  • The high amylose and resistant starch ensure that glucose is released slowly into the bloodstream, preventing an immediate rise in glucose levels and reducing the risk of diabetes and cardiovascular diseases.
  • It has a total starch content similar to other wheat varieties but contains 30.3% resistant starch, compared to only 7.5-10% in other varieties.
  • It has lower productivity compared to other wheat varieties, with an average grain yield of 43.18 quintals per hectare, below the average yield in Punjab.
  • Reduce the risks of type-2 diabetes and
