However, its production comes with specific challenges. In addition, effective post-harvest management is critical to ensure the quality and availability of shallot bulbs for extended periods. This study assessed the yield performance and storability relevant traits of five shallot cultivars (Saboula Jaba, Espagne Jaba, Daou Jaba, Tata Jaba, and N’galamandjan Jaba) under controlled storage conditions. Field experiments were conducted in 2021 to evaluate growth and yield in terms of bulb quantity, size, and weight. Storability traits such as firmness, weight loss, and Total Soluble Solids (TSS) were also measured for each entry. The five ecotypes of shallots were evaluated on-station with a total rainfall of 810 mm in 2021. The results revealed statistically significant variations (p > 0.01) in storability traits and yield among the tested entries. Furthermore, the weight loss of stored bulbs varied, indicating genetic differences among the cultivars that can influence their moisture retention abilities, leading to differences in weight loss rates. Indeed, Daou jaba showed less weight loss and superior firmness. The top highest-ranking entry for yield was shown by N’galamandjan jaba with 40 T/ha, followed by Saboula jaba with 39 T/ha. These highest productivity entries also showed significantly higher bulb quantity and individual bulb size. While there was a significant correlation between weight loss and firmness, a correlation between weight loss and TSS was also observed. The weight loss and firmness of N’galamandjan jaba were significantly correlated (r = 0.52) on the one hand, and on the other hand, the weight loss and visual quality of Espagne Jaba were highly and significantly correlated (r = 0.69). N’galamandjan Jaba and Saboula Jaba can be used to improve the yield and the storability relevant traits and prevent post-harvest losses.展开更多

Sixty-four accessions, characterized under Samanko conditions, were assessed using a phenotypic evaluation system. Observations and biometric measurements covered 34 variables, revealing considerable agro-morphological variability among the accessions, particularly in qualitative traits. Significant differences were observed at the 5% threshold between accessions for variables such as plant height, plant diameter, pod width, and 50% flowering date. Several positive correlations were also noted between the traits. The study identified three distinct groups of accessions based on diversity structuring. The first group mainly comprised accessions with a short growth cycle and average yield. The second group was characterized by accessions with superior agronomic performance, featuring a long cycle and high yields. In contrast, class III exhibited lower agronomic performance compared to the other two classes. The variability identified in this study offers potential for use in Cleome gynandra L. improvement programs in Mali, with class II accessions distinguished by their dark green, hairy stems and superior agronomic performance being the most promising candidates for improvement.展开更多

This review aims to assess the genetic diversity within the collection to understand the range of genetic variation. Thirty-two agromorphological parameters of Ten amaranth accessions were analyzed in Samanko conditions. Wide variability was present concerning leaf pigmentation (PigF), flower density index (IDF), seed color (CH), and Branching index (IR). Statistical analysis showed significant differences among accessions for morphological characters such as number of plants, leaf width, stem height, terminal inflorescence length of stem, axillary inflorescence length, 50% flowering and 1000 grain weight. It appears that the Axillary Inflorescence (LIA) and the Length of the Terminal Inflorescence are correlated (r = 0.82). Length of the inflorescence terminal of the stem (LITT) and the Length of the Terminal Basal Branches (LITBT) are associated (r = 0.75). Stem height presents a robust correlation (r = 0.447) with 50% flowering date. The length of the inflorescence Axillary was also highly correlated with the length of the inflorescence terminal of the stem (r = 0.904*). Ascending hierarchical classification revealed three distinct classes: C1: Madira 1, Madira 2, A2004, A2002;C2: TP5-sel, N’gourouma, Akeri, AC-NL;C3: AHTI, Akeri. “Akeri.” “TP5-sel,” and “N’gourouma” are associated with the weight of 1000 grains, the length of the terminal branches, and the shape of the terminal inflorescence. “Poly” and “AHTI” are quite similar and are associated with the parameters of the length of basal branches and length of a terminal inflorescence of the stem “Madira 1”;“Madira 2”, “A2004”, “A2002” on the correlation circle indicates that the height of the plants and the 50% flowering date. These results indicate a high possibility of genetic diversity among the amaranth accessions within the collection. The data can be exploited in future breeding programs to improve the species.展开更多
