Genetics and Grain Filling Effects on Starch Properties in Wheat.

ABSTRACT: The physicochemical properties of wheat (Triticum aestivum L.) determine its application. This study aims to investigate the genetic patterns and heterosis performance of physicochemical properties of wheat starch, using the variety Xinong99 and two filling-deficient mutants, dwarf wrinkle grain (dwg) and dwarf narrow grain (dng), obtained by EMS mutagenesis, as well as their backcross F1 generations, to systematically compare differences in starch structure, pasting characteristics, and thermal properties. The results showed that the mutants exhibited higher relative crystallinity, significantly reduced starch content and gelatinization temperature, while the gelatinization enthalpy and breakdown viscosity were significantly increased. Some F1 generation germplasm exh
