“A Quantitative Genomics Map of Rice Provides Genetic Insights and Guides Breeding”, 2021-02-01 (; similar):
Extensive allelic variation in agronomically important genes serves as the basis of rice breeding.
Here, we present a comprehensive map of rice quantitative trait nucleotides (QTNs) and inferred QTN effects based on 8 genome-wide association study cohorts.
Population genetic analyses revealed that domestication, local adaptation and heterosis are all associated with QTN allele frequency changes.
A genome navigation system, RiceNavi, was developed for QTN pyramiding and breeding route optimization, and implemented in the improvement of a widely cultivated indica variety.
This work presents an efficient platform that bridges ever-increasing genomic knowledge and diverse improvement needs in rice.
