  • The Ludhiana-based university has come up with a new wheat variety called PBW RS1.
  • It contains high levels of amylose starch.
  • RS is short for resistant starch.
  • It is known to reduce the risk of type-2 diabetes and cardiovascular diseases.
  • The consumption of chapatis made from this wheat won't lead to an immediate and rapid rise in glucose levels.
  • High-amylose starch has unique functional properties and nutritional values in food applications.
  • This form of starch is resistant to enzymatic digestion in the gastrointestinal tract and contains a higher fraction of resistant starch.
  • The high amylose and resistant starch make sure that glucose is released more slowly into the bloodstream.
  • This slow digest also increases a feeling of satiety.
  • The new wheat has a total starch content which is almost equivalent to 66-70 per cent in other wheat varieties.
  • However, it has 30.3 per cent resistant starch content as against only 7.5-10 per cent for other varieties, including PBW 550, PBW 725, HD 3086 and PBW 766.
  • The field trials have been recorded at 43.18 quintals per hectare.
