Annotation
A two-year field trial (2024–2025) was conducted to evaluate the agronomic performance of 11 wheat accessions, under rainfed conditions of Uzbekistan. Significant variation was observed in plant height, thousand kernel weight (TKW), days to heading and maturity and grain yield across years and accessions and varieties, reflecting differential responses to stress. Lalmikor-1 demonstrated superior stability in plant height (97 cm and 94 cm), kernel weight (40.2 g and 38.4 g), and yield (2.89 t/ha and 1.36 t/ha), outperforming the standard variety by 32–42%. These findings highlight the potential of this variety for wheat production programs targeting yield stability in drought affected years.
