From tradition to trait: stay-green alleles in Sudanese Feterita unlock pathways to climate-resilient sorghum.

ABSTRACT:

Introduction

Sorghum is a vital crop for food and nutritional security in drought-prone regions. However, the genetic potential of Sudanese Feterita landraces for stay-green (Stg) traits remains largely unexplored.

Methods

This study evaluated 133 Feterita genotypes using an integrated approach combining field phenotyping with KASP genotyping targeting the Stg3A and Stg3B QTLs. The genotypes were assessed during the 2022 season at the Gezira Research Station using an augmented design, and 14 morphological and agronomic traits were recorded for each genotype.

Results and discussion

Substantial phenotypic variation was observed, with particularly high coefficients of variation for flowering stalks per plant (81.25%), senescence (49.09%
