Its production is hampered by both biotic and abiotic stress. Early-maturing genetic resources appear as an excellent choice to manage adverse climatic change’s effects. This study aimed to find the best extra-early maize genotypes based on genotype by environment interactions in the groundnut agro-ecological zone of Senegal. The trials were conducted in Paoskoto, Ndiedieng, Nioro and Keur Sene during the rainy seasons of 2016 and 2017. Six extra-early maize genotypes were evaluated following a randomized complete block design with three replications. Data on grain yield were recorded and analysed using additive main effect and multiplicative interaction and genotype plus genotype by environment biplot methods. Analysis of variance revealed a significant (P < 0.01) genotype by environment effect on grain yield. The sum of squares variation was higher (77.2%) explained by the environment effect. The genotype 2008-TZEE-W-STR showed the highest yield performance (3299 kg ha-1) and lowest yield stability index (3). This genotype can be suggested to farmers for its cultivation and a good candidate for early maturing maize breeding program in Senegal.

Thiès, Diourbel, Fatick Index. décimale : H280-Maladie des plantes Résumé : Pearl millet is a dominant staple cereal crop for smallholder farmers in Senegal. However, the crop is constrained by various nonbiotic and biotic stresses such as downy mildew disease. To assess the prevalence of this disease in Senegal, a field survey was conducted during the rainy season of 2017 across eight main pearl millet production regions following latitudinal gradient with different climatic conditions. Results showed that downy mildew prevalence was higher in Kaolack (incidence = 68.19%), Kaffrine (incidence = 77.19%), Tambacounda (incidence = 97.03%), Sedhiou (incidence = 82.78%), and Kolda (incidence = 98.01%) than Thies (incidence = 28.21%), Diourbel (incidence = 24.46%), and Fatick (incidence = 37.75%) regions. The field survey revealed an incidence as high as 98% and 28% of infected area in surveyed fields. Significant correlations between geographic coordinates, disease incidence, and infected areas were also observed. This study provided information that could help to understand the prevalence of downy mildew in pearl millet in Senegal. En ligne : https://www.hindawi.com/journals/tswj/2019/1252653/ Exemplaires

Généralités Résumé : Peanut aflatoxin contamination caused by Aspergillus flavus is a serious constraint for food safety and human health in Senegal. *e present study aimed to identify sources of resistance for A. flavus colonization and aflatoxin contamination. *us, seeds from 67 peanut genotypes were tested under laboratory conditions. Aqueous conidial suspension of an aflatoxinogenic strain of A. flavus was used for inoculation in Petri dishes containing ten seeds of each genotype, and data on incidence and severity were recorded. Total aflatoxin concentration in seeds was determined on 15th day after inoculation using mReader® method. Results showed a significant (p < 0.001) variation of aflatoxin, incidence and severity among the tested peanut genotypes. Incidence ranged from 0 to 70% with a mean of 20.36 ± 0.8%. Out of the 67 genotypes, eight showed incidence less than 10%. Severity ranged from 0 to 44% with a mean value of 8.82 ± 0.45%.*e genotype 12CS_104 showed aflatoxin concentration level in conformity with the European standard (4 ppb). Out of three clusters revealed by hierarchical classification based on disease incidence and severity, the cluster 1 contained 33 genotypes characterised by low incidence and severity values. *ese genotypes can be tested under field conditions to confirm their resistance to A flavus.

Catégories : SCIENCES ET PRODUCTIONS VEGETALES Mots-clés : Petit mil, Moisissure, Génotypage, Résistance, Incidence, Sénégal Index. décimale : F028-Génétique et amélioration des plantes Résumé : Sclerospora graminicola is a pathogen that causes important damage in pearl millet [Pennisetum glaucum (L.) R. Brown] fields in Asia and Africa. In order to identify new sources of resistance to this disease, a set of 20 genotypes was assessed during the rainy season 2015 at Bambey, Nioro, Kolda and Sinthiou Maleme research stations in Senegal. Comparative survey between locations showed that the highest downy mildew incidence (100%) was recorded in Kolda. The 7042S, an international susceptible check, showed downy mildew incidence of 91.12%, IP22441 line was susceptible at Kolda (incidence = 30.5%), resistant at Sinthiou Maleme (incidence = 6.5%), moderately resistant at Bambey (incidence = 18%) and highly susceptible at Nioro (incidence = 70%). IP22295 line was susceptible at Kolda (incidence = 24.5%) but resistant at Bambey (incidence = 0%), Nioro (incidence = 3.5%) and Sinthiou Maleme (incidence = 0%). A hierarchical cluster analysis of these tested genotypes integrating agronomic parameters and response to downy mildew has identified four genotype groups characterized by downy mildew resistance, vegetative growth, panicle yield and flowering time. This study has shown the variability of S. graminicola populations from different tested locations. Genotypes IP22315, IP2295, SOSAT-C88-Sadore and SOSAT-C88-Pantacheru presented stable resistance to downy mildew across the tested locations. These genotypes can be used as parents for breeding pearl millet varieties resistant to the downy mildew disease under Senegal environments. Exemplaires

Catégories : SCIENCES ET PRODUCTIONS VEGETALES Mots-clés : Mil Index. décimale : F300-Génétique et amélioration des plantes Résumé : Downy mildew of pearl millet induced by Sclerospora graminicola is a major disease that causes significant yield losses in most pearl millet production areas worldwide. The pathogenic variability of S. graminicola populations from four agro-ecological zones in Senegal was assessed under field conditions. A set of 19 pearl millet lines, including 12 downy mildew-resistant differential lines with five improved cultivars and two local checks was evaluated during two consecutive rainy seasons (2015 and 2016) at Bambey, Nioro, Kolda and Sinthiou, representing the main pearl millet-growing zones of Senegal. Significant differences were observed among the tested lines, pathogen origin, year and their interactions for resistance to S. graminicola. Except for ICMR 356 and 7042 S, the downy mildew-resistant differential lines differed in their resistance to the pathogen from
the four agro-ecological zones over the years, providing evidence that the S. graminicola isolates represented different races of the pathogen. Among the locations where the experiments were established, the highest average of downy mildew incidence over the two years was recorded at Nioro (18.7 ± 2.6%), Kolda (17.6 ± 1.8%) and Bambey (12.1 ± 2.3%), while the mean downy mildew incidence was lowest at Sinthiou (6.9 ± 2.9%). This finding indicated that populations of pathogen from Kolda, Nioro and Bambey are more virulent compared to the one from Sinthiou.Exemplaires
