Research on the effect of split nitrogen application on wheat grain yield and quality under conservation agriculture. The study was conducted during the 2016-2017 and 2017-2018 fall-winter cycles in the Bajío region of Guanajuato. The effects of study locations, wheat varieties, nitrogen fractionation, and their interactions were evaluated.
Wheat head blast index (%) data for four CIMMYT nurseries (15HLBSN, 15HZAN, 41SAWSN, and 56IBWSN) is presented. Field trials took place in Quirusillas and Okinawa (Bolivia) and Jashore (Bangladesh) during the 2024 cycles. Two sowings were made in each location/cycle except for Quirusillas where only one sowing was made.
This dataset was collected in 2023 as part of a consumer research study conducted in Nairobi, Kenya, aimed at assessing the acceptance of wheat flour blended with underutilized crops—sorghum, millet, and cassava. A total of 1,871 consumers participated in structured sensory evaluations of chapati and bread prepared using wheat flour blended at varying ratios (up to 20%). The study employed both blind and informed tasting approaches to assess product preferences and willingness to pay. After the sensory tests, participants were given a one-kilogram package of blended flour for home use, followed by a phone-based survey capturing their real-life cooking experiences and post-use perceptions. The dataset provides comprehensive details on participants' demographics and socioeconomic profiles, along with individual preferences for each food product, including sensory evaluation scores and rankings. It also includes data on participants' willingness to pay, based on different information treatments. In addition, the dataset captures responses from a follow-up survey, offering insights into participants' experiences, satisfaction, and acceptance of the blended flour products after using them at home.
A number of BNI short arm (T3BL.3NsbS) translocation lines and their recurrent parents were fingerprinted with the DArTAGTM bread wheat SNP panel which is included in the CGIAR mid-density genotyping services (https://excellenceinbreeding.org/toolbox/services/mid-density-genotyping-service). This data server as a pedigree verification data set for the translocation lines.
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.
