Plant Breeding and Genomics at eXtension.org provides research-based educational materials for plant breeding professionals, students, and educators. Our goal is to efficiently share plant breeding and genomics knowledge. PBG tutorials detail basic plant breeding and genomics concepts as well as the application of genomic data to breeding programs. We strive to connect the plant breeding community to rapidly developing advances in technology and publically available genomic data. Many of our tutorials demonstrate computational tools using sample data, allowing learners to replicate the demonstration and gain proficiency.
