Abstract Rice production faces the challenge to be enhanced by 50% year 2030 meet growth of population in rice-eating countries. Whereas yield cereal crops tend reach plateaus and a is likely deeply affected climate instability resource scarcity coming decades, building rice cultivars harboring root systems that can maintain performance capturing water nutrient resources unevenly distributed major breeding target. Taking advantage gathering community biologists Global Science Partnership...
Sorghum is the fifth most important cereal crop world-wide and feeds millions of people in Sahel. However, it often faces early-stage water deficit due to false onsets rainy seasons resulting production decrease. Therefore, developing early drought tolerant material becomes a necessity but requires good knowledge adaptation mechanisms, which remains be elucidated. The present study aimed at assessing effects stress on ten elite sorghum varieties tested over two years (2018–2019) National...
Pearl millet plays a major role in food security arid and semi-arid areas of Africa India. However, it lags behind the other cereal crops terms genetic improvement. The recent sequencing its genome opens way to use modern genomic tools for breeding. Our study aimed at identifying components involved early drought stress tolerance as first step toward development improved pearl varieties or hybrids. A panel 188 inbred lines from West was phenotyped under well-irrigated conditions. We found...
Pearl millet (Pennisetum glaucum) thrives in arid and nutrient-poor environments, establishing its role as a crucial cereal crop for food security sub-Saharan Africa. Despite remarkable adaptability, yields remain below genetic potential, primarily due to limited water nutrient availability. In this study, we conducted ionomic profiling genome-wide association studies (GWAS) field conditions across two growing seasons unravel the basis of acquisition pearl millet. Soil ion content analyses...
Pearl millet is able to withstand dry and hot conditions plays an important role for food security in arid semi-arid areas of Africa India. However, low soil fertility drought constrain pearl yield. One target address these constraints through agricultural practices or breeding root system architecture. In this study, order easily phenotype the field conditions, we developed a model predict length density (RLD) plants from intersection densities (RID) counted on trench profile conditions. We...
Seedling root traits impact plant establishment under challenging environments. Pearl millet is one of the most heat and drought tolerant cereal crops that provides a vital food source across sub-Saharan Sahel region. millet’s early system features single fast-growing primary which we hypothesize an adaptation to Sahelian climate. Using crop modeling, demonstrate stress important constraint in agrosystems where pearl was domesticated. Furthermore, show increased growth correlated with water...
Abstract Local landrace and breeding germplasm is a useful source of genetic diversity for regional global crop improvement initiatives. Sorghum ( bicolor L. Moench) in western Africa (WA) has diversified across mosaic cultures end uses along steep precipitation photoperiod gradients. To facilitate utilization, West African sorghum association panel (WASAP) 756 accessions from national programs Niger, Mali, Senegal, Togo was assembled characterized. Genotyping‐by‐sequencing (GBS) used to...
Pearl millet is a key food security grain crop in the world's drylands due to its tolerance abiotic stresses. However, yield remains low and negatively impacted by climate change. Root phenes are potential targets improve productivity resilience environmental stress. sheer number of combinations resulting from interactions multiple challenge for empirical research. In silico approaches plausible alternative assess utility different phene varying states over diverse contexts. Here, we...

Drought is a major constraint on plant productivity globally. Sorghum [Sorghum bicolor (L.) Moench] landraces have evolved in drought-prone regions, but the genetics of their adaptation poorly understood. Here we sought to identify novel drought-tolerance loci and test hypotheses role known including those underlying stay-green (Stg) postflowering drought tolerance. We phenotyped 590 diverse sorghum accessions from West Africa 10 environments, under field-based managed stress [preflowering...

The root length density (RLD) distribution in the soil is a key factor for water and nutrient uptake but its direct assessment not easy. A field method presented here to assess RLD of sorghum (Sorghum bicolor L. Moench) from intersection (RID) taking orientations into account. was developed with four varieties cropped 2006 Bambey (Senegal) on sandy soil, validated basis independent data obtained two other 2008 Thiès Senegal loam soil. Sets 1 × 10-3 m3 cubic undisturbed samples were collected...
Heterotic grouping based on combining ability for traits of interest, in addition to plant performance and genetic relationship among germplasm, would be useful planning crosses breeding programmes. This study aimed at determining the abilities selected landraces morphological physiological under contrasted environments identifying suitable heterotic method superior hybrid production. For this purpose, nineteen accessions representing different origins population structure West African...
Abstract Pearl millet, unlike other cereals, is able to withstand dry and hot conditions plays an important role for food security in arid semi-arid areas of Africa India. However, low soil fertility drought constrain pearl millet yield. One the main targets address these constraints through agricultural practices or breeding root system architecture. In this study, order easily phenotype field conditions, we developed a model predict length density (RLD) plants from intersection densities...
Objective: To obtain high yields under more and irregular agro-climatic conditions, varieties with resistance to drought in different stages of their cycles are necessary.
