Analysis on Heterosis of Wet Gluten Content and Gluten Index in Wheat
Heterosis of wet gluten content and gluten index were studied with 32 crosses from 4 strong gluten parents and 4 mid or weak gluten parents by NC II design. The result showed that heterosis of wet gluten content was lower, and heterosis of gluten index was higher. Only 2 crosses showed positive heterosis of wet gluten content (not significant) , and others showed negative heterosis, of which 5 crosses reached significant level. 26 crosses performed positive heterosis of gluten index, of which 6 crosses reached significant level and 4 crosses reached very significant level, although other 6 crosses showed negative heterosis, but all of them were not significant.
