“…Out of these materials, four stood out in the production of forage and seeds (Terrazas and Chávez, 2012a;Terrazas and Chávez, 2012b). In a study that evaluated a collection of 126 ecotypes in Africa, values ranging from 1302 to 7442 kg MS ha -1 were reported (Sánchez-Gutiérrez et al, 2017), which sustains the need to evaluate materials in the same species to give pertinent recommendations for their use. In Zacatecas, Mexico, there is an optimal and suboptimal potential area for Buffel grass of 96 624 and 2 693 005 ha, respectively (Medina et al, 2001).…”

Buffel grass (Cenchrus ciliare L.) is a species used for the production of forage that is characterized by its adequate adaptation to diverse environments. The aim was to evaluate the characteristics of forage and seeds from four materials and a variety of Buffel grass under rainfed conditions in the semi-dry and semi-warm weather of Zacatecas. The experiment was held in Huanusco, Zacatecas, Mexico, in a totally randomized block design with three replications. The materials were: M-42, M-45, M-66, M-S245, and the Titán variety as a control. For forage, two cuts were performed, considering the variables of plant height (PH), production of dry matter (DM), crude protein (CP), and in vitro digestibility of dry matter (IVDDM). Seed characteristics were determined upon physiological maturity using the variables of seed yield (SY), number of spikes per plant (Sp/plt), caryopsides per spikelet (Car/sp), and area of caryopsides (Area/Car). The data were analyzed in SAS, and the means were compared using Lsmeans. For the variable PH, M-42 stood out with an average height of 97.3 cm. In the production of DM, M-42 and M-45 surpassed Titán (p < 0.05), with yields higher than 4.4 Mg ha-1. M-42 had the greatest CP content at 7.29 %, whereas M-45 and M-S245 had the highest IVDDM concentrations at 74.5 and 74.8 %, respectively. Regarding seed characteristics, M-42 surpassed Titán, with a SY of 295 kg ha-1. The study concluded that M-42 is the best option for grassland management in Zacatecas, Mexico, where the weather is semi-warm and semi-dry.

“…The phenotypic data were collected from a field experiment as described elsewhere [33] and used for GWAS. Briefly, the experiment was established in 2014 during the main rainy season at the Bishoftu field genebank, Bishoftu, Ethiopia [33]. All the accessions evaluated in the experiment were obtained from the Zwai field genebank, Zwai, Ethiopia.…”

“…The International Livestock Research Institute (ILRI) holds a large collection of buffel grass germplasm collected from different countries in Africa and Asia [9]. Agro-morphological studies have revealed the diversity embedded in the buffel grass collection maintained in the forage genebank at ILRI [32,33]. Facultative apomictic lines that could offer a potential resource for forage breeding programs to generate new and improved varieties have also been identified in the collection [34].…”

“…Thus, in this current study, we envisage filling this gap by employing a genome-wide association study for biomass yield and feed quality traits. Here we leveraged the data generated from previous agro-morphological [33] and genotyping studies [9], and present a genome-wide association study (GWAS) for biomass yield and feed quality traits in buffel grass.…”

The development of modern genomic tools has helped accelerate genetic gains in the breeding program of food crops. More recently, genomic resources have been developed for tropical forages, providing key resources for developing new climate-resilient high-yielding forage varieties. In this study, we present a genome-wide association study for biomass yield and feed quality traits in buffel grass (Cenchrus ciliaris L. aka Pennisetum ciliare L.). Genome-wide markers, generated using the DArTSeq platform and mapped onto the Setaria italica reference genome, were used for the genome-wide association study. The results revealed several markers associated with biomass yield and feed quality traits. A total of 78 marker–trait associations were identified with R2 values ranging from 0.138 to 0.236. The marker–trait associations were distributed across different chromosomes. Of these associations, the most marker–trait associations (23) were observed on Chr9, followed by Chr5 with 12. The fewest number of marker–trait associations were observed on Chr4 with 2. In terms of traits, 17 markers were associated with biomass yield, 24 with crude protein, 26 with TDN, 14 with ADF, 10 with NDF and 6 with DMI. A total of 20 of the identified markers were associated with at least two traits. The identified marker–trait associations provide a useful genomic resource for the future improvement and breeding of buffel grass.
