For decades, agricultural research programs have worked to develop improved varieties that are more resistant to pests, diseases, and climate change. However, ensuring that these varieties reach farmers does not automatically guarantee better harvests.<\/p>\n<p>An international team of researchers, with participation from Zamorano, the International Center for Tropical Agriculture (CIAT), and Guatemala\u2019s Institute of Agricultural Science and Technology (ICTA), analyzed the extent to which farmers in Guatemala, Honduras, Nicaragua, and Haiti have adopted improved bean varieties and whether this adoption has actually resulted in higher yields.&nbsp;<\/p><p>The results, published in the journal Agricultural Systems, reveal a surprising situation: in several countries, the use of improved seeds did not translate into better harvests, while in others, significant gains were achieved even with low adoption levels.<\/p>\n<p>The study also found signs of genetic contamination within formal seed production systems, compromising the quality of the varieties distributed to farmers. These findings highlight that strengthening seed quality control\u2014not only developing new varieties\u2014is essential to ensure that agricultural research truly benefits producers. The research included the participation of Dr. Juan Carlos Rosas, professor emeritus at Zamorano University.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-cc18189 elementor-widget elementor-widget-text-editor\" data-id=\"cc18189\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>For more information:<\/p><p class=\"p1\">jcrosas@zamorano.edu<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-28ef1c6 elementor-widget elementor-widget-button\" data-id=\"28ef1c6\" data-element_type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-button-wrapper\">\n\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S0308521X25001878\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Read the study here<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-08f3a85 elementor-widget__width-initial elementor-widget elementor-widget-image\" data-id=\"08f3a85\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img alt=\"\" fetchpriority=\"high\" decoding=\"async\" width=\"1000\" height=\"667\" src=\"https:\/\/zamorano.edu\/wp-content\/uploads\/2026\/07\/2732.webp\" class=\"attachment-large size-large wp-image-1012938\" srcset=\"https:\/\/zamorano.edu\/wp-content\/uploads\/2026\/07\/2732.webp 1000w, https:\/\/zamorano.edu\/wp-content\/uploads\/2026\/07\/2732-300x200.webp 300w, https:\/\/zamorano.edu\/wp-content\/uploads\/2026\/07\/2732-768x512.webp 768w, https:\/\/zamorano.edu\/wp-content\/uploads\/2026\/07\/2732-18x12.webp 18w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e5132c3 elementor-widget elementor-widget-text-editor\" data-id=\"e5132c3\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>(Image by Magnific)<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>Beans are one of the most important foods in the diets of Central America and Haiti.
