Implication

Randomized block experiment demonstrates that sowing date alters blast disease intensity and grain yield in wheat genotypes, highlighting planting schedules as an effective management strategy.

Key Points

To evaluate the effect of sowing date on wheat blast disease intensity and subsequent grain yield losses across diverse wheat (Triticum aestivum) genotypes.
Field trials were conducted in 2013 in Minas Gerais, Brazil, using a randomized complete block design with three replicates.
Evaluated 14 wheat genotypes across two distinct sowing dates, measuring disease incidence, severity, disease index (DI), thousand grain weight (TGW), and grain yield.
Sowing date significantly affected disease index, thousand grain weight, and grain yield.
Disease index correlated strongly with yield losses (r = 0.89), with DI values ≥ 0.5 corresponding to yield losses ≥ 70%.
Yield losses correlated negatively with thousand grain weight (r = -0.85) and grain yield (r = -0.93), with genotypes EP063030, MGS Brilhante, and BRS 264 demonstrating the highest tolerance under high disease pressure.
