Replication Data for: Study of Post-flowering stalk rot (PFSR) pathogen species variation and possible shifts across selected maize agro-ecologies in South Asia

Zerka Rashid Sudha Nair (2023, [Dataset])

Maize post-flowering stalk rots (PFSR) are caused by at least six genera of fungal pathogens. They generally occur as a complex, along with secondary colonizers. PFSR are reported from all major maize growing ecologies and are expected to be exacerbated by the changing climates in Latin America, Asia, and Sub-Saharan Africa, A better understanding of the prevalence and spread of the stalk rot pathogens in different maize agro ecologies in Asia could contribute to plans to reduce damage caused by PFSRs. The data presented in this study from from a collection of samples from PFSR-affected maize plant stalks in India. The samples were collected in 2022 from 19 locations. The results of the analysis of the pathogens are presented in the report present in this study and accompanying article.

Replication Data for: Exotic alleles contribute to heat tolerance in wheat under field conditions

Gemma Molero Benedict Coombes Ryan Joynson Francisco Pinto Francisco Javier Pinera-Chavez Carolina Rivera-Amado Anthony Hall Matthew Paul Reynolds (2023, [Dataset])

Plant breediers must respond to the threats posed by climate change in order to help ensure global food security in the short and long term. A better understanding of the genetic underpinnings of heat tolerance can contribute to efforts to develop more resilient crops. The exome capture data from 149 spring wheat lines provided in this dataset were used to search for loci, including loci from an exotic wheat relative, that could contribute to enhanced heat tolerance. The HIBAP_Germplasm file provides a HIBAP_NUMBER that appears in name of the exome capture files to link them to specific germplasm.The methods and results of the study are described in the accompanying article.

Replication Data for: Elucidating Genetic Control of Maydis Leaf Blight Resistance in Tropical Maize Through Genome Wide Association Studies and Genomic Predictions

Wajhat Un nisa Surinder K. Sandhu Sudha Nair Harleen Kaur Dr Ashok Kumar Zerka Rashid GAJANAN SAYKHEDKAR (2023, [Dataset])

Maydis Leaf Blight (MLB) is a serious foliar disease for maize in warm and humid regions. The data in this dataset were used to investigate the genetic architecture underlying resistance to MLB using high resolution Genome Wide Association Studies and Genomic Prediction. A diverse panel of 336 maize inbreds adapted for the Asian tropics, were evaluated for MLB disease score under four environments using artificial inoculation. In addition, a set of high density SNPs (128,490) from genotyping by sequencing were used for the study. The results of this study are presented in the accompanying publication.

Consumers’ study with instant fortified pearl millet products using affective tests and experimental auctions in Touba, Senegal

Hugo De Groote Sarah Kariuki John Taylor Mario Ferruzzi Bruce Hamaker (2022, [Dataset])

For this study, 201 consumers from Touba Senegal, were invited to evaluated four new flour products in comparison with the conventional pearl millet flours: instant pearl millet flour, instant pearl millet flour pearl millet flour, instant pearl millet flour with added dry mango and carrot powder (Food-to-Food fortification), and the previous product with added conventional chemical added dry mango and carrot powder (naturally fortified), and the previous products with added conventional chemical micronutrient premix and the food-to-food fortification. Consumers' acceptance was measured with affective tests on all the products, prepared as porridge, on five sensory traits: appearance, aroma, texture, taste and overall- score, using a five-point Likert scale (1 = dislike very much, 2 = dislike, 3 = neither dislike nor like, 4 = like, 5 = like very much. Willingness to pay (WTP) for the products was elicited through experimental auctions, in particular the BDM mechanism. Participants were randomly divided into two information treatments: in the first group the WTP was first elicited without information on the product’s content, followed by the same WTP experiment after providing information; in the second group information was given directly followed by the WTP experiment.

Supplemental data for deciphering resistance to Zymoseptoria tritici in the Tunisian durum wheat landrace accession ‘Agili39’

Karim Ammar Susanne Dreisigacker (2021, [Dataset])

Two major and two minor QTL for seedling and adult-plant resistance to Septoria tritici blotch (STB), caused by the fungus Zymoseptoria tritici (Z. tritici) were mapped. The two mayor QTL were located on chromosome 2B, the two minor QTL on chromosomes 1A and 7A, respectively and derived from the Tunisian durum wheat landrace accession ‘Agili39’. QTL were mapped in a recombinant inbred population, phenotyped for STB resistance using a wide array of isolates and genotyped using the high density DArTSeq platform.
