Thirty accessions of Lagenaria siceraria from the Nangui Abrogoua University germplasm collection were analyzed using three microsatellite markers. The average Polymorphism Information Content (PIC) value was 0.61. The average observed heterozygosity value (H0 = 0.631) compared to the average expected heterozygosity value (He = 0.645) did not show significant differences in the selected accessions, which suggested random mating in the set of accessions. Within accession inbreeding estimate (FIS), was 40% and was not significantly different from zero. The reduction of heterozygotes was likely the result of presence of null alleles. Analysis of Molecular Variance (AMOVA) within and among 30 accessions of L. siceraria revealed that 39% of the total variation resides among accessions and 61% within accessions. Accession structuring pattern derived from Bayesian clustering analysis revealed two clusters. Based on the genetic structure of the accessions analyzed, a sampling strategy to collect and conserve genetic resources of L. siceraria was suggested.

In order to characterize neglected and underutilized legumes seeds (NULs), prospection, collection and characterization were carried out in five administrative regions from Cote d’Ivoire. Two thousand and fifty-four accessions were collected. NULs cultivation is done mainly by women (88.1% compared to 11.9% of men). Productors distinguish 22 morphotypes of NULs based on seeds shapes, colors and patterns. Morphological traits of the collected morphotypes revealed a significant phenotypic polymorphism. Quantitative analyses showed a clear structure of accessions;three main groups were revealed. The first group contains accessions with large and thick seeds, but a low index shape opposite to group II with high index shape. Seeds of group III are characterized by small width and thickness, but a high shape index. Analyses of qualitative traits revealed five groups characterized by heterogeneous or homogeneous coloured integument, inked or elevated edge of hilum, presence or absence of eye.

Cassava is the second most important food crop produced and consumed in Côte d’Ivoire, after yam. White-fleshed varieties, which are low in total carotenoids, are widespread, while coloured-fleshed varieties (yellow to orange), carotenoid-rich, are rare. However, the consumption of carotenoid-rich cassava varieties could help to alleviate health problems related to vitamin A deficiency. This study aims to identify high agronomic performance, carotenoid-rich and versatile cassava varieties among 31 clones introduced from IITA. They were compared to three controls, Bocou2, Yacé and Bonou2, according to agronomic and technological parameters. Results found that out of the 31 clones, six (I082425, I084157, I084563, I085894, I083774 and I070520) were more productive than the control Bocou2 (46.01 ± 14.88 t·ha-1);the clone I083774 had the highest yield (55.88 ± 6.16 t·ha-1). Twenty-one clones had dry matter contents, ranging from 37% to 41%, significantly similar to Yacé control (42.70%). Thirteen clones had highest total carotenoid contents than the control Bocou2. Clones I084157 and I082425 recorded the highest total carotenoid contents with 17.57 ± 1.92 and 18.39 ± 1.19 μg·g-1 respectively. Overall 31 tested clones were fibrous to varying degrees while 27 clones had mild or neutral post-cooking flavours and 17 clones had poor cooking. The clone I084157 is the best compromise of agronomic and technological desired traits.

In C?te d’Ivoire, ginger (Zingiber officinale Rosc.), generally used to make a drink called “Gnamankoudji”, has become an important source of agricultural income diversification. In order to assess the agromorphological diversity of a ginger collection from different regions of C?te d’Ivoire, a survey collection of accessions was carried out in the different production zones of the country. One hundred and eighty-eight ginger accessions were collected in 15 regions and one autonomous district of C?te d’Ivoire. Analysis of variance revealed that all the variables used in this study discriminated between the ginger accessions collected. Principal component analysis revealed morphological variability of 45.931% for the first two components. Ascending Hierarchical Classification was used to classify these accessions into three groups based on fourteen quantitative characters. These three groups were formed independently of collection areas and are characterized by moderate morphological variability. This variability has been structured into three distinct agromorphological groups, with thallus (rhizome) length and width, finger width, secondary finger length and yield in tons per hectare as distinctive characters. This revealed genetic diversity could be exploited in ginger breeding and improvement programs in C?te d’Ivoire.

Restoration of cytoplasmic male sterility (CMS) in sunflower was demonstrated to be controlled by polygenes by analysing 982 effective crosses among 109 self-crossed lines and 16 CMS lines. Two self-crossed lines and one CMS line with distinct genotypes were applied to creation of segregating populations for dNA bulks of the target gene Rfl. Bulked dNA was prepared in order to investigate single gene Rfl and its gene marker among polygenic characters at the same genetic background. Using 80 10-mer operon primers, 620 RAPd reactions were carried out between fertile and sterile dNA bulks. In about 800 loci, primary results showed that 8 were related to the restoration genes. Furthermore. 2 were confirmed as RAPd markers for gene Rfl by examining 9 maintenance and 7 restoration lines. This method is the improvement for bulked segregant analysis[1] with which markers of single gene of target can be identified rapidly among polygenic characters.
