Wheat is the most important triticeae crops in the world, and its grain hardness is related to the processing quality and edible quality, as well as enterprise benefit and farmer income. The crops of triticeae grain hardness test method, the relationship between the grain hardness and grain composition, grain hardness and molecular mechanism research progress, the grain hardness genes and research progress of the correlation of quality traits were summarized, and put forward the prospect for future development, aimed at triticeae crops genetic breeding and quality improvement to provide the reference.

[Objective] In order to accelerate the progress for the improvement of quality breeding, the present study was used to characterize the allelic variations of genes which related grain hardness and resistance to pre-harvest sprouting (PHS) in Sichuan wheat cultivars. [Method] With 2 molecular markers of grain hardness, 1 functional markers of resistance to PHS, 105 Sichuan wheat cultivars which released since 2000 were detected. [Result]The results showed that; (I) For grain hardness, 11 cultivars contained Pinb-Dlb (Pinb mutation), with a frequency of 10.5 %; non-Pinb-Dl b was detected in 94 cultivars, with a frequency of 89.5 %. (II) For the resistance to PHS, 88 cultivars had allele Vp-lBc (resistance to PHS), with a frequency of 83.8 % ; 17 carried Vp-lBa (susceptible to PHS), with a frequency of 16.2 %. Vp-IBb (resistance to PHS) was not detected in the varieties. (III) 11 excellent sichuan wheat cultivars had 2 good quality genes combination (Pinb-Dlb and Vp-lBc), with a frequency of 10.5 %. [Conclusion] Pyramiding a number of good genes as Pinb-Dlb and Vp-lBc was the effective way to improve the quality of Sichuan wheat cultivars. [ABSTRACT FROM AUTHOR]
