Summary

Story summary

ICRISAT identifies 13 genomic regions and 145 candidate genes linked to stem rot resistance in groundnut.
Key genes AhSR001, AhSR002, and AhSR003 explain about 60% of resistance, accelerating breeding.
Stem rot can cut yields up to 80%; groundnut supports diets and economies in Asia and Africa (India, Nigeria, China), with Indian and Chinese institutions and the Gates Foundation providing support.
