Stay-green (SG) in wheat is a beneficial trait that increases yield and stress tolerance. However, conventional phenotyping techniques limited the understanding of its genetic basis. Spectral indices (SIs) as non-destructive tools to evaluate crop temporal senescence provide an alternative strategy.

- Stripe rust is a significant threat to wheat crops globally, and the Chinese cultivar Lanhangxuan 121 (LHX121) shows greater resistance than its parent, L92-47, owing to space mutation breeding.
- This research aimed to identify resistance genes in both LHX121 and L92-47 by creating segregating populations and analyzing their responses to stripe rust in multiple environments over two years.
- QTL mapping revealed resistance loci in both cultivars, suggesting that LHX121 may harbor a novel resistance QTL on chromosome 5B, contributing to improved understanding of wheat's genetic defenses against stripe rust.
