gene flow among populations. The presence of similar accessions in different populations support that gene flow is present between populations located on different island.…”

Sorghum has great potential to be developed in marginal lands of Indonesia including East Nusa Tenggara. However, the information about sorghum diversity in this area was very limited. This research aimed to describe morphological variation, and assessing the value of genetic diversity based on morphological characters of local sorghum cultivar of East Nusa Tenggara. The exploration and sample collection were conducted in 3 islands, i.e.: Timor, Sumba, and Flores. The observation of morphological characters was based on sorghum descriptor. Morphological character similarities were analyzed using Simple Matching (SM) coefficient, and a dendrogram was constructed using Unweighted Pair Group Method with Arithmetic Average (UPGMA) method. The results showed that 36 accessions of sorghum in East Nusa Tenggara varied in 17 morphological characters. At the similarity coefficients of 48%, all sorghum accessions were separated into 2 groups based on the presence or absence of aleurone layer. Group I consisted of 12 accessions with no aleurone layer, while group II consisted of 24 accessions has aleurone layer. The genetic diversity of sorghum of East Nusa Tenggara is low (I=0.62-0.71 and h=0.37-0.42). The genetic diversity between populations (H T =0.4203) is higher than within populations (H S =0.3961). This study provides the first complete information about sorghum diversity in East Nusa Tenggara that will be useful as basic information for sorghum development in this area in the future.

“…Environmental adaptation is mostly observed through quantitative variation, affecting very few qualitative traits such as panicle compactness and shape [53,57,58]. By contrast, biochemical and genetic diversity is found essentially at the local level, and even at the field level [30,[50][51][52]55,[57][58][59][60]; its organization shows no environmental component, even when the geographic range of the studies include sharp altitudinal or precipitation gradients [29,48,61].…”

A better knowledge of factors organizing crop genetic diversity in situ increases the efficiency of diversity analyses and conservation strategies, and requires collaboration between social and biological disciplines. Four areas of anthropology may contribute to our understanding of the impact of social factors on crop diversity: ethnobotany, cultural, cognitive and social anthropology. So far, most collaborative studies have been based on ethnobotanical methods, focusing on farmers’ individual motivations and actions, and overlooking the effects of farmer’s social organization per se. After reviewing common shortcomings in studies on sorghum and maize, this article analyzes how social anthropology, through the analysis of intermarriage, residence and seed inheritance practices, can contribute to studies on crop genetic diversity in situ. Crop varieties are thus considered social objects and socially based sampling strategies can be developed. Such an approach is justified because seed exchange is built upon trust and as such seed systems are embedded in a pre-existing social structure and centripetally oriented as a function of farmers’ social identity. The strong analogy between farmers’ cultural differentiation and crop genetic differentiation, both submitted to the same vertical transmission processes, allows proposing a common methodological framework for social anthropology and crop population genetics, where the classical interaction between genetic and environmental factors, G × E, is replaced by a three-way interaction G × E × S, where “S” stands for the social differentiation factors

“…breeders have been using morphological per se performance (Barro-Kondombo et al, 2008;Sawadogo et al, 2014) and genetic relationship (Zongo et al, 2005;Deu et al, 2006;Sagnard et al, 2011;Billot et al, 2013) method to classify available germplasm into distinct heterotic groups and to identify suitable parents for crosses. However, several methods using combining ability information for heterotic grouping, reported in maize, showed the usefulness of such methods in identifying suitable hybrid parents (Fan et al, 2009;BaduApraku et al, 2013;Akinwale et al, 2014).…”
